DM74LS298
Functional Description
This device is a high speed quad 2-port register. 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 output register is fully edge-triggered. The Data inputs (Inx) and Select input (S)
need be stable only one setup time prior to the HIGH-to-LOW transition of the clock for predictable operation.
