HD74HC78
HD74HC78 is Dual J-K Flip-Flops manufactured by Renesas.
Description
This flip-flop is edge sensitive to the clock input and change state on the negative transition of the clock pulse. Each flip-flop has independent J, K, and preset inputs and Q and Q outputs. Two flip-flops are controlled by a mon clear and a mon clock. Preset and clear are independent of the clock and acplished by a low logic level on the corresponding input.
Features
- High Speed Operation: tpd (Clock to Q) = 20 ns typ (CL = 50 p F)
- 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) = 2 µA max (Ta = 25°C)
