SN74HCS596QPWRQ1

Shift Registers Overview

The SN74HCS596QPWRQ1 is an automotive-grade, 8-bit serial-in/parallel-out shift register with a storage register. It operates within a supply voltage range of 2 V to 6 V and features Schmitt-trigger inputs for noise rejection. The device provides open-drain parallel outputs (QA-QH) requiring external pull-ups and a push-pull serial output (QH'). It includes separate clocks for the shift register (SRCLK) and storage register (RCLK), along with a direct overriding clear input (SRCLR). Packaged in a TSSOP-16 format.

Shift Registers Feature Summary

• Schmitt-trigger inputs provide low power noise rejection and support slow or noisy input signals.
• Open-drain parallel outputs allow flexible voltage translation and wired-AND configurations.
• Separate clocking architecture enables independent control of data shifting and storage operations.

Shift Registers Applications

• Output expansion
• LED matrix control
• 7-segment display control
• 8-bit data storage

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SN74HCS596-Q1 family includes both TSSOP and SOIC variants. Confirm that the component meets AEC-Q100 Grade 1 qualification requirements for your target automotive temperature range. Ensure design compliance with absolute maximum ratings regarding supply voltage and current limits during procurement validation.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with open-drain outputs is required for automotive environments. The HCS logic family supports wide voltage operation from 2 V to 6 V. Consider the separate SRCLK and RCLK pins if glitch-free data transfer between the shift and storage registers is necessary. Verify that the open-drain nature of QA-QH aligns with the system's pull-up resistor strategy.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74HCS596-Q1 family of automotive logic devices. It is designed for high-reliability applications requiring robust signal integrity. The Q1 designation indicates automotive qualification, while the HCS series denotes CMOS technology with Schmitt-trigger inputs for enhanced noise immunity compared to standard HC logic families.
