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 (A1, B1, C1 and D1) is presented to the inputs of the flip-flops, and when word select is high word 2  
(A2, B2, 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) = 19 ns typ (CL = 50 pF)  
High Output Current: Fanout of 10 LSTTL Loads  
Wide Operating Voltage: VCC = 2 to 6 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max
