HD74HC298
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 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.
Key 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
