Description

Pericom Semiconductor’s PI74LPT series of logic circuits are pro-

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

achieving industry leading speed grades.

The PI74LPT573 is an 8-bit transparent latch designed with

3-state outputs and is intended for bus oriented applications. When

Latch Enable (LE) is HIGH, the flip-flops appear transparent to the

data. The data that meets the set-up time when LE is LOW is latched.

When OE is HIGH, the bus output is in the high impedance state.

The PI74LPT573 can be driven from either 3.3V or 5.0V devices

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

3.3/5.0V system.
