SN74HC594DR Description

Short technical summary and product information.

The SN74HC594DR is an 8-bit shift register manufactured by Texas Instruments. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. It operates over a wide voltage range of 2 V to 6 V and is designed for surface mount applications in a 16-SOIC package.

 

Key features include independent clocks for both the shift and storage registers, as well as independent direct overriding clears. The parallel outputs (QA–QH) have high-current capability, and a serial output (QH’) is provided for cascading purposes. The operating temperature range is -40°C to 85°C.

 

This shift register is suitable for various applications, including pro audio mixers, elevators, escalators, human machine interfaces, and entertainment systems. Its robust design and wide operating parameters make it a versatile component for digital logic designs.
