74AVC16T245
16-Bit Dual-Supply Translating
Transceiver with Configurable
Voltage Translation and 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The 74AVC16T245 is a 16-bit dual-supply translating
transceiver with configurable voltage translation and
3-state outputs. The device can be used as two 8-bit
transceivers or one 16-bit transceiver. The nAn and
nBn are two 8-bit input-output data ports. nDIR are the
● 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:
�����
direction control inputs and nOE are the output enable
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
inputs. 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-48 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 the
high-impedance state when either VCCA or VCCB input is
at GND level.
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.

Active Mode
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.

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.............................................................................8000V
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.
RECOMMENDED OPERATING CONDITIONS
