MC74LVX4052DTR2

Overview

The MC74LVX4052DTR2 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features double-pole, 4-position plus common-off configuration with independent control of each switch via Channel-Select inputs A and B. The device operates within a digital power supply range (VCC to GND) of 2.5 V to 6.0 V and supports an analog power supply range (VCC to VEE) from -3.0 V to +3.0 V. Key electrical parameters include a maximum ON resistance of 86 Ω at 3.0 V, propagation delays up to 40 ns, and a bandwidth of 80 MHz. It utilizes break-before-make circuitry and offers low crosstalk and leakage currents.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low ON resistance.
• Features improved linearity and lower ON resistance compared to metal-gate or HSL counterparts.
• Incorporates break-before-make circuitry to prevent signal shorting during channel switching.
• Supports operation on single supplies (VEE = GND) or split supplies up to ±3.0 V.

Applications

• Signal routing in data acquisition systems
• Audio and video signal switching
• Programmable gain amplifiers
• Isolation of analog signals in mixed-signal circuits

Procurement Notes

Verify the ordering suffix 'R2' corresponds to the tape and reel packaging format specified in the manufacturer's documentation. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure the SOIC-16 package dimensions align with the PCB footprint design guidelines provided in the datasheet.

Selection Notes

Select this component when low ON resistance and high linearity are critical for analog signal integrity. The LVX series is suitable for applications requiring compatibility with standard CMOS logic levels. Consider the operating temperature range of -55°C to +125°C for industrial environments. Verify that the supply voltage constraints fit within the 2.5 V to 6.0 V digital and ±3.0 V analog limits.

Part Context

The MC74LVX4052 belongs to the LVX family of high-speed CMOS logic devices. It is functionally similar to the HC4052A and MC14052B but offers improved performance characteristics such as lower ON resistance and better linearity. The device is designed for applications requiring reliable analog switching with minimal signal distortion across a wide voltage range.

Replacement Considerations

Direct replacements include MC74LVX4052DR2G and MC74LVX4052DG. Alternative packages such as TSSOP-16 (MC74LVX4052DT) or SOEIAJ-16 (MC74LVX4052M) may be considered if pinout compatibility is maintained. Verify that any substitute maintains the same electrical specifications and package dimensions.

FAQ

How does the MC74LVX4052 handle unused analog channels?

Unused analog inputs/outputs may be left floating. However, tying them to VCC or GND through a low-value resistor helps minimize crosstalk and feedthrough noise.

What is the purpose of the Enable pin?

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

Can the device operate with split supplies?

Yes, the device is designed to operate with split supplies up to ±3.0 V, allowing it to control analog voltages ranging from VEE to VCC.
