Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced 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.
The output buffers on the PI74FCT16841T and PI74FCT162841T
are especially designed for driving high-capacitance loads and low
impedance backplanes and include a Power-Off Disable function
allowing “live insertion” of boards when the devices are used as
backplane drivers.
The PI74FCT162841T has ±24 mA balanced output drivers. It is
designed with current limiting resistors at its outputs to control the
output edge rate resulting in lower ground bounce and undershoot.
This eliminates the need for external terminating resistors for most
interface applications.
