NTS0101
Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 5 — 11 August 2014
Product data sheet
1. General description
The NTS0101 is a 1-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 1-bit input-output ports
(A and B), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A)
can be supplied at any voltage between 1.65 V and 3.6 V. VCC(B) can be supplied at any
voltage between 2.3 V and 5.5 V. This flexibility makes the device suitable for translating
between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins A and OE are
referenced to VCC(A) and pin B is referenced to VCC(B). A LOW level at pin OE causes the
outputs to assume a high-impedance OFF-state. This device is fully specified for partial
power-down applications using IOFF. The IOFF circuitry disables the output, preventing the
damaging backflow current through the device when it is powered down.
2. Features and benefits
Wide supply voltage range:
VCC(A): 1.65 V to 3.6 V and VCC(B): 2.3 V to 5.5 V
Maximum data rates:
Push-pull: 50 Mbps
IOFF circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114E Class 2 exceeds 2500 V for A port
HBM JESD22-A114E Class 3B exceeds 8000 V for B port
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1500 V
Latch-up performance exceeds 100 mA per JESD 78B Class II
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C

14. Application information
14.1 Applications
Voltage level-translation applications. The NTS0101 can be used in point-to-point
applications to interface between devices or systems operating at different supply
voltages. The device is primarily targeted at I2C or 1-wire which use open-drain drivers. It
may also be used in applications where push-pull drivers are connected to the ports,
however the NTB0101 may be more suitable.

Architecture of NTS0101 I/O cel
The NTS0101 is a "switch" type voltage translator, it employs two key circuits to enable
voltage translation:
1. A pass-gate transistor (N-channel) that ties the ports together.
2. An output edge-rate accelerator that detects and accelerates rising edges on the I/O
pins.

NTS0101
NXP Semiconductors
Dual supply translating transceiver; open drain; auto direction sensing
The gate bias voltage of the pass gate transistor (T3) is set at approximately one
threshold voltage above the VCC level of the low-voltage side. During a LOW-to-HIGH
transition, the output one-shot accelerates the output transition by switching on the PMOS
transistors (T1, T2). It bypasses the 10 k pull-up resistors and increases the current
drive capability. The one-shot is activated once the input transition reaches approximately
VCCI/2; it is de-activated approximately 50 ns after the output reaches VCCO/2. During the
acceleration time, the driver output resistance is between approximately 50 and 70 .
To avoid signal contention and minimize dynamic ICC, the user should wait for the
one-shot circuit to turn-off before applying a signal in the opposite direction. Pull-up
resistors are included in the device for DC current sourcing capability.
14.3 Input driver requirements
As the NTS0101 is a switch type translator, properties of the input driver directly effect the
output signal. The external open-drain or push-pull driver applied to an I/O determines the
static current sinking capability of the system. The max data rate, HIGH-to-LOW output
transition time (tTHL), and propagation delay (tPHL), are dependent upon the output
impedance and edge-rate of the external driver. The limits provided for these parameters
in the data sheet assume a driver with output impedance below 50 is used.
14.4 Output load considerations
The maximum lumped capacitive load that can be driven is dependant upon the one-shot
pulse duration. In cases with very heavy capacitive loading, there is a risk that the output
does not reach the positive rail within the one-shot pulse duration.
To avoid excessive capacitive loading and to ensure correct triggering of the one-shot,
use short trace lengths and low capacitance connectors on NTS0101 PCB layouts. The
length of the PCB trace should be such that the round-trip delay of any reflection is within
the one-shot pulse duration (approximately 50 ns). It ensures low impedance termination
and avoids output signal oscillations and one-shot retriggering.
14.5 Power-up
During operation, VCC(A) must never be higher than VCC(B). However, during power-up,
VCC(A) VCC(B) does not damage the device, so either power supply can be ramped up
first. There is no special power-up sequencing required. The NTS0101 includes circuitry
that disables all output ports when either VCC(A) or VCC(B) is switched off.
14.6 Enable and disable
An output enable input (OE) is used to disable the device. Setting OE = LOW causes all
I/Os to assume the high-impedance OFF-state. The disable time (tdis with no external
load) indicates the delay between when OE goes LOW and when outputs actually
become disabled. The enable time (ten) indicates the amount of time the user must allow
for one one-shot circuitry to become operational after OE is taken HIGH. To ensure the
high-impedance OFF-state during power-up or power-down, pin OE should be tied to
GND through a pull-down resistor. The current-sourcing capability of the driver determines
the minimum value of the resistor.

14.7 Pull-up or pull-down resistors on I/Os lines
The A port I/O has an internal 10 k pull-up resistor to VCC(A). The B port I/O has an
internal 10 k pull-up resistor to VCC(B). If a smaller value of pull-up resistor is required,
add an external resistor in parallel to the internal 10 k. This pull-up resistor effects the
VOL level. When OE goes LOW, the internal pull-ups of the NTS0101 are disabled.

authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
