The single-element, 8-bit architecture means one shift register per package, with the output register holding the parallel data while the shift register accepts the next byte. ## Supply voltage and temperature — fit for industrial logic rails Rated for 2V to 6V supply, the SN74HC594DR spans 3.3V and 5V logic families without a level translator. ## Package and rework — 16-SOIC The 1.27 mm pitch gives good visual access for inspection and touch-up. No exposed pad, so thermal management is straightforward — just standard board mounting.","metaTitle":"SN74HC594DR Shift Register, 8-Bit, 2V-6V, 16-SOIC","metaDescription":"TI SN74HC594DR 8-bit serial-to-parallel shift register with push-pull outputs.
