Overview
The MC74HC4851ADWR2G is an analog multiplexer/demultiplexer from the 74HC series, manufactured by onsemi. It features a single 8-to-1 circuit configuration housed in a 16-SOIC package with a width of 7.50mm. The device operates within a supply voltage range of 2V to 6V. Key electrical parameters include a maximum on-resistance of 400 ohms and a channel capacitance of 40pF. Maximum leakage current is specified at 100nA. It supports surface mount installation and functions across a temperature range of -55°C to +125°C.
Feature Summary
- Incorporates injection current effect control mechanisms to maintain signal integrity during switching operations.
- Provides high-speed analog signal routing capabilities suitable for data acquisition systems.
- Features low power consumption characteristics inherent to CMOS technology.
Applications
- Data acquisition systems requiring multi-channel signal selection
- Audio signal routing and switching applications
- Industrial process control instrumentation
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance status as specific manufacturing lots may vary. Check datasheet revisions for any pinout or electrical parameter updates prior to integration into final designs.
Selection Notes
Select this component when an 8-channel analog switch is required within the 74HC logic family specifications. Ensure the operating voltage remains between 2V and 6V. Consider the 400-ohm on-resistance limit for signal attenuation requirements. Verify thermal management needs for the -55°C to +125°C operating range.
Part Context
This part belongs to the MC74HC4851A family of analog multiplexers. It shares functional similarities with other 8:1 mux devices but is distinct due to its specific HC logic input compatibility and SOIC packaging. It serves as a direct replacement for legacy Motorola MC74HC4851 parts.
Replacement Considerations
MC74HC4851ADR2G is a verified substitute offering identical functionality in a tape-and-reel package format. Cross-reference with MC74HCT4851A if LSTTL-compatible inputs are required instead of standard HC levels.
