MC74LVXT8053DTR2

Overview

The MC74LVXT8053DTR2 is a Triple Single-Pole, Double-Position Plus Common Off analog multiplexer/demultiplexer manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology to achieve fast propagation delays and low ON resistances. The device supports an analog power supply range of 2.0 V to 6.0 V and features independent control of three switches (X, Y, Z). Key electrical parameters include a maximum ON resistance of 25 Ω at 5.5 V, a bandwidth of 120 MHz, and a propagation delay of 2.0 ns from analog input to output at 5.5 V. It operates within a temperature range of -55°C to +85°C.

Feature Summary

• Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate counterparts.
• Provides independent control of three SPDT switches with channel-select inputs compatible with TTL-type thresholds.
• Features diode protection on all inputs and outputs, allowing overvoltage tolerance up to 7.0 V regardless of supply voltage.
• Supports analog voltages varying across the complete power supply range from VCC to GND.

Applications

• Logic-level translation between 3.0 V CMOS logic and 5.0 V CMOS logic.
• Interfacing 5.0 V circuits to 3.0 V circuits.
• Translating from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at higher-voltage power supplies.

Procurement Notes

Verify the package suffix 'DTR2' corresponds to the TSSOP-16 form factor before procurement. Confirm that the specific revision level matches the design requirements, as datasheet revisions may update electrical characteristics or pin configurations. Ensure compatibility with the required operating temperature range of -55°C to +85°C for the intended application environment.

Selection Notes

Select this component when requiring triple SPDT switching with low crosstalk and high bandwidth. It is suitable for applications needing interface between different logic voltage levels due to its robust input protection. Consider the TSSOP-16 package constraints if space is limited. Verify that the analog signal swing remains within the 2.0 V to 6.0 V supply range to ensure proper operation.

Part Context

This part belongs to the MC74LVXT8053 family of analog multiplexers. It shares functional similarities with the HC4053A and MC14053B but offers enhanced performance through silicon-gate CMOS technology. The 'DTR2' suffix specifically denotes the Tape & Reel packaging in the TSSOP-16 case, distinguishing it from SOIC or SOEIAJ variants.

Replacement Considerations

Direct replacements include MC74LVXT8053DR2G (SOIC-16) and MC74LVXT8053M (SOEIAJ-16), provided the package footprint is adaptable. Other LVXT series multiplexers may serve as functional substitutes if pinout and electrical specifications align with the design requirements.

FAQ

What is the maximum voltage tolerance for the inputs?

The device provides protection circuitry that allows overvoltage tolerance on the inputs up to 7.0 V, regardless of the supply voltage.

How does the ON resistance vary with supply voltage?

The ON resistance decreases as the supply voltage increases; for example, it is guaranteed at a maximum of 25 Ω at 5.5 V and 40 Ω at 3.0 V.

Can unused analog inputs/outputs be left floating?

Yes, unused analog inputs and outputs may be left floating, though tying them to VCC or GND through a low-value resistor can help minimize crosstalk and feedthrough noise.
