MC74HC4052ADWG

Overview

The MC74HC4052ADWG is a dual analog multiplexer/demultiplexer manufactured by onsemi using silicon-gate CMOS technology. It features two independent SP4T switches with common outputs/inputs, controlled by shared channel-select inputs A and B. 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. Key electrical parameters include a maximum ON resistance of 190 Ω at VCC=4.5 V and 280 Ω at VCC=6.0 V (-55°C to 25°C). Propagation delays are typically 75 ns max at VCC=6.0 V. It operates within a temperature range of -55°C to +125°C and is housed in a SOIC-16 Wide package.

Feature Summary

• Dual-channel architecture providing two independent SP4T analog switches
• Silicon-gate CMOS construction for improved linearity and lower ON resistance compared to metal-gate counterparts
• Diode protection integrated on all inputs and outputs
• Compatible with standard CMOS logic levels and LSTTL outputs when pull-up resistors are used

Applications

• Analog signal routing and switching in data acquisition systems
• Multiplexing multiple sensor inputs to a single ADC channel
• Audio signal path selection and mixing applications
• Test and measurement equipment requiring low crosstalk isolation

Procurement Notes

Verify the specific suffix 'DWG' corresponds to the SOIC-16 Wide package and Pb-Free status as defined in the manufacturer's ordering information. Confirm that the assembly location and wafer lot codes match project requirements. Ensure compliance with RoHS directives and check for any automotive qualification prefixes if required for the target application environment.

Selection Notes

Select this component when dual independent 4-to-1 analog switching is required within a single package. Compare ON resistance linearity and leakage current specifications against alternative HC4052 variants. Consider the wide operating voltage range and high input impedance characteristics suitable for precision analog circuits. Verify thermal dissipation capabilities for the intended PCB layout and ambient temperature conditions.

Part Context

This part belongs to the MC74HC405xA family of high-performance silicon-gate CMOS analog multiplexers. It shares pinout compatibility with older metal-gate devices like the MC14052B but offers superior performance metrics including faster propagation speeds and lower noise. The family includes related parts such as the HC4051A (8:1) and HC4053A (3:2) for different channel configurations.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' HC4052 derivatives. Verify equivalent ON resistance, leakage current, and supply voltage ranges before substitution. Check for differences in package dimensions if transitioning between standard and wide SOIC formats.
