Product Description
Pericom Semiconductor聮s PI29FCT series of logic circuits are pro-
duced in the Company聮s advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI29FCT52T and the PI29FCT53T are 8-bit registered transceivers
designed with two 8-bit back-to-back registers to store data flowing
in both directions between two bidirectional buses. Separate clock
enable and 3-state output enable signals are provided for each
register. The PI29FCT52T is a non-inverting option of the
PI29FCT53T.
