Overview
The SN74HCS153QWBQBRQ1 is an automotive-grade dual 4-to-1 multiplexer featuring Schmitt-trigger inputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a WQFN-16 package. The device functions across an extended temperature range from -40 °C to +125 °C, ensuring reliability in demanding automotive environments.
Feature Summary
- Dual 4-to-1 data selection capability with independent channels
- Schmitt-trigger inputs for noise immunity and signal conditioning
- Automotive qualification compliant with AEC-Q100 standards
Applications
- Automotive data routing systems
- Signal selection in vehicle control units
- Multiplexing in automotive sensor interfaces
Procurement Notes
Verify the specific ordering suffix BQB corresponds to the WQFN-16 package configuration. Confirm that the component meets AEC-Q100 Grade 1 requirements for your specific application environment. Ensure compatibility with the intended operating voltage range of 2 V to 6 V during system design validation.
Selection Notes
Select this component when dual independent 4-to-1 multiplexing is required in space-constrained automotive designs. The WQFN-16 package offers a compact footprint suitable for high-density PCB layouts. Consider the Schmitt-trigger input characteristics if signal integrity or noise rejection is critical for the application.
Part Context
This part belongs to the SN74HCS153-Q1 series, designed specifically for automotive applications. It provides dual multiplexer functionality within a single integrated circuit, reducing component count compared to discrete solutions. The HCS logic family ensures robust performance under varying electrical conditions typical in automotive networks.
Replacement Considerations
SN74HCS153QPWRQ1 (TSSOP-16 package) and SN74HCS153DR1G4 (SOIC package) are alternative packaging options within the same functional family. Verify pinout compatibility and thermal performance differences when substituting packages.
