Product details

8-bit shift register with push-pull outputs — 2V to 6V supply

It accepts serial data and outputs parallel data through push-pull stages, making it a straightforward choice for GPIO expansion, LED segment driving, or control-signal latching in 2V to 6V logic systems. 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.

Frequently asked questions

Is SN74HC594DR pin compatible with SN74HC595?

The SN74HC594DR and SN74HC595 share the same 16-SOIC footprint and basic shift-register function, but their output structures differ: the 594 has push-pull outputs with an output-enable control, while the 595 uses three-state outputs. Check the respective datasheet pin assignments before substituting — they are not drop-in replacements without reviewing the output-stage logic.

Is SN74HC594DR obsolete or active?

It remains available for new designs and production.
