SN74HCS153QDRQ1

Overview

The SN74HCS153QDRQ1 is an automotive-grade dual 4-to-1 multiplexer from Texas Instruments, featuring Schmitt-trigger inputs for noise immunity. It operates within a supply voltage range of 2 V to 6 V and supports data rates up to 105 MHz. The device is housed in a 16-pin SOIC package and is qualified under AEC-Q100 standards. It functions reliably across an extended temperature range from -40°C to +125°C, ensuring robust performance in demanding vehicular environments.

Feature Summary

• Dual independent 4-to-1 multiplexing capability with dedicated select lines
• Schmitt-trigger inputs provide enhanced noise filtering and signal integrity
• Automotive qualification ensures reliability under harsh operating conditions

Applications

• Automotive data routing and signal selection systems
• Vehicle electronic control unit (ECU) input management
• Infotainment system signal path switching

Procurement Notes

Verify the specific suffix 'QDRQ1' to confirm automotive grade and tape-and-reel packaging. Ensure compatibility with AEC-Q100 requirements for your target application. Cross-reference the datasheet for exact pinout and electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when dual channel multiplexing with high noise immunity is required in automotive designs. The Schmitt-trigger inputs are critical for noisy vehicle environments. Verify that the 2V to 6V supply range aligns with your system power architecture and that the SOIC-16 footprint fits your PCB layout constraints.

Part Context

This part belongs to the SN74HCSx series, which integrates Schmitt-trigger functionality into standard logic families. The 'Q' prefix denotes automotive qualification, while 'DRQ1' specifies the SOIC-16 package and reel packaging. It serves as a specialized variant designed for vehicular electronics requiring high reliability and noise tolerance.

Replacement Considerations

Check for direct equivalents such as the non-automotive SN74HCS153 or other dual 4-to-1 multiplexers with Schmitt triggers. Ensure any substitute meets the same AEC-Q100 qualification if automotive use is mandatory. Verify pin compatibility and electrical parameters before substitution.
