MC74LVX4052DT

Overview

The MC74LVX4052DT is a dual 4-to-1 analog multiplexer/demultiplexer manufactured by onsemi using high-performance silicon-gate CMOS technology. It operates within a digital supply voltage range of 2.5 V to 6.0 V and supports an analog power supply range from -3.0 V to +3.0 V relative to ground. The device features a maximum ON resistance of 86 Ohms at 3.0 V, with propagation delays typically ranging from 23 ns to 40 ns depending on the supply voltage. It provides a bandwidth of 80 MHz and includes break-before-make circuitry to prevent signal shorting during switching.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low leakage currents
• Supports independent control of two separate 4-position switches via dedicated channel-select inputs
• Features improved linearity and lower ON resistance compared to metal-gate or standard High-Speed CMOS counterparts
• Includes break-before-make logic to ensure safe switching without momentary shorts between channels

Applications

• Signal routing in data acquisition systems requiring analog voltage selection
• Audio signal processing circuits utilizing split power supplies
• Test and measurement equipment needing low crosstalk multiplexing
• Communication systems managing multiple analog input channels

Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-16 package configuration as listed in official documentation. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure that the datasheet revision matches the technical parameters required for your design specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require dual independent analog switching within a single package. It is suitable for applications demanding operation across both single-supply (VEE = GND) and split-supply configurations. Consider its ON resistance characteristics and propagation delay limits to ensure compatibility with the speed and impedance requirements of the connected analog signals.

Part Context

This device belongs to the MC74LVX4052 series of analog multiplexers produced by onsemi. It shares pinout compatibility with legacy devices such as the HC4052A and MC14052B, facilitating direct replacements in existing designs. The LVX series is characterized by its ability to handle analog signals varying across the complete power supply range while maintaining low distortion and noise performance.

Replacement Considerations

The MC74LVX4052DR2G serves as a tape-and-reel alternative offering identical electrical functionality but packaged in SOIC-16 format instead of TSSOP-16.
