Overview
The SN74HC4852QPWRQ1 is an automotive-grade analog switch manufactured by Texas Instruments. It features a dual 4:1 multiplexer structure housed in a 16-pin TSSOP package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +125°C. Key electrical parameters include a maximum on-resistance of 195 ohms, channel-to-channel matching of 3 ohms, and a leakage current of 200 nA. It is qualified under AEC-Q100 standards for automotive applications.
Feature Summary
- Dual 4:1 multiplexer configuration for signal routing
- Automotive qualification compliant with AEC-Q100 standards
- Low on-resistance with tight channel-to-channel matching
- Wide operating voltage and temperature ranges
Applications
- Automotive data acquisition systems
- Signal multiplexing in vehicle control units
- Battery management system monitoring
Procurement Notes
Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets the required AEC-Q100 reliability grades for your specific automotive application environment before finalizing procurement.
Selection Notes
Select this component when a dual 4:1 analog switching solution is required for automotive environments. Ensure the input signals remain within the 2 V to 6 V supply range. Consider the 195-ohm on-resistance and 200-nA leakage current limits to verify compatibility with your signal integrity requirements.
Part Context
This part belongs to the SN74HC485x-Q1 family of automotive analog switches. It shares the same logical architecture as the SN74HC4851-Q1 but provides two independent 4:1 multiplexers instead of a single 8:1 mux. Both devices utilize the 16-TSSOP package and share similar electrical characteristics regarding on-resistance and leakage.
Replacement Considerations
The SN74HC4851QPWRQ1 serves as a functional substitute if a single 8:1 multiplexer topology is acceptable. Verify pinout compatibility between the 4:1 dual configuration and the 8:1 single configuration to ensure proper circuit integration.
