Detailed Description

8-bit serial-in, serial or parallel-out shift register with storage latch and tri-state parallel outputs. Wide supply range 2.0 to 5.5 V, industrial temperature grade -40 to 85°C, surface-mount 16-SOIC package. Designed for easy expansion of MCU or FPGA GPIO pins and for cascading multiple registers through QH’ serial out. RoHS3 compliant

Key Features

8-bit shift register plus 8-bit storage latch for stable outputs during shifting

Serial in to parallel out, with serial out for easy cascading

Tri-state outputs allow bus sharing and isolation when needed

Output enable pin and asynchronous master reset pin

Wide supply range 2.0 to 5.5 V for 3.3 V or 5 V systems

Industrial operating temperature range -40 to 85°C

74LV family, low power CMOS

Standard pinout compatible with the popular 74x595 register family

Surface-mount 16-SOIC with 3.90 mm body width

Tape and Reel packaging for automated assembly

RoHS3 compliant

Key Advantages

Frees up MCU pins by converting a few serial lines into many parallel outputs

Easy to daisy-chain for more outputs without extra MCU pins

Works across common logic rails 3.3 V and 5 V for flexible design-in

Tri-state outputs simplify sharing lines with other devices

Mature, widely used function with broad ecosystem and software examples

Compact SOIC footprint fits dense boards and standard SMT processes
