Overview
The MC74HC4052ADTG is a discontinued dual analog multiplexer/demultiplexer manufactured by onsemi in a TSSOP-16 package. It features two independent SP4T switches with common outputs, controlled by digital select inputs A and B. The device operates on a single supply voltage (VCC) of 2.0 V to 6.0 V or a dual supply configuration where the total span (VCC - VEE) ranges from 2.0 V to 12.0 V. Key electrical specifications include a maximum ON resistance of 190 Ω at VCC = 4.5 V and VEE = 0 V, with a channel-to-channel matching of 30 Ω. Propagation delays are guaranteed up to 350 ns at VCC = 2.0 V. The component supports an operating temperature range of -55°C to +125°C.
Feature Summary
- Dual independent SP4T analog switching architecture
- Silicon-gate CMOS technology for low leakage and improved linearity
- Diode protection integrated on all input and output pins
Applications
- Analog signal routing in data acquisition systems
- Signal conditioning circuits requiring multiplexing
- Audio and video signal path selection
Procurement Notes
This part number is officially marked as discontinued in the datasheet revision history dated July 15, 2026. Verification of current availability requires direct consultation with the manufacturer or authorized distributors, as standard inventory channels may no longer stock this specific suffix variant.
Selection Notes
Designers should verify that the required analog voltage swing remains within the VCC to VEE limits. Ensure control logic levels are compatible with the HC series CMOS inputs. For applications requiring higher speed or lower on-resistance, review alternative devices within the MC74HC405x family or newer generations.
Part Context
The MC74HC4052ADTG belongs to the MC74HC405xA series, which includes the MC74HC4051A (8:1) and MC74HC4053A (2:1). These devices share pinout compatibility with older metal-gate MC1405xAB counterparts but offer improved performance characteristics due to silicon-gate CMOS processing.

FAQ
What is the function of the Enable pin?
When the Enable pin is held HIGH, all analog switches within the device are turned off, isolating the common outputs from the selected channels.
How does the device handle analog signals exceeding the digital supply?
The analog inputs/outputs can handle voltages ranging from VEE to VCC, allowing operation with dual supplies where the total span reaches up to 12.0 V, even if the digital control supply is only 6.0 V.
Is the ON resistance constant across the signal range?
The ON resistance varies with the input voltage, but the silicon-gate CMOS technology ensures it is more linear over the input voltage range compared to older metal-gate CMOS switches.
