MC74LVXT4053MEL

Overview

The MC74LVXT4053MEL 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 and low ON resistance. The device operates with a digital power supply range of 2.5 V to 6.0 V and an analog power supply range from -3.0 V to +3.0 V relative to ground. Key electrical parameters include a maximum ON resistance of 86 Ohms at 3.0 V, a typical propagation delay of 28 ns at 3.0 V, and a bandwidth of 80 MHz. It features break-before-make circuitry and TTL-compatible channel-select inputs.

Feature Summary

• Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate or High-Speed CMOS counterparts.
• Features independent control of three SPDT switches with break-before-make circuitry to prevent signal shorting during switching.
• Supports both single-supply operation (VEE = GND) and split supplies up to ±3.0 V for wide analog voltage handling.

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 'MEL' corresponds to the SOEIAJ-16 package in tape and reel format containing 2000 units per reel. Confirm RoHS compliance status if required, as standard versions may differ from Pb-Free designations. Ensure the component matches the exact datasheet revision referenced for your design requirements.

Selection Notes

Select this component when requiring low ON resistance and high linearity within a 2.5 V to 6.0 V digital logic environment. It is suitable for designs needing TTL-compatible control signals and independent switch control. Consider the SOEIAJ-16 package constraints and thermal dissipation limits of 500 mW in still air when designing the PCB layout.

Part Context

This part belongs to the LVXT series of analog multiplexers from onsemi. It shares pinout compatibility with the LVX8053, HC4053A, and MC14053B families. The device is designed to handle analog voltages varying across the complete power supply range, making it versatile for mixed-signal applications requiring precise signal path management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical specifications against alternative vendors if cross-referencing with HC4053A or LVX8053 equivalents.

FAQ

What is the maximum analog voltage swing supported?

The maximum analog voltage swing is determined by the supply voltages VCC and VEE. The positive peak should not exceed VCC, and the negative peak should not go below VEE.

How does the device handle unused analog inputs/outputs?

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

What protection is recommended for voltage transients?

External Germanium or Schottky diodes are recommended to absorb current surges during clipping if voltage transients above VCC or below VEE are anticipated on the analog channels.
