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. Features • • • • • High Speed Operation: tpd (Clock to Q.
