SN74HC4851QDRG4Q1

Overview

The SN74HC4851QDRG4Q1 is a single 8-to-1 multiplexer from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It operates within a supply voltage range of 2V to 6V and features a maximum on-resistance of 195 ohms with a channel-to-channel matching of 3 ohms. The device supports switching times of up to 78ns for both turn-on and turn-off phases. It utilizes a 16-SOIC package with a width of 0.154 inches (3.90mm) and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

AEC-Q100 qualified for automotive reliability requirements
Single 8:1 multiplexer configuration in a compact SOIC package
Extended operating temperature range suitable for harsh environments

Applications

Automotive data acquisition systems
Vehicle sensor signal routing
In-car infotainment input selection

Procurement Notes

Verify the complete part number including the Q1 suffix to ensure automotive grade compliance. Confirm the G4 suffix indicates lead-free and RoHS-compliant manufacturing. Check the DRG4 designation for the specific SOIC-16 package variant. Ensure the source document matches the manufacturer's official datasheet for the SN74HC4851-Q1 series to avoid counterfeit components.

Selection Notes

Select this component when an 8-channel multiplexing function is required in automotive electronics. The 2V to 6V supply range accommodates various vehicle power architectures. The 195-ohm on-resistance is suitable for general-purpose signal switching rather than high-current applications. Compare against non-qualified HC4851 variants if automotive durability is not required.

Part Context

This part belongs to the SN74HC4851-Q1 family of automotive-grade analog switches. It shares functional compatibility with the commercial SN74HC4851 but meets stricter automotive reliability standards. The QDRG4 suffix denotes the specific tape-and-reel packaging and lead-free composition for surface-mount assembly.
