MC74LVX4053DR2

Overview

The MC74LVX4053DR2 is a triple single-pole double-throw (SPDT) analog multiplexer/demultiplexer manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology to achieve fast propagation delays, low ON resistance, and low OFF leakage currents. The device supports an analog power supply range of -3.0 V to +3.0 V and a digital control supply range of 2.5 V to 6.0 V. It features three independent switches with channel-select inputs A, B, and C, and a common Enable pin. When the Enable input is HIGH, all analog switches are turned off. The package type is SOIC-16.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low noise performance.
• Features improved linearity and lower ON resistance compared to metal-gate or High-Speed CMOS counterparts.
• Incorporates break-before-make circuitry to prevent signal overlap during switching transitions.
• Supports operation on a single supply (VEE = GND) or split supplies up to +/-3.0 V.

Applications

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

Procurement Notes

Verify the specific ordering suffix DR2 corresponds to the SOIC-16 tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the manufacturer's current product specifications. Ensure the component matches the required lead-free package standards for your assembly process.

Selection Notes

Select this component when low ON resistance and high bandwidth are required for analog signal paths. Verify that the digital control voltage levels are compatible with your system logic family. Consider the thermal dissipation capabilities of the SOIC-16 package if operating at elevated temperatures or high load currents.

Part Context

This part belongs to the MC74LVX4053 series of analog multiplexers. It shares pinout compatibility with devices such as the LVX8053, HC4053A, and metal-gate MC14053B. The series is designed for applications requiring high-speed analog switching with low distortion and crosstalk characteristics.

Replacement Considerations

Direct functional substitutes include the MC74LVX4053D (tube packaging) or MC74LVX4053DG (Pb-free tube). Cross-manufacturer equivalents like the SN74LV4053ATPWREP may be considered but require verification of electrical parameters and pinout compatibility.

FAQ

What is the maximum analog voltage swing supported by the device?

The analog voltage can vary across the complete power supply range from VCC to VEE. For example, with VCC at +5V and VEE at GND, the signal can swing between these limits.

How does the Enable pin affect the switch state?

When the Enable pin is set to a HIGH logic level, all three analog switches within the device are turned off, isolating the common outputs/inputs from the selected channels.

Is the device compatible with LSTTL outputs?

Yes, with the addition of pullup resistors, the Channel-Select and Enable inputs are compatible with LSTTL output logic levels.
