Overview
The MC74HC4851ADTR2G is an 8-to-1 multiplexer/demultiplexer manufactured by onsemi, belonging to the 74HC logic family. It operates within a supply voltage range of 2V to 6V and features a maximum on-resistance of 400 ohms. The device utilizes a 16-TSSOP surface-mount package with a width of 4.40mm. Key electrical characteristics include a channel capacitance of 40pF and a maximum leakage current of 100nA. It supports a wide operating temperature range from -55°C to +125°C.
Feature Summary
- Provides 8:1 multiplexing or demultiplexing functionality in a single circuit configuration
- Features low on-resistance for efficient signal transmission across the specified voltage range
- Designed for high-speed digital applications with controlled leakage and capacitance parameters
Applications
- Data acquisition systems requiring signal routing
- Communication equipment for channel selection
- Industrial control systems utilizing multi-channel input/output switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability. Ensure the part number suffix matches the required tape and reel quantity specifications for production integration.
Selection Notes
Select this component when an 8-channel analog or digital switch is required within a 2V to 6V operational window. The 16-TSSOP package suits space-constrained designs. Consider the 400-ohm on-resistance and 40pF capacitance limits against signal integrity requirements for the target frequency range.
Part Context
This part belongs to the MC74HC4851A series of multiplexers. It shares functional similarities with other HC family logic devices but is distinct in its 8:1 switching topology. The ADTR2G suffix indicates the specific TSSOP-16 packaging and tape-and-reel delivery format used by onsemi.
Replacement Considerations
Compatible substitutes include MC74HC4851ADWR2G and MC74HC4851ADR2G, which offer identical logical functions. Verify pin compatibility and package dimensions before substitution to ensure mechanical fit within the existing PCB layout.
