74595 8-Bit Serial to Parallel Shift Register IC (74HC595AL)

Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 μA
High Noise Immunity Characteristic of CMOS Devices

The 74595 is identical in pinout to the HS/LS/ALS595. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The 74595 consists of an 8-bit shift register and an 8-bit Dtype 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.
