Overview
The MC74HC4052ADR2 is a dual analog multiplexer/demultiplexer manufactured by onsemi, utilizing silicon-gate CMOS technology. It features two independent SP4T switches with common outputs/inputs. The device operates within a digital supply range of 2.0 V to 6.0 V and an analog supply range of ±2.0 V to ±6.0 V (total span 2.0 V to 12.0 V). Key electrical parameters include a maximum ON resistance of 190 Ω at 4.5 V and 100 Ω at 6.0 V, propagation delays up to 245 ns, and off-channel leakage current of 1.0 μA. It is housed in a 16-SOIC package.
Feature Summary
- Dual independent SP4T analog switching architecture
- Silicon-gate CMOS construction for low noise and linearity
- Diode protection integrated on all inputs and outputs
Applications
- Analog signal routing in data acquisition systems
- Multiplexing multiple sensor inputs to a single ADC
- Audio signal path switching
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. Ensure the component meets RoHS compliance requirements if applicable to the design. Cross-reference the full part number with the latest datasheet revision history to confirm availability status and any potential manufacturing site changes.
Selection Notes
Select this component when dual independent 4-to-1 analog switching is required within standard CMOS logic levels. Verify that the analog signal voltage swing remains within the specified VCC to VEE range to prevent excessive current draw. Consider the maximum ON resistance and propagation delay specifications relative to the target signal frequency and bandwidth requirements.
Part Context
This device belongs to the MC74HC405xA family of high-performance analog multiplexers. It shares pinout compatibility with older metal-gate counterparts like the MC14052B. The HC4052 variant specifically provides two independent channels, distinguishing it from the single-channel HC4051 and triple-channel HC4053 models within the same series.

FAQ
How does the analog power supply range differ from the digital control supply?
The analog power supply (VCC - VEE) supports a total span of 2.0 V to 12.0 V, allowing analog signals to vary across this entire range. The digital control supply (VCC - GND) is limited to 2.0 V to 6.0 V.
What is the function of the Enable pin?
When the Enable pin is set to HIGH, all analog switches within the device are turned off, placing the outputs in a high-impedance state regardless of the Channel-Select inputs.
Is the ON resistance linear over the input voltage range?
Yes, the device is designed so that the ON resistance (Ron) exhibits improved linearity over the input voltage compared to metal-gate CMOS analog switches.
