Product Description

Pericom Semiconductor’s PI74LCX series of logic circuits are

produced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

The PI74LCX16240 is an inverting 16-bit buffer/line driver designed

for applications driving high-capacitance loads and low impedance

backplanes. This high-speed, low power device offers bus/backplane

interface capability and a flow-through organization for ease of

board layout. This device is designed with three-state controls to

operate in a Quad-Nibble, Dual-Byte, or a single 16-bit word mode.

The PI74LCX16240 can be driven from either 3.3V or 5.0V devices

allowing this device to be used as a translator in a mixed

3.3V/5.0V system.
