Description
74HC595 8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs
The 74HC595 consists of an 8−bit shift register and an 8−bit D−type latch with three−state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also
provides parallel data to the 8−bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register.
The HC595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.
