74HC595DTR2G

Shift Registers Overview

The onsemi 74HC595DTR2G is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs. It consists of an 8-bit shift register and an 8-bit D-type latch with independent clock inputs. The device operates within a voltage range of 2.0 to 6.0 V and supports an operating temperature from -55°C to +125°C. It features asynchronous reset, low input current, and high noise immunity. The component is housed in a TSSOP-16 package.
