HD74AC298/HD74ACT298

Quad 2-Input Multiplexer with Storage

Description

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 register is fully edge

triggered. The Data inputs (I

HIGH-to-LOW transition of the clock for predictable operation.
