74HC298 Datasheet (Hitachi) - Quad. 2-input Multiplexers

74HC298, Quad. 2-input Multiplexers

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 wor
