PI74ALVTC16245
16-Bit BiDirectional Transceiver
with 3-State Outputs
Features
Description
• PI74ALVTC family is designed for low voltage operation,
VDD = 1.8V to 3.6V
PericomSemiconductor’sPI74ALVTC16245isa16-bitbidirectional
transceiver designed for asynchronous two-way communication
between data buses. The direction control input pin (xDIR)
determines the direction of data flow through the bidirectional
transceiver.TheDirectionandOutputEnablecontrolsaredesigned
to operate this device as either two independent 8-bit transceivers
orone16-bittransceiver.Theoutputenable(OE)input,whenHIGH,
disables both A and B ports by placing them in Hi-Z condition.
• Supports Live Insertion
• 3.6V I/O Tolerant Inputs and Outputs
• Bus Hold
• High Drive, -32/64mA @ 3.3V
• Uses patented noise reduction circuitry
• Power-off high impedance inputs and outputs
• Industrial operation at –40°C to +85°C
• Packaging(Pb-free&Greenavailable):
–48-pin240-milwideplasticTSSOP(A)
–48-pin173-milwideplastic TVSOP(K)
–48-pin300-milwideplastic SSOP(V)
To ensure the high-impedance state during power up or power
down, OE should be tied to Vdd through a pullup resistor; the
minimumvalueoftheresistorisdeterminedbythecurrent-sinking
capability of the driver.
The family offers both I/O Tolerant, which allows it to operate in
mixed 1.8/3.6V systems, and “Bus Hold,” which retains the data
input’s last state whenever the data input goes to high-impedance,
preventing “floating” inputs and eliminating the need for pullup/
down resistors.

Supply Voltage Range, VDD.......................................... –0.5V to 4.6V
Input Voltage Range, VI ................................................. -0.5V to 4.6V
Output Voltage Range, VO (3-Stated) ............................ -0.5V to 4.6V
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions above those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect reliability.
