Product Description
Pericom Semiconductor's PI74FCT series of logic circuits are produced in the Company's advanced 0.6 micron CMOS technology, 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.

Notes: 1. Propagation Delays and Enable/Disable times are with Vcc = 3.3V 0.3V, normal range. For Vcc = 2.7V, extended range, all Propagation Delays and Enable/Disable times should be degraded by 20%. 2. See test circuit and wave forms. 3. Minimum limits are guaranteed but not tested on Propagation Delays. 4. This parameter is guaranteed but not production tested. 5. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
