Serial-in shift registers with output registers - SN74LS595

SN74LS595 (ACTIVE)

Serial-in shift registers with output registers

 

Description

These devices each contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state ('LS595) or open-collector ('LS596) outputs. Separate clocks are provided for both the shift register and the storage register. The shift register has a direct-overriding clear, serial input, and serial output pins for cascading.

Both the shift register and storage register clocks are positive-edge triggered. If the user wishes to connect both clocks together, the shift register state will always be one clock pulse ahead of the storage register.

 

Features

  • 8-Bit Serial-In, Parallel-Out Shift Registers with Storage
  • Choice of 3-State ('LS595) or Open-Collector ('LS596) Parallel Outputs
