Quadruple 2-Input Multiplexer with Storage and Negative-Edge Clock
X74_298 selects 4-bits of data from two sources (D1 – A1 or D2 – A2) under the control of a common word select input (WS). When WS is Low, D1 – A1 is chosen, and when WS is High, D2 – A2 is chosen. The selected data is transferred into the output register (QD – QA) during the High-to-Low transition of the negative-edge triggered clock (CK).
