74AVCH2T45
2-Bit Dual-Supply Voltage
Level Transceiver with 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The 74AVCH2T45 is a 2-bit, dual-supply voltage level
transceiver. The nA and nB are two data input-output
ports, DIR is a direction control input, and VCCA and
● 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
VCCB are dual-supply pins. The supply voltage of VCCA
and VCCB can range from 0.8V to 3.6V, making the
device suitable for translating among any of the 0.8V,
1.2V, 1.5V, 1.8V, 2.5V and 3.3V voltage nodes. The nA
and DIR signals are referenced to VCCA and nB signals
● Data Rates:
500Mbps (1.8V to 3.3V Translation)
320Mbps (< 1.8V to 3.3V Translation)
320Mbps (Translate to 2.5V or 1.8V)
280Mbps (Translate to 1.5V)
are referenced to VCCB
.
240Mbps (Translate to 1.2V)
When DIR is set high, it allows transmission from nA to
nB. When DIR is set low, it allows transmission from nB
to nA. In suspend mode, when either VCCA or VCCB input
is at GND, both nA and nB are in the high-impedance
state.
● Outputs in High-Impedance State when VCCA or
VCCB = 0V
● No External Pull-up/Pull-down Resistors are
Required Due to the Bus Hold on Data Inputs
● -40℃ to +125℃ Operating Temperature Range
● Available in a Green VSSOP-8 Package
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.
The active bus hold circuitry makes device unnecessary
to use external pull-up/pull-down resistors by holding
unused or floating data inputs at a valid logic level.

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
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.
