Logic Block Diagram
Product Description
Pericom Semiconductors PI74ALVTC series of logic circuits are
produced in the Companys advanced 0.35 micron CMOS tech-
nology, achieving industry leading speed.
The PI74ALVTC16240 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.
The device can be used as four 4-bit buffers, two 8-bit buffers, or
one 16-bit buffer. It provides inverting outputs and symmetrical
active-low output-enable (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-sink-
ing 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
inputs last state whenever the data input goes to high-impedance,
preventing floating inputs and eliminating the need for pullup/
down resistors.
