Product Description
Pericom Semiconductor聮s PI74FCT series of logic circuits are
produced in the Company聮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.
