MC74LVXT4053MELG

Overview

The MC74LVXT4053MELG is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features three independent single-pole double-throw (SPDT) switches with common off functionality, housed in a 16-SOEIAJ surface-mount package. The device 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. Key electrical parameters include a maximum ON resistance of 86 Ohms at 3.0 V, propagation delays of 40 ns at 2.5 V, and a bandwidth of 80 MHz. It offers low crosstalk (-70 dB), low charge injection (9 pC), and break-before-make circuitry.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low leakage currents.
• Features improved linearity and lower ON resistance compared to metal-gate or standard High-Speed CMOS counterparts.
• Incorporates break-before-make circuitry to prevent signal shorting during channel transitions.
• Provides independent control of each switch via dedicated Channel-Select inputs.

Applications

• Signal routing in data acquisition systems
• Audio and video signal switching applications
• Programmable gain amplifier circuits
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix 'MELG' corresponds to the SOEIAJ-16 tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the 'G' suffix. Ensure the component meets the required operating temperature range of -55°C to +125°C for the intended environment. Cross-reference the datasheet revision to ensure compatibility with current design specifications.

Selection Notes

Select this component when low ON resistance and high linearity are critical for signal integrity. It is suitable for designs requiring TTL-compatible control levels while handling analog signals across the full supply range. Consider the 80 MHz bandwidth and 40 ns propagation delay for high-speed switching requirements. Verify that the 16-SOEIAJ package fits the available PCB footprint constraints.

FAQ

What is the function of the Enable pin?

When the Enable pin is HIGH, all analog switches are turned off, placing the outputs in a high-impedance state.

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 is the maximum analog input voltage range?

The analog input voltage can vary across the complete power supply range, from VEE to VCC.
