74LV74
Datasheet
General description
The 74LV74 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT74.
The 74LV74 is a dual positive edge triggered, D-type flip-flop with individual data (D) inputs, clock (CP) inputs, set (SD) and (RD) inputs; also complementary Q and Q outputs.
The set and reset are asynchronous active LOW inputs and operate independently of the clock input. Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse. The D inputs must be stable one set-up time prior to the LOW-to-HIGH clock transition, for predictable operation.
Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
Features
- Wide operating voltage: 1.0 to 5.5V
- Optimized for Low Voltage applications: 1.0 to 3.6V
- Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V
- Typical VOLP (output ground bounce) < 0.8V @ VCC = 3.3VTamb = 25°C
- Typical VOHV (output V OH undershoot) > 2V @ VCC = 3.3VTamb = 25°C
- Output capability: standard
- ICC category: flip-flops
