MC74LVXT4052DTR2

Overview

The MC74LVXT4052DTR2 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features double-pole, 4-position plus common-off architecture within a TSSOP-16 package. The device operates with a digital supply voltage (VCC) ranging from 2.5 V to 6.0 V and an analog supply range (VCC - VEE) of ±3.0 V to ±3.0 V. Key electrical parameters include a maximum ON resistance of 86 Ω at 3.0 V, propagation delays up to 40 ns, and a bandwidth of 80 MHz. It supports single or split supplies, offers low crosstalk, and includes break-before-make circuitry.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low leakage currents.
• Features channel-select inputs compatible with standard TTL logic levels.
• Provides improved linearity and lower ON resistance compared to metal-gate counterparts.
• Incorporates break-before-make circuitry to prevent signal shorting during switching.

Applications

• Signal routing in data acquisition systems
• Audio and video signal switching applications
• Programmable gain amplifier input selection
• Battery-powered portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix 'DTR2' corresponds to the TSSOP-16 tape and reel packaging configuration containing 2500 units per reel. Confirm RoHS compliance status if required for environmental regulations, as lead-free variants are available under different suffixes such as DR2G. Ensure the component matches the intended moisture sensitivity level requirements for surface mount assembly processes.

Selection Notes

Select this component when a dual 4-to-1 analog switch is required with TTL-compatible control logic. It is suitable for applications needing operation across a wide voltage range from 2.5 V to 6.0 V. Consider the TSSOP-16 package for space-constrained designs. Verify that the analog signal swing remains within the VCC to VEE limits to ensure proper functionality and avoid damage.

Part Context

This part belongs to the LVXT series of analog switches from onsemi, designed for high-speed performance. It shares pinout compatibility with HC4052A and MC14052B devices, facilitating direct upgrades in existing designs. The LVXT family emphasizes low ON resistance and improved linearity over previous metal-gate technologies, making it ideal for precision analog signal handling.

Replacement Considerations

Direct pin-compatible replacements include the MC74LVXT4052DR2G (SOIC-16, Tape & Reel) and MC74LVXT4052DG (SOIC-16, Tube). For alternative packages, the MC74LVXT4052DT (TSSOP-16, Tube) serves as a non-reel option. Cross-reference with HC4052A or MC14052B only if voltage and speed specifications align with system requirements.

FAQ

Can the MC74LVXT4052 operate with a single supply?

Yes, the device is designed to operate on a single supply where VEE is connected to GND, provided VCC is between 2.5 V and 6.0 V.

What is the maximum analog input voltage allowed?

The analog input voltage can vary across the complete power supply range, from VEE to VCC, without damaging the device.

How does the device handle unused channels?

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