Overview
The SN74HC4852QDRQ1 is an automotive-grade analog switch manufactured by Texas Instruments. It integrates two independent 4-to-1 multiplexer circuits within a single 16-pin SOIC package. The device operates on a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +125°C. It is qualified under the AEC-Q100 standard for automotive applications. Key electrical characteristics include a maximum on-resistance of 195 ohms, a channel-to-channel matching of 3 ohms, and a typical turn-on time of 39ns with a turn-off time of 78ns. The off-state leakage current is limited to a maximum of 200nA.
Feature Summary
- Dual 4:1 multiplexer architecture providing flexible signal routing capabilities
- Automotive qualification ensuring reliability in harsh vehicle environments
- Low on-resistance with tight channel-to-channel matching for signal integrity
Applications
- Automotive sensor signal multiplexing
- Data acquisition systems in vehicles
- Communication interface switching
Procurement Notes
Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing process.
Selection Notes
Select this component when dual 4:1 multiplexing is required in space-constrained automotive designs. The 16-pin SOIC package offers a compact footprint compared to discrete solutions. Consider the 2V to 6V supply range compatibility with existing system power rails. Evaluate the 195-ohm on-resistance against the load impedance requirements of the signals being routed.
Part Context
This part belongs to the SN74HC4852 family of analog switches. The 'Q' suffix indicates automotive qualification, while 'D' specifies the SOIC package and 'RQ1' denotes the reel packaging and automotive grade. It complements other logic and switching devices in the Texas Instruments portfolio designed for robust automotive electronics.
Replacement Considerations
Check for direct pin-compatible alternatives within the same HCS or HC series that may offer different on-resistance or speed characteristics. Verify that any substitute maintains the AEC-Q100 qualification if automotive reliability is mandatory. Ensure the replacement package matches the 16-SOIC form factor for PCB compatibility.
