SGM4T245
4-Bit Dual-Supply Bus
Transceiver with Configurable
Voltage Translation and 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The SGM4T245 is a 4-bit, dual-supply bus transceiver
● VCCA Supply Voltage Range: 1.2V to 5.0V
with configurable voltage translation and 3-state
● VCCB Supply Voltage Range: 1.2V to 5.0V
outputs. The device can be used as two 2-bit
● Input and Output Interface Capability to 6V
transceivers or as a 4-bit transceiver. The nAn and nBn
are four 2-bit input and output ports. nDIR are the
����� are the output enable
direction control inputs and nOE
inputs. VCCA and VCCB are the supply pins. The supply
System Environment
● Control Inputs Levels are Referenced to VCCA
● Outputs in High-Impedance State when VCCA or
VCCB = 0V
voltage of VCCA and VCCB can range from 1.2V to 5.0V,
● Support Partial Power-Down Mode
making the device suitable for bidirectional translating
● -40℃ to +125℃ Operating Temperature Range
between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and
● Available in Green TSSOP-16 and TQFN-2.6×1.8-16L
5.0V voltage nodes.
����� and nDIR are referenced to VCCA and
Pins nAn, nOE
nBn pins are referenced to VCCB. When nDIR is set high,
it allows transmission from nAn to nBn. When nDIR is
�����
set low, it allows transmission from nBn to nAn. nOE
can be used to make the outputs disabled so that the
buses are effectively isolated. In suspend mode, both
nAn and nBn are in high-impedance state when either
VCCA or VCCB input is at GND level.

APPLICATIONS
Personal Electronic
Industrial Equipment
Enterprise Infrastructures
Telecom Equipment
This device is highly suitable for partial power-down
applications using power-off leakage current (IOFF)
circuit. When the device is powered down, the current
backflow will be prevented from passing through the
device.
OE should be tied to VCC through a pull-up resistor, in
order to make sure the high-impedance state during
power-up or power-down, the minimum resistance
depends on the current-sinking capability of the driver.
The SGM4T245 is available in Green TSSOP-16 and
TQFN-2.6×1.8-16L packages. It operates over an
ambient temperature range of -40℃ to +125℃.

OVERSTRESS CAUTION
1. Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods may
affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
2. The input and output negative voltage ratings may be
exceeded if the input and output clamp current ratings are
observed.
3. The performance capability of a high-performance integrated
circuit in conjunction with its thermal environment can create
junction temperatures which are detrimental to reliability.
ESD SENSITIVITY 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.

NOTES:
1. Power dissipation capacitance per transceiver.
2. CPD is used to determine the dynamic power dissipation (PD in μW).

PD = CPD × VCC × fi × N + Σ(CL × VCC × fo)
where:
fi = Input frequency in MHz.
fo = Output frequency in MHz.
CL = Output load capacitance in pF.
VCC = Supply voltage in Volts.
N = Number of inputs switching.

Σ(CL × VCC × fo) = Sum of the outputs.
