74LV574
Datasheet
General description
The 74LV574 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT574.
The 74LV574 is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops.
The eight flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition.
When OE is LOW, the contents of the eight flip-flops is available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.
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 at VCC = 3.3VTamb = 25°C
- Typical VOHV (output V OH undershoot) > 2V at VCC = 3.3VTamb = 25°C
- Common 3-State output enable input
- Output capability: bus driver
- ICC category: MSI
