Product Description:

Pericom Semiconductor’s PI74FCT series of logic circuits are produced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading speed grades.

The PI74FCT16841T and PI74FCT162841T are 20-bit wide transparent latches designed to provide temporary storage of data and can be used as I/O ports, memory address latches, and bus drivers. The Output Enable and Latch Enable controls allow the devices to be operated as two 10-bit latches or one 20-bit latch. Signal pins are arranged in a flow-through organization for ease of layout and hysteresis is designed into all inputs to improve noise margin.
