Overview
The MC74HC4852ADTR2G is a dual 4-to-1 analog multiplexer/demultiplexer manufactured by onsemi. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. The device features two independent SP4T switches with a maximum on-resistance of 400 ohms and a channel capacitance of 40pF. Leakage current is limited to a maximum of 100nA. It is housed in a 16-TSSOP surface-mount package.
Feature Summary
- Dual independent 4:1 analog switching capability
- Injection current effect control for signal integrity
- Wide operating voltage and temperature ranges
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs
- Test and measurement equipment signal paths
Procurement Notes
Verify the complete part number, including the trailing 'G' suffix indicating RoHS compliance, as it may differ from the base model designation. Confirm the specific tape and reel packaging requirements with the supplier prior to ordering. Ensure the component meets the required environmental standards for the intended application environment.
Selection Notes
Select this component when dual 4-channel analog switching is required within a low-pin-count surface-mount footprint. Consider the 400-ohm on-resistance limit and 40pF capacitance against the signal bandwidth and impedance requirements of the application circuit.
Part Context
This part belongs to the MC74HC4852A series of analog multiplexers. It shares functional similarities with other devices in the 74HC logic family but is specifically optimized for analog signal routing applications requiring injection current control.
Replacement Considerations
The MC74HC4852ADR2G serves as a pin-compatible alternative packaged in 16-SOIC instead of TSSOP. Verify that the physical package dimensions and thermal characteristics are acceptable for the target PCB layout.
