Overview
The SC74HC4852ADTR2G is a dual four-channel analog multiplexer/demultiplexer manufactured by onsemi using silicon gate CMOS technology. It features injection current effect control, allowing signals at disabled inputs to exceed the supply voltage range without affecting the enabled channel. The device operates within a wide supply voltage range of 2V to 6V and supports surface-mount installation in a 16-TSSOP package. Key electrical parameters include a maximum on-resistance of 400 ohms, an off-state leakage current of 100nA, and a channel capacitance of 40pF. It functions as an SP4T switch circuit with two independent channels.
Feature Summary
- Injection current effect control for signal integrity during over-voltage conditions
- Dual configuration providing two independent 4-to-1 analog switching paths
- Wide operating supply voltage range suitable for various logic levels
Applications
- Automotive applications requiring protection against voltage spikes
- Signal routing in data acquisition systems
- Audio and video signal switching circuits
Procurement Notes
Verify the specific suffix 'DTR' against the manufacturer's official documentation to confirm the tape and reel packaging quantity and orientation. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design. Cross-reference the RoHS status and material declaration with the latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when dual 4-to-1 analog switching is required with high noise immunity. The injection current protection feature makes it suitable for environments where input signals may exceed the supply rails. Compare the 400-ohm on-resistance and 100nA leakage current against system requirements to ensure signal fidelity is maintained across the operating temperature range.
Part Context
This part belongs to the MC74HC4852A series of analog multiplexers. It is functionally compatible with other industry-standard 4852 devices but offers specific manufacturing characteristics from onsemi. The device is designed to replace external diode-resistor networks typically used for protection, simplifying the circuit design.
Replacement Considerations
The MC74HC4852ADR2G (SOIC package) is a verified alternative offering identical electrical performance in a different footprint. Verify pin compatibility and thermal dissipation requirements when substituting between TSSOP and SOIC packages.
