74AVC4T245
4-Bit Dual-Supply
Translating Transceiver with Configurable
Voltage Translation and 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The 74AVC4T245 is a 4-bit, dual-supply voltage level
transceiver with 3-state outputs and bidirectional level
translation. The device can be used as two 2-bit
transceivers or one 4-bit transceiver. The nAn and nBn
are four data input-output ports. nDIR are the direction
● VCCA Supply Voltage Range: 0.8V to 3.6V
● VCCB Supply Voltage Range: 0.8V to 3.6V
● Inputs Accept Voltages up to 3.6V
● +12mA/-12mA Output Current
● Data Rates:
�����
control inputs and nOE are the output enable inputs.
380Mbps (≥ 1.8V to 3.3V Translation)
200Mbps (≥ 1.1V to 3.3V Translation)
200Mbps (≥ 1.1V to 2.5V Translation)
200Mbps (≥ 1.1V to 1.8V Translation)
150Mbps (≥ 1.1V to 1.5V Translation)
100Mbps (≥ 1.1V to 1.2V Translation)
● Outputs in High-Impedance State when VCCA or
VCCA and VCCB are the supply pins. The supply voltage
of VCCA and VCCB can range from 0.8V to 3.6V, making
the device suitable for bidirectional translating among
any of the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V
�����
voltage nodes. The nAn, nDIR and nOE signals are
referenced to VCCA and nBn signals are referenced to
VCCB
.
VCCB = 0V
● -40℃ to +125℃ Operating Temperature Range
● Available in a Green TSSOP-16 Package
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.

1. Stresses beyond those listed in Absolute Maximum
Ratings may cause permanent damage to the device.
Exposureto 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.

ESD Susceptibility
2. The minimum input voltage ratings and output voltage
ratings may be exceeded if the input and output 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
HBM.............................................................................6000V
CDM ............................................................................1000V
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
