HD74ACT298 Datasheet (Hitachi Semiconductor) - Quad 2-Input Multiplexer with Storage

HD74ACT298, Quad 2-Input Multiplexer with Storage

This device is a high-speed multiplexer with storage.

It selects four bits of data from two sources (Ports) under the control of a common Select input (S).

The selected data is transferred to the 4-bit output register synchronous with the HIGH-to-LOW transition of the Clock input ( CP ).

The 4-bit r
