PI74ALVTC16241
16-Bit Buffer/Driver
with 3-State Outputs
Product Features
Product Description
PI74ALVTCfamilyisdesignedforlowvoltageoperation,
Pericom Semiconductor’s PI74ALVTC series of logic circuits are
produced in the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
VDD = 1.8V to 3.6V
Supports Live Insertion
The PI74ALVTC16241 buffer/driver is designed specifically to
improve both the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented receivers and
transmitters.
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
Packages available:
Thedevicecanbeusedasfour4-bitbuffers,two8-bitbuffers,orone
16-bit buffer. It provides true outputs and complementary active-
low output-enable (OE and OE) inputs.
To ensure the high-impedance state during power up or power
down, OE should be tied to Vdd through a pullup resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
48-pin240milwideplasticTSSOP(A)
48-pin173milwideplasticTVSOP(K)
48-pin300milwideplasticSSOP(V)
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
inputs last state whenever the data input goes to high-impedance,
preventing floating inputs and eliminating the need for pullup/
down resistors.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
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.
