SN74HC4851QPWRRB

Overview

The SN74HC4851QPWRRB is an automotive-grade, 8-channel CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features injection-current effect control to minimize signal distortion. The device provides one 8:1 channel configuration with a maximum propagation delay of 95 ns and a maximum on-resistance of 650 ohms. It supports operating temperatures from -40°C to +125°C and is housed in a TSSOP-16 package.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Injection-current effect control for improved signal integrity
Terminal compatibility with standard '4051 device functions

Applications

Automotive sensor signal routing
Data acquisition systems in vehicles
Analog switch applications requiring high reliability

Procurement Notes

Verify the complete part number including suffixes such as 'Q' for automotive qualification and 'PWRRB' for specific tape-and-reel packaging configurations. Confirm that the component meets AEC-Q100 Grade 1 requirements if used in harsh automotive environments. Ensure the ordering information matches the exact voltage and temperature specifications required for the target application design.

Selection Notes

Select this component when automotive certification is mandatory for analog switching applications. It is suitable for designs requiring terminal compatibility with legacy '4051 circuits while offering enhanced injection-current performance. Consider the TSSOP-16 package size and the 2 V to 6 V operating range when integrating into existing board layouts and power systems.

Part Context

This part belongs to the SN74HC4851 family of analog multiplexers. The 'Q' prefix denotes automotive qualification, distinguishing it from the standard commercial SN74HC4851. The 'RPWR' or 'PWRRB' suffix indicates the specific reel packaging format used for surface-mount assembly processes.

Replacement Considerations

The standard SN74HC4851PWR serves as a non-automotive functional equivalent but lacks AEC-Q100 certification. For direct automotive replacements, verify availability of SN74HC4851-Q1 variants. Ensure any substitute maintains the same TSSOP-16 footprint and injection-current control characteristics.
