Product Description
Pericom Semiconductor聮s PI74FCT series of logic circuits are
produced in the Company聮s advanced 0.6 micron CMOS tech-
nology, achieving industry leading speed grades.
The PI74FCT163374 is a 16-bit octal register designed with 16
D-type flip-flops with a buffered common clock and 3-state outputs.
The Output Enable (xOE) and clock (xCLK) controls are organized
to operate as two 8-bit registers or one 16-bit register. When OE is
HIGH, the outputs are in the high-impedance state. Input data
meeting the setup and hold time requirements of the D inputs is
transferred to the O outputs on the LOW-to-HIGH transition of the
clock input.
