74LV595
Datasheet
General description
The 74LV595 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT595.
The74LV595 is an 8-stage serial shift register with a storage register and 3-State outputs. The shift register and storage register have separate clocks.
Data is shifted on the positive-going transitions of the SHCP input. The data in each register is transferred to the storage register on a positive-going transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register.
The shift register has a serial input (DS) and a serial standard output (Q7?) all for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages. The storage register has 8 parallel 3-State bus driver outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.
Features
- Optimized for Low Voltage applications: 1.0V 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
- 8-bit serial input
- 8-bit serial or parallel output
- Storage register with 3-State outputs
- Shift register with direct clear
- Output capability:
parallel outputs; bus driver
serial output; standard - ICC category: MSI
