SN74AC596PWRQ1

Shift Registers Overview

The SN74AC596PWRQ1 is an automotive-grade, 8-bit serial-in, parallel-out shift register with open-drain outputs. It operates within a supply voltage range of 1.5V to 6V and supports temperatures from -40°C to +125°C. The device features separate clocks for the shift and storage registers, a direct overriding clear input, and a push-pull serial output for cascading. It provides continuous ±24mA output drive at 5V and supports up to ±75mA in short bursts.

Shift Registers Feature Summary

• AEC-Q100 qualified for automotive applications
• Wide operating voltage range from 1.5V to 6V
• Open-drain parallel outputs with high current drive capability
• Push-pull serial output for cascading

Shift Registers Applications

• Increasing microcontroller output count
• Temporary data storage
• Seven-segment display control

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the PW suffix indicates a TSSOP-16 package. Confirm that the wettable flank feature is not required for this specific package variant. Ensure the component meets AEC-Q100 Grade 1 requirements for your target temperature range. Validate ESD classification levels against system design constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when an automotive-qualified shift register with open-drain outputs is required. It is suitable for applications needing wide voltage compatibility between 1.5V and 6V. Consider the TSSOP-16 package if surface-mount assembly is preferred over QFN. Ensure the design accounts for the open-drain nature of the parallel outputs, requiring external pull-up resistors for high logic states.

Shift Registers Part Context

This part belongs to the SN74AC596-Q1 family of automotive 8-bit shift registers. It shares functional characteristics with other members of the series but differs in packaging. The PW suffix specifically denotes the TSSOP-16 package option, distinguishing it from the WQFN variants available in the same product line.
