SN74HC151QDRG4Q1

Overview

The SN74HC151QDRG4Q1 is an automotive-grade, 8-line to 1-line data selector or multiplexer manufactured by Texas Instruments. It belongs to the SN74HC-Q1 series of wide-bandgap logic devices, designed for robust performance in demanding environments. The component operates within a supply voltage range of 2 V to 6 V and supports a maximum propagation delay of 30 ns at 6 V with a 50 pF load. It features complementary outputs (Y and W) and includes a strobe input for enabling or disabling the selected data path. The device is housed in a 16-pin SOIC package and is qualified to AEC-Q100 standards.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications
• Wide operating voltage range supporting 2 V to 6 V power supplies
• Provides complete binary decoding to select one of eight data sources
• Includes active-low strobe input to disable outputs when not in use

Applications

• Data selection and routing in automotive electronic control units
• Parallel-to-serial data conversion systems
• Boolean function generation circuits
• Industrial process control signal multiplexing

Procurement Notes

Verify that the specific part number suffix matches the required automotive grade and packaging configuration. Confirm that the device meets the necessary AEC-Q100 reliability targets for your specific application environment. Ensure compatibility with your system's voltage levels and signal integrity requirements before finalizing procurement decisions.

Selection Notes

Select this component when an 8-channel multiplexer with automotive certification is required. It is suitable for designs needing low power consumption and high noise immunity within the HC logic family. Consider the 16-pin SOIC package constraints and thermal characteristics during PCB layout planning.

Part Context

This device is part of the SNx4HC-Q1 family, which extends the standard 74HC logic functionality to meet automotive industry requirements. The Q1 designation indicates compliance with strict automotive quality and reliability standards, distinguishing it from commercial-grade counterparts while maintaining similar electrical performance characteristics.

Replacement Considerations

Direct substitutes include other SN74HC151 variants with automotive qualification such as SN74HC151QDRQ1. Verify pinout compatibility and electrical specifications before swapping components.
