Product Description
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the Company’s advanced 0.6/0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI74FCT623T is an 8-bit wide non-inverting octal transceiver
designed with 3-state bus-driving outputs in both the send and
receive directions. Designed for asynchronous two-way operation
between data buses, the control function allows for maximum
flexibility in timing.
