Overview
HD74HC298
Quad.
2-input Multiplexers (with storage)
Description
This circuit is controlled by the signals word select and clock.
When the word select input is taken low word 1 (A 1, B1, C1 and D 1) is presented to the inputs of the flip-flops, and when word select is high word 2 (A 2, B 2, C2 and D2) is presented to the inputs of the flip-flops.
The selected word is clocked to the output terminals on the negative edge of the clock pulse.
