8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs
High−Performance Silicon−Gate CMOS
MC74HC595A, MC74HCT595A
The MC74HC595A/MC74HCT595A 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 device directly interfaces with the SPI serial data port on CMOS MPUs and MCUs. The MC74HC595A device inputs are compatible Standard CMOS outputs; with pullup resistors, they are compatible with TTL outputs.
