Product Description

Pericom Semiconductor’s PI74FCT series of logic circuits are

produced in the Company’s advanced 0.6 micron CMOS

technology, achieving industry leading speed grades.

The PI74FCT162344T is an address/clock driver designed to

provide the ability to fanout to memory arrays. Eight banks, each

with a fanout of four, and 3-state control, provide efficient address

distribution. One or more banks may be used for clock distribution.

The PI74FCT162344T has 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.
