2-Bit Bidirectional Voltage-Level Translator
for Open-Drain and Push-Pull Applications
GENERAL DESCRIPTION
FEATURES
This two-bit non-inverting translator is a bidirectional
voltage-level translator and can be used to establish
digital switching compatibility between mixed-voltage
systems. It uses two separate configurable power-supply
rails, with the A ports supporting operating voltages from
1.65V to 5.5V while it tracks the VCCA supply, and the B
ports supporting operating voltages from 2.3V to 5.5V
while it tracks the VCCB supply. This allows the support of
both lower and higher logic signal levels while providing
bidirectional translation capabilities between any of the
1.8V, 2.5V, 3.3V, and 5V voltage nodes.
No Direction-Control Signal Needed
Data Rates
24Mbps (Push-Pull)
2Mbps (Open-Drain)
1.65V to 5.5V on A Ports and 2.3V to 5.5V on B Ports
(VCCA ≤ VCCB)
VCC Isolation: If Either VCC is at GND,
Both Ports are in the High-Impedance State
No Power-Supply Sequencing Required:
Either VCCA or VCCB can be Ramped First
IOFF: Supports Partial-Power-Down Mode Operation
Available in Green SOT-23-8 and XTDFN-1.4×1-8L
Packages
When the output-enable (OE) input is low, all I/Os are
placed in the high-impedance state, which significantly
reduces the power-supply quiescent current consumption.
OE has an internal pull-down current source, as long as
VCCA is powered.
To ensure the high-impedance state during power up or
power down, OE should be tied to GND through a
pull-down resistor; the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
APPLICATIONS
I2C/SMBus
UART
GPIO
The SGM4553 is available in the Green SOT-23-8 and
XTDFN-1.4×1-8L packages. It operates over an ambient
temperature range of -40℃ to +85℃.

NOTES:
1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections
of the specifications is not implied. Exposure to absolute Maximum rating conditions for extended periods may affect device reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
3. The value of VCCA and VCCB are provided in the recommended operating conditions table.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause
damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at
any time. Please contact SGMICRO sales office to get the latest datasheet.

2-Bit Bidirectional Voltage-Level Translator
for Open-Drain and Push-Pull Applications
SGM4553
APPLICATION INFORMATION
Applications
The SGM4553 can be used to bridge the digital-switching
compatibility gap between two voltage nodes to
successfully interface logic threshold levels found in
electronic systems. It should be used in a point-to-point
topology for interfacing devices or systems operating at
different interface voltages with one another. Its primary
target application use is for interfacing with open-drain
drivers on the data I/Os such as I2C or 1-wire, where the
data is bidirectional and no control signal is available.
The SGM4553 can also be used in applications where a
push-pull driver is connected to the data I/Os.
Architecture
The SGM4553 architecture (see Figure 1) is an
auto-direction-sensing based translator that does not
require a direction-control signal to control the direction of
data flow from A to B or from B to A.
These two bidirectional channels independently determine
the direction of data flow without a direction-control signal.
Each I/O pin can be automatically reconfigured as either
an input or an output, which is how this auto-direction
feature is realized.

Input Driver Requirements
The fall time (tfA, tfB) of a signal depends on the output
impedance of the external device driving the data I/Os of
the SGM4553. Similarly, the tPHL and data rates also
depend on the output impedance of the external driver.
The values for tfA, tfB, tPHL, and data rates in the datasheet
assume that the output impedance of the external driver
is less than 50Ω.
Power Up
During operation, ensure that VCCA ≤ VCCB at all times.
The sequencing of each power supply will not damage
the device during the power up operation, so either power
supply can be ramped up first.
Output Load Considerations
VCCB
VCCA
The SGM4553 employs two key circuits to enable this
voltage translation:
An N-channel pass-gate transistor topology that ties
the A port to the B port.
Output one-shot (O.S.) edge-rate accelerator
circuitry to detect and accelerate rising edges on the
A or B ports.
We recommend careful PCB layout practices with short
PCB trace lengths to avoid excessive capacitive loading
and to ensure that proper O.S. triggering takes place.
PCB signal trace-lengths should be kept short enough
such that the round trip delay of any reflection is less than
the one-shot duration. This improves signal integrity by
ensuring that any reflection sees a low impedance at the
driver. The O.S. circuits have been designed to stay on
for approximately 30ns. The maximum capacitance of the
lumped load that can be driven also depends directly on
the one-shot duration. With very heavy capacitive loads,
the one-shot can time-out before the signal is driven fully
to the positive rail. The O.S. duration has been set to best
optimize trade-offs between dynamic ICC, load driving
capability, and maximum bit-rate considerations. Both
PCB trace length and connectors add to the capacitance
that the SGM4553 output sees, so it is recommended
that this lumped-load capacitance be considered to avoid
O.S. retriggering, bus contention, output signal
oscillations, or other adverse system-level affects.

APPLICATION INFORMATION
Enable and Disable
Pull-Up or Pull-Down Resistors on I/O Lines
The SGM4553 has an OE input that is used to disable the
device by setting OE low, which places all I/Os in the Hi-Z
state. OE has an internal pull-down current source, as
long as VCCA is powered. The disable time (tDIS) indicates
the delay between the time when OE goes low and when
the outputs are disabled (Hi-Z). The enable time (tEN)
indicates the amount of time the user must allow for the
one-shot circuitry to become operational after OE is
taken high.
Each A port I/O has an internal 10kΩ pull-up resistor to
VCCA, and each B port I/O has an internal 10kΩ pull-up
resistor to VCCB. If a smaller value of pull-up resistor is
required, an external resistor must be added from the I/O
to VCCA or VCCB (in parallel with the internal 10kΩ
resistors). Adding lower value pull-up resistors will affect
VOL levels, however. The internal pull-ups of the
SGM4553 are disabled when the OE pin is low.

NOTES:
1. CL includes probe and jig capacitance.
2. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.
3. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10MHz, ZO = 50Ω, dv/dt ≥ 1V/ns.
4. The outputs are measured one at a time, with one transition per measurement.
5. tPLZ and tPHZ are the same as tDIS.
6. tPZL and tPZH are the same as tEN.
7. tPLH and tPHL are the same as tPD.
8. VCCI is the VCC associated with the input ports.
9. VCCO is the VCC associated with the output ports.
10. All parameters and waveforms are not applicable to all devices.
