MC74HC4052AD

Overview

The MC74HC4052AD is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features a double-pole, 4-position configuration with a common off state, utilizing two independent switches controlled by shared channel-select inputs (A and B) and a single enable pin. 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 a propagation delay of up to 320 ns at VCC = 2.0 V. It operates within a temperature range of -55°C to +125°C and is housed in a SOIC-16 package.

Feature Summary

• Dual-channel architecture allowing simultaneous switching of two independent 4-to-1 paths via shared select logic.
• Enhanced linearity and lower ON resistance compared to metal-gate CMOS counterparts due to silicon-gate technology.
• Integrated diode protection on all inputs and outputs to guard against static discharge and voltage transients.
• Low crosstalk and low noise characteristics suitable for precision analog signal routing applications.

Applications

• Analog signal routing in data acquisition systems
• Audio and video signal switching circuits
• Programmable gain amplifier input selection
• Multiplexing sensor arrays for monitoring

Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping quantity. The 'D' suffix indicates a standard SOIC-16 package. Confirm RoHS compliance status as older revisions may differ from current manufacturing standards. Check for lead-free markings if environmental regulations apply to your assembly process.

Selection Notes

Select this component when dual independent analog channels are required within a single package. Ensure the analog signal swing remains within the VCC to VEE limits. Verify that the control logic levels match the VCC supply voltage. Consider the ON resistance variation across the input voltage range for signal integrity requirements.

Part Context

This device belongs to the HC405xA family of analog switches, which also includes the 8-channel MC74HC4051A and the triple 2-channel MC74HC4053A. All members share identical pinouts and similar performance characteristics, facilitating design flexibility and board space optimization in multi-switch applications.

Replacement Considerations

Compatible replacements include other 74HC4052 variants from different manufacturers such as NXP or Texas Instruments, provided they meet the same SOIC-16 footprint and electrical specifications. Verify pin compatibility and ensure the substitute supports the required analog voltage range.

FAQ

What is the function of the Enable pin?

When the Enable pin is HIGH, all analog switches are turned off, placing the outputs in a high-impedance state regardless of the Channel-Select inputs. When LOW, the selected channels are connected.

Can the device operate with a single supply?

Yes, the device can operate with a single supply by connecting VEE to GND. In this configuration, the analog signals must remain between GND and VCC.

How does the ON resistance vary?

The ON resistance (Ron) varies with the input voltage and supply voltage. It is more linear over the input voltage range than metal-gate CMOS switches, but still exhibits some variation depending on the VIS level relative to VEE.
