74LVC595A

8-bit serial-in/serial-out or parallel-out shift register; 3-state

The 74LVC595A is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks.

The input can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment.

This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

Data is shifted on the positive-going transitions of the SHCP input. The data in the shift 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 output (Q7S) for cascading purposes. It is also provided with asynchronous reset input MR (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 and benefits

  • 5 V tolerant inputs/outputs for interfacing with 5 V logic
  • Wide supply voltage range from 1.2 V to 3.6 V
  • CMOS low-power consumption
  • Direct interface with TTL levels
  • Balanced propagation delays
  • All inputs have Schmitt-trigger action
  • Complies with JEDEC standard JESD8-B/JESD36
  • ESD protection:
    • HBM JESD22-A114-D exceeds 2000 V
    • CDM JESD22-C101-C exceeds 1000 V
  • Specified from -40 °C to +85 °C and -40 °C to +125 °C

Applications

  • Serial-to-parallel data conversion
  • Remote control holding register
