CY74FCT399T Overview
The CY74FCT399T is a high-speed quad 2-input register that selects four bits of data from either of two sources (ports) under control of a mon select (S) input. Selected data are transferred to a 4-bit output register synchronous with the low-to-high transition of the clock (CP) input. The 4-bit D-type output register is fully edge triggered.
