Description
Pericom Semiconductor’s PI74VCX16244 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 true 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 Vcc through a pullup resistor; the minimum
value of the resistor is determined by the current-sinking capability
of the driver.
The PI74VCX family is I/O Tolerant, allowing it to operate in
1.8/3.6V systems.
