MC74LVXT4066DTRG

Overview

The MC74LVXT4066DTRG is a discontinued quad analog switch manufactured by onsemi, housed in a TSSOP-14 package. It operates on a single supply voltage ranging from 2.0 V to 5.5 V and supports an analog input voltage range of 2.0 V to 6.0 V. The device features four independent bilateral switches with a maximum ON resistance of 30 Ohms at 5.5 V and 25°C. Propagation delays are specified at 8.0 ns for analog-to-analog switching and 40 ns for control-to-output transitions at 5.5 V. The component provides high bandwidth (160 MHz), low crosstalk (-80 dB), and includes diode protection on all inputs and outputs.

Feature Summary

Four independent bilateral analog switches designed for signal routing
Diode protection on all inputs and outputs for overvoltage tolerance
Logic-level translation capability between different CMOS logic families
Low noise and improved linearity compared to metal-gate CMOS switches

Applications

Low voltage logic level shifting between 1.8 V and 3.0 V systems
Multiplexer and demultiplexer configurations for data routing
Sample-and-hold amplifier circuits
Interfacing 5.0 V circuits to 3.0 V circuits

Procurement Notes

This specific part number is officially discontinued and not recommended for new designs. Verification of current availability requires direct contact with the manufacturer or authorized distributors. Alternative sourcing should focus on replacement components listed in official documentation rather than attempting to procure this obsolete item.

Selection Notes

Designers should evaluate the MC74LVXT4066DR2G as a potential alternative, which utilizes a SOIC-14 NB package instead of the TSSOP-14 form factor. Both devices share identical electrical characteristics and pinouts. Selection must account for the discontinuation status and ensure that any substitute meets the required operating temperature range and power dissipation limits.

Part Context

The MC74LVXT4066 belongs to the LVXT series of high-performance silicon-gate CMOS analog switches. It is electrically compatible with the MC14066 and HC4066A but offers superior linearity and lower ON resistance. The device is designed to handle analog signals varying across the full power-supply range while maintaining compatibility with standard LSTTL and CMOS logic levels.
