The MC74VHC4052DR2 is a dual 4-channel analog multiplexer/demultiplexer manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology to achieve fast propagation delays, low ON resistance, and low OFF leakage currents. The device supports an analog power supply range (VCC – VEE) of 2.0 to 12.0 V and a digital control supply range (VCC – GND) of 2.0 to 6.0 V. It features diode protection on all inputs/outputs and improved linearity compared to metal-gate counterparts. The component is housed in a 16-pin SOIC package.
Verify the specific ordering suffix DR2 corresponds to the tape and reel packaging configuration when sourcing components. Confirm that the manufacturer designation matches onsemi standards to ensure authenticity. Check for RoHS compliance status as per current manufacturing declarations. Validate the pinout compatibility with existing PCB footprints before integration into new designs.
Select this component when dual independent 4-channel switching is required within a single package. Ensure the analog voltage swing stays within the specified VCC and VEE limits to prevent damage. Consider the maximum ON resistance at the operating temperature if signal integrity is critical. Verify that the digital control signals are compatible with the chosen logic family voltage levels.
This part belongs to the MC74VHC405x series, which includes the single 8-channel VHC4051 and triple 2-channel VHC4053. All devices share similar pinouts and electrical characteristics but differ in channel count and switch configuration. The VHC4052 specifically provides two separate 4-to-1 multiplexing paths, offering flexibility for differential or parallel signal processing tasks.
MC74VHC4052DTR2G is a verified substitute part number available from onsemi.
