Fast CMOS
Registered Transceivers
Product Description:
Pericom Semiconductor’s PI29FCT series of logic circuits are produced in the Company’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.
