Overview
The SN74HC4851PWRG4 is an eight-channel CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features injection-current effect control, allowing signals at disabled channels to exceed the supply voltage without affecting the enabled channel. The device utilizes a 16-pin TSSOP package with dimensions of 5mm x 6.4mm. Key electrical parameters include a maximum on-state resistance (Ron) of 670Ω at 2V and 345Ω at 3.3V. Propagation delay (tPD) ranges from 19.5ns at 2V to 13.5ns at 5V. Off-state leakage current (IS(OFF)) is typically ±0.5µA at 5V.
Feature Summary
- Injection-current effect control prevents signal interference when disabled channel voltages exceed the supply rail.
- Terminal compatible with SN74HC4051, SN74LV4051A, and CD4051B devices for direct pin-to-pin replacement.
- Low crosstalk between switches ensures high signal integrity in multiplexing applications.
Applications
- Analog and digital multiplexing and demultiplexing
- Diagnostics and monitoring systems
- Data center switch infrastructure
- Remote radio unit (RRU) implementations
- Electricity metering equipment
Procurement Notes
Verify the ordering suffix 'G4' indicates compliance with RoHS standards and absence of halogenated flame retardants. Confirm the package type matches the required 16-TSSOP footprint. Ensure the operating temperature range aligns with the specified -40°C to 125°C ambient limits. Check for any specific material declarations or REACH status updates in the latest documentation.
Selection Notes
Select this component when terminal compatibility with legacy '4051 devices is required alongside improved injection-current handling. Consider the 2V to 5.5V supply range for low-voltage logic interfaces. Evaluate the on-state resistance specifications against the load requirements to ensure acceptable signal attenuation. Verify that the 16-pin TSSOP package fits the available PCB real estate.
Part Context
This part belongs to the SN74HC4851 family of 8-channel analog multiplexers. The 'G4' suffix denotes Green/RoHS-compliant manufacturing. It serves as a modern CMOS alternative to older bipolar technologies, offering lower power consumption while maintaining functional equivalence to standard '4051 series parts.
Replacement Considerations
Direct replacements include SN74HC4851PW, SN74HC4851PWR, and SN74HC4851PWRE4. These variants share identical functionality and pinouts but may differ in packaging format or environmental compliance markings.
