HD74HC574
Description
These devices are positive edge triggered flip-flops. The difference between HD74HC564 and HD74HC574 is only that the former has inverting outputs and the latter has noninvertering outputs.
Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or Q outputs on positive going transitions of the clock (CK) input. When a high logic level is applied to the output control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
Features
- High Speed Operation: tpd (Clock to Output) = 13 ns typ (CL = 50 p F)
- High Output Current: Fanout of 15 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 (Ta = 25°C)
- Ordering Information
