SN74HCS595QDRQ1

Shift Registers Overview

The SN74HCS595QDRQ1 is an automotive-grade, 8-bit serial-in, parallel-out shift register with a D-type storage register. 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 balanced CMOS 3-state outputs capable of ±7.8 mA drive current at 6 V. It is housed in a 16-pin SOIC package.

Shift Registers Feature Summary

• AEC-Q100 qualified for automotive applications
• Schmitt-trigger inputs eliminate erroneous outputs from slow-edged or noisy signals
• Balanced CMOS 3-state outputs allow high-impedance states

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 'D' corresponds to the SOIC-16 package variant. Confirm AEC-Q100 qualification status matches project requirements. Ensure input signal levels remain within the specified absolute maximum ratings to prevent damage. Check thermal resistance values against system cooling capabilities.

Shift Registers Selection Notes

Select this component when automotive reliability and wide voltage operation are required. The Schmitt-trigger architecture is suitable for environments with significant electrical noise. The separate clocks for shift and storage registers facilitate independent data loading and output updating without interference.

Shift Registers Part Context

This part belongs to the SN74HCS595-Q1 family of automotive logic devices. It shares functional characteristics with other members of the series but differs in packaging options such as TSSOP, WQFN, and SOT-23-THN. The QDRQ1 designation specifically identifies the SOIC-16 package configuration.

Shift Registers Replacement Considerations

SN74HCS595PW-Q1 (TSSOP), SN74HCS595BQB-Q1 (WQFN), SN74HCS595DYY-Q1 (SOT-23-THN). Verify pinout compatibility and thermal performance before substitution.
