Overview
The SN74HC4851QPWRQ1 is an automotive-grade analog switch and multiplexer manufactured by Texas Instruments. It functions as an 8:1 data selector housed in a 16-TSSOP package. The device operates within a supply voltage range of 2V to 6V and supports a maximum operating temperature of 125°C. Key electrical specifications include a maximum on-resistance of 195 ohms, channel-to-channel matching of 3 ohms, and a leakage current of 200nA. Switching times are rated at 78ns for both turn-on and turn-off conditions.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Configurable as an 8:1 multiplexer or single analog switch
- Low leakage current characteristics for signal integrity
Applications
- Automotive data acquisition systems requiring signal routing
- Multiplexing sensor inputs in vehicle control units
- Analog signal switching in automotive infotainment interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade for your target automotive application. Cross-reference the datasheet revision history to confirm material compliance and assembly site details before finalizing procurement orders.
Selection Notes
Select this component when an 8:1 multiplexing function is required in space-constrained automotive designs utilizing the TSSOP-16 footprint. Evaluate the 195-ohm on-resistance limit to ensure it meets the voltage drop requirements of your specific signal path. Confirm that the 2V to 6V supply range aligns with the system power architecture.
Part Context
This part belongs to the SN74HC4851-Q1 series of automotive logic ICs. It is designed specifically for harsh automotive environments, offering robust performance compared to standard commercial logic devices. The Q1 suffix indicates its qualification for automotive applications, distinguishing it from non-automotive variants within the broader HC logic family.
Replacement Considerations
Direct replacements must match the 16-TSSOP package and 8:1 multiplexer functionality. Verify that any substitute component maintains the same AEC-Q100 qualification level and compatible on-resistance specifications to ensure circuit compatibility without redesign.
