Overview
The MC74HCT4852ADR2G is a dual 4-to-1 multiplexer/demultiplexer from the onsemi HCT logic family, housed in a 16-pin SOIC package. It operates with a supply voltage range of 4.5 V to 5.5 V and supports propagation delays of up to 45 ns. The device features LSTTL-compatible inputs and CMOS outputs, ensuring compatibility with standard digital interfaces. Designed for surface-mount applications, it functions within an industrial temperature range of -55°C to +125°C and includes power dissipation ratings of 500 mW.
Feature Summary
- Dual independent 4:1 multiplexing or demultiplexing channels
- LSTTL input levels compatible with standard TTL logic families
- CMOS output structure for low static power consumption
- Industrial temperature rating supporting wide environmental operation
Applications
- Data routing in embedded control systems
- Signal selection in communication interface circuits
- Address decoding in memory subsystems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives by checking the component marking or official documentation. Confirm that the intended application environment remains within the specified electrical and thermal limits defined in the official product data.
Selection Notes
Select this component when dual 4:1 signal switching is required with HCT logic compatibility. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 16-SOIC footprint for PCB layout constraints. Compare propagation delay characteristics against other HCT series devices if timing-critical performance is necessary for the target design.
Part Context
This part belongs to the MC74HCT4852A series of analog switches and multiplexers manufactured by onsemi. It is part of the broader 74HCT logic family, which bridges CMOS technology with TTL input requirements. The device serves as a fundamental building block for digital signal routing in mixed-signal environments requiring reliable switching capabilities.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 74HCT4852 parts. Verify pinout compatibility and electrical parameters such as on-resistance and leakage current before substitution.
