SN74HCS596DR

Shift Registers Overview

The SN74HCS596DR is an 8-bit serial-in, parallel-out shift register with a storage register, manufactured by Texas Instruments in the HCS logic family. It operates within a supply voltage range of 2 V to 6 V and supports ambient temperatures from -40°C to +125°C. The device features Schmitt-trigger inputs for noise immunity and provides open-drain outputs (QA-QH) requiring external pull-ups, alongside a push-pull serial output (QH'). It is housed in a 16-pin SOIC package.

Shift Registers Feature Summary

• Schmitt-trigger inputs provide high noise rejection and tolerance for slow input signal transitions.
• Open-drain parallel outputs allow flexible interfacing and wired-AND configurations when used with appropriate pull-up resistors.
• Separate clock inputs enable independent control of the shift register and the storage register operations.

Shift Registers Applications

• Output expansion for microcontroller systems
• LED matrix control circuits
• Seven-segment display control interfaces
• General-purpose 8-bit data storage

Shift Registers Procurement Notes

Verify that the ordering suffix 'D' corresponds to the SOIC-16 package as specified in the manufacturer's documentation. Confirm the component meets the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.

Shift Registers Selection Notes

Select this component when noisy environments require Schmitt-trigger input hysteresis or when open-drain outputs are necessary for level shifting or bus sharing. Ensure the design includes external pull-up resistors for the QA through QH outputs to achieve valid high logic states.

Shift Registers Part Context

This part belongs to the SN74HCS series, which utilizes balanced CMOS technology to offer low power consumption while maintaining robust drive capabilities. The HCS family is designed to replace older standard CMOS logic families, providing improved noise margins and wider operating voltage ranges suitable for modern embedded applications.
