MC74LVX4052D

Overview

The MC74LVX4052D is a dual 4-channel analog multiplexer/demultiplexer manufactured by onsemi using silicon-gate CMOS technology. It operates with a digital supply voltage (VCC) ranging from 2.5 V to 6.0 V and an analog supply range (VCC - VEE) of ±3.0 V. The device features a maximum ON resistance of 86 Ω at 3.0 V, propagation delays up to 40 ns, and a bandwidth of 80 MHz. Packaged in a SOIC-16 case 751B-05, it supports single or split supplies, includes break-before-make circuitry, and offers low crosstalk and leakage currents.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low power consumption.
• Provides improved linearity and lower ON resistance compared to metal-gate or HSL counterparts.
• Incorporates break-before-make circuitry to prevent signal shorting during channel transitions.
• Supports independent control of two separate 4-to-1 switches via dedicated channel-select inputs.

Applications

• Signal routing in data acquisition systems requiring analog voltage selection.
• Audio signal processing circuits utilizing low noise and high isolation characteristics.
• Test and measurement equipment needing precise analog switch control within wide supply ranges.

Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-16 package configuration as defined in the official datasheet. Confirm RoHS compliance status if required, noting that Pb-free variants carry the 'G' suffix. Ensure environmental specifications match the intended operating temperature range of -55°C to +125°C for reliable performance.

Selection Notes

Select this component when designing circuits requiring dual independent analog switches with low ON resistance and high linearity. It is suitable for applications demanding operation across a wide voltage range from 2.5 V to 6.0 V. Consider the SOIC-16 package constraints and thermal dissipation requirements relative to the 500 mW power rating in still air.

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 picked up by the unused switch.

What is the recommended protection for voltage transients?

When voltage transients above VCC or below VEE are anticipated, external Germanium or Schottky diodes are recommended to absorb maximum anticipated current surges during clipping.

Can the device operate with a single supply?

Yes, the device is designed to operate on a single supply where VEE is connected to GND, or using split supplies up to ±3.0 V.
