HD74ACT298

This HD74ACT298 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 of HD74ACT298  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 (I₀ and I₁) and Select input (S) must be stable only one setup time prior to the HIGH-to-LOW transition of the clock for predictable operation.
