Overview
The MC74HC4852ANG is a dual four-channel analog multiplexer/demultiplexer manufactured using silicon gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V and features injection current effect control, allowing signals at disabled inputs to exceed the supply voltage without affecting the enabled channel. The device provides two independent SP4T switches with a maximum on-resistance of 400 Ω and a typical propagation delay of 40 ns. It supports surface mount installation in a 16-SOIC package and functions reliably across an extended temperature range from -55 °C to +125 °C.
Feature Summary
- Injection current effect control prevents signal interference when disabled input channels exceed the supply voltage range.
- Dual configuration integrates two independent four-to-one analog switching circuits within a single package.
- High noise immunity ensures stable operation with minimum noise margins defined as a percentage of the supply voltage.
Applications
- Automotive electronic systems requiring robust signal routing under varying voltage conditions
- Industrial data acquisition systems utilizing analog signal multiplexing
- Test and measurement equipment requiring precise analog signal selection
Procurement Notes
Verify the specific suffix 'A' against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status through the supplier's material declaration. Ensure the 16-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component for applications requiring dual analog switching with high-voltage tolerance on inactive channels. Compare the 400 Ω maximum on-resistance against circuit loss requirements. Verify that the 2 V to 6 V operating range aligns with the system power supply constraints and that the SOIC-16 package fits the available board space.
Part Context
This part belongs to the MC74HC4852A series of analog multiplexers. It serves as a functional replacement for legacy 4052 and 4852 series devices while offering improved CMOS performance. The device is designed to eliminate external protection networks typically needed for overvoltage scenarios in analog signal paths.
Replacement Considerations
The M74HC4852 is a functionally compatible alternative from STMicroelectronics. Verify pinout alignment and on-resistance specifications before substitution. Check datasheet differences regarding injection current thresholds and package tolerances to ensure seamless integration into existing designs.
