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 PI74FCT163373 is a 16-bit transparent latch designed with 3-state outputs and are intended for bus oriented applications. The Output Enable and Latch Enable controls are organized to operate as two 8-bit latches or one 16-bit latch. When Latch Enable (LE) is HIGH, the flip-flops appear transparent to the data. The data that meets the set-up time when LE is LOW is latched. When OE is HIGH, the bus output is in the high impedance state.

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.
