SN74HCS151QDRQ1

Overview

The SN74HCS151QDRQ1 is an automotive-grade 8-to-1 data selector/multiplexer from Texas Instruments, belonging to the SN74HCS logic series. It features Schmitt-trigger inputs for noise immunity and operates within a supply voltage range of 2 V to 6 V. The device provides one output and supports propagation delays as low as 5 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Schmitt-trigger inputs enhance noise rejection capabilities
• Wide operating voltage range supporting 2 V to 6 V systems
• Extended temperature operation suitable for harsh environments

Applications

• Automotive data routing systems
• Signal selection in vehicle electronics
• Multiplexing in automotive control modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm AEC-Q100 qualification status and package integrity upon receipt. Ensure storage conditions align with moisture sensitivity levels specified in the datasheet. Cross-reference ordering part numbers to match exact suffix requirements for automotive grade specifications.

Selection Notes

Select this component when automotive reliability and noise immunity are critical. The HCS series offers faster switching speeds compared to standard HC logic. Verify that the 2 V to 6 V supply range matches the target system design. Consider the SOIC-16 package dimensions for PCB layout compatibility.

Part Context

This multiplexer belongs to the SN74HCS family, which integrates Schmitt-trigger functionality into high-speed CMOS technology. The QDRQ1 suffix indicates automotive qualification and specific packaging options. It serves as a robust solution for signal routing in demanding automotive environments where signal integrity is paramount.

Replacement Considerations

SN74HC151QDRQ1 is a related variant but lacks Schmitt-trigger inputs. SN74HCS151PWRQ1 shares the same logic family but differs in package type. Verify functional equivalence and pinout compatibility before substitution.
