Overview
The SN74HC4852DRG4 is a dual 4-to-1 multiplexer/demultiplexer switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2V to 6V. The device features two independent circuits, each configured as a 4:1 mux or demux. 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, and channel capacitance is 22pF. It is housed in a 16-TVSOP package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Dual independent 4-to-1 multiplexer or demultiplexer configuration
- Low on-resistance for signal integrity preservation
- High leakage resistance for effective isolation when off
- CMOS technology compatible with standard logic families
Applications
- Data acquisition systems requiring signal routing
- Communication equipment for line selection
- Industrial control systems for sensor switching
- Test and measurement instruments
Procurement Notes
Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm compliance with RoHS3 directives and material declarations. Ensure the package type matches the design footprint requirements. Cross-reference the part number with official distributors to confirm current availability status and lead times, as stock levels fluctuate. Confirm that the voltage ratings align with the target application's power supply constraints before finalizing procurement.
Selection Notes
Select this component when a dual 4:1 switching function is required within a compact surface-mount package. Consider the 195-ohm on-resistance limit for signal loss calculations in high-impedance circuits. Verify that the 2V to 6V supply range fits the system architecture. Compare switching speeds against the application's timing requirements, noting the 78ns maximum turn-off time. Ensure thermal management capabilities support the -40°C to 85°C operating range.
Part Context
This part belongs to the SN74HC4852 family of analog switches. It is functionally equivalent to the SN74HC4852DGVR variant but may differ in packaging or reel specifications. The 'DR' indicates a SOIC-style tape and reel package, while 'G4' denotes environmental compliance. It serves as a solution for routing multiple signals through a single path in digital and mixed-signal systems.
Replacement Considerations
Publicly confirmed substitute part numbers include SN74HC4852DGVR. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in package dimensions or thermal characteristics. Consult the manufacturer's cross-reference guide for additional alternatives if the primary substitute is unavailable.
