MC74LVX4052M

Overview

The MC74LVX4052 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer featuring dual 4-channel configurations. It operates on a digital supply voltage (VCC) ranging from 2.5 V to 6.0 V and supports an analog power supply range (VCC - VEE) of ±3.0 V to ±3.0 V. The device provides fast propagation delays, with maximum values of 40 ns at 2.5 V and 23 ns at 4.5 V. Maximum ON resistance is specified at 86 Ω for a 3.0 V supply. It includes break-before-make circuitry, low crosstalk, and low OFF leakage currents. The component is available in SOIC-16, TSSOP-16, and SOEIAJ-16 packages.

Feature Summary

• Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate counterparts.
• Features break-before-make switching circuitry to prevent signal shorting during channel transitions.
• Supports independent control of X-switch and Y-switch channels via dedicated select inputs.
• Compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are applied.

Applications

• Signal routing in data acquisition systems
• Audio and video signal switching applications
• Programmable gain amplifier input selection

Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping configuration. Suffixes such as D indicate SOIC-16 tube packaging, while DR2G denotes SOIC-16 tape and reel. Ensure the selected variant matches the required mechanical footprint and manufacturing process specifications for the target assembly line.

Selection Notes

Select this component when dual independent 4-to-1 analog switching is required within a single package. Verify that the application's analog signal swing remains within the VCC to VEE limits. Consider the propagation delay requirements, as performance varies significantly between 2.5 V and 6.0 V supply voltages.

Part Context

This device belongs to the LVX series of analog switches, designed for low-voltage digital control of analog signals. It serves as a functional replacement for older HC4052A and metal-gate MC14052B devices, offering superior electrical characteristics and compatibility with modern low-voltage logic families.

FAQ

How does the Enable pin affect the switch state?

When the Enable pin is held HIGH, all analog switches within the device are turned off, placing the outputs in a high-impedance state regardless of the Channel Select inputs.

What is the maximum analog input voltage range?

The analog input voltage can vary across the complete power supply range, from VEE to VCC, allowing control of signals that span the entire differential supply voltage.

Is the ON resistance linear over the input voltage?

Yes, the device is designed so that the ON resistance (RON) is more linear over the input voltage range compared to traditional metal-gate CMOS or High-Speed CMOS analog switches.
