Overview
The MC74HCT4851ADR2G is an 8-to-1 multiplexer/demultiplexer from the onsemi 74HCT logic family, housed in a 16-SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 30 ns at 5 V. The device features LSTTL-compatible inputs and outputs, with a low static power consumption typical of CMOS technology. It is designed for high-speed data routing applications requiring robust noise immunity and reliable signal integrity across industrial temperature ranges.
Feature Summary
- LSTTL-compatible input and output interfaces ensure seamless integration with legacy TTL logic systems.
- High-speed switching capability with optimized propagation delay for efficient data routing.
- Low static power consumption characteristic of CMOS architecture reduces overall system energy usage.
Applications
- Data acquisition systems requiring analog or digital signal selection
- Communication equipment for channel selection and signal routing
- Industrial control panels for multiplexing sensor inputs
Procurement Notes
Verify the specific suffix 'R2G' confirms tape-and-reel packaging and RoHS compliance status directly from the manufacturer's latest documentation. Confirm the operating temperature range matches application requirements, as industrial variants may differ. Ensure the 16-SOIC footprint aligns with PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when LSTTL compatibility is required alongside CMOS low-power benefits. Compare against HC series if lower voltage operation (2V–6V) is needed, noting HCT is strictly 5V-tolerant. Verify that the 30 ns propagation delay meets timing constraints for the target clock speeds in the design.
Part Context
This part belongs to the 74HCT4851A family, which provides 8-channel multiplexing functionality. It shares pinout compatibility with other 74HC/HCT 4851 variants but differs in electrical characteristics due to the HCT input structure. The 'DWR2G' or 'ADR2G' suffixes indicate SOIC packaging and reel quantities, distinguishing it from TSSOP or DIP versions.
Replacement Considerations
MC74HC4851ADTR2G offers similar functionality but with HC input levels instead of LSTTL compatibility. SN74HCT4851N is a direct functional equivalent from Texas Instruments in a different package. Verify voltage tolerance and speed specifications when substituting with generic 74HCT4851 parts from other manufacturers.
