Overview
The SN74HC4852DR is a dual 4-to-1 multiplexer switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2V to 6V. The device features two independent SP4T circuits within a 16-SOIC package. Key electrical parameters include a maximum on-resistance of 195 ohms and a channel-to-channel matching of 3 ohms. Switching times are specified with a maximum Ton of 39ns and Toff of 78ns. Leakage current (IS(off)) is limited to 200nA, while channel capacitance is 22pF. It supports an operating temperature range of -40°C to +125°C.
Feature Summary
- Dual independent 4-to-1 multiplexing configuration
- High-speed switching capabilities for signal routing
- Low leakage current for efficient power management
Applications
- Data source selection in digital systems
- Signal routing in communication interfaces
- Multiplexing applications requiring low distortion
Procurement Notes
Verify the specific suffix 'DR' indicates the SOIC package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the datasheet revision date to ensure compatibility with design specifications.
Selection Notes
Select this component for designs requiring dual 4:1 mux functionality within a standard logic family. Compare on-resistance values against load requirements to ensure signal integrity. Verify voltage levels match the system's single supply constraints. Consider package thermal performance for high-density PCB layouts.
Part Context
This part belongs to the SN74HC4852 family of analog switches. It is functionally similar to other HC-series multiplexers but offers specific pinout and electrical characteristics defined by Texas Instruments. It serves as a direct replacement for legacy discrete switching solutions in compact digital designs.
Replacement Considerations
The SN74HC4852DGVGR is a compatible alternative offering the same functionality in a TVSOP package. Check pin compatibility and package dimensions before substitution. Verify that electrical parameters such as on-resistance and switching speeds meet the original design requirements.
