MC74LVXT4052MELG

Overview

The MC74LVXT4052 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer featuring double-pole, four-position switching with common off capability. It operates on a digital supply (VCC) of 2.5 V to 6.0 V and an analog supply range (VCC - VEE) from -3.0 V to +3.0 V. The device ensures low ON resistance linearity and fast propagation speeds, with typical delays of 28 ns at 3.0 V. Control inputs are TTL-compatible, and it supports break-before-make circuitry to prevent shorting during channel transitions.

Feature Summary

• Silicon-gate CMOS technology provides improved ON resistance linearity compared to metal-gate counterparts
• Break-before-make circuitry prevents signal shorting during channel switching
• Channel-select and enable inputs are compatible with standard TTL logic levels
• Supports single-supply operation or split supplies up to +/- 3.0 V

Applications

• Analog signal routing in data acquisition systems
• Audio and video signal switching applications
• Test and measurement equipment requiring low crosstalk
• Battery-powered devices utilizing single-supply configurations

Procurement Notes

Verify the specific ordering suffix matches the required package type, such as M for SOEIAJ-16 or D for SOIC-16. Confirm Pb-Free status if environmental compliance is mandatory, indicated by the G suffix. Ensure tape and reel quantities align with production needs, noting that the MEL suffix corresponds to 2000 units per reel. Cross-reference the datasheet revision to confirm pinout consistency.

Selection Notes

Select this component when linear analog switching is critical, as its silicon-gate construction offers superior RON linearity over metal-gate alternatives. Choose based on the required analog voltage swing; ensure VCC and VEE settings accommodate the full signal range. Verify that control logic voltages match the TTL-compatible input thresholds defined in the DC characteristics table for reliable interfacing.

Part Context

This device belongs to the LVXT family of high-speed CMOS logic components designed for low-voltage applications. It serves as a direct pin-compatible replacement for older HC4052A and MC14052B devices while offering faster switching speeds and lower power consumption. The family emphasizes performance in portable and battery-operated electronic systems requiring efficient analog signal management.

Replacement Considerations

Public confirmed substitutes include MC74LVXT4052D and MC74LVXT4052DT for different packaging options within the same manufacturer lineup. No cross-manufacturer equivalents are verified in the provided documentation.
