MC74LVXT4066DTR2

Overview

The MC74LVXT4066DTR2 is a discontinued quad analog switch manufactured by onsemi. It utilizes silicon-gate CMOS technology to provide fast propagation delays and low ON resistance. The device features four independent bilateral switches capable of controlling analog and digital voltages across the full power-supply range from VCC to GND. It operates within a supply voltage range of 2.0 V to 5.5 V, with an operating temperature range of -55°C to +85°C. Key electrical parameters include a maximum ON resistance of 30 Ω at 5.5 V, a bandwidth of 160 MHz at 5.5 V, and a propagation delay of 2.0 ns at 5.5 V.

Feature Summary

Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate CMOS devices.
Features diode protection on all inputs and outputs, allowing overvoltage tolerance up to 7.0 V regardless of supply voltage.
Provides high ON/OFF output voltage ratio and low crosstalk between switches.

Applications

Low voltage logic level shifting between different CMOS logic families.
4-input multiplexer configurations.
Sample/hold amplifier circuits.

Procurement Notes

This component has been officially discontinued by onsemi as of July 22, 2026. It is not recommended for new designs. Verification of current availability should be conducted through authorized distributors or by contacting onsemi representatives directly for potential surplus stock or alternative recommendations.

Selection Notes

Designers should consider that this part is obsolete and no longer in production. When selecting a replacement, verify compatibility with existing pinouts and electrical specifications, particularly the supply voltage range and package type. Ensure any substitute component meets the required signal integrity and switching speed characteristics for the specific application.

Part Context

The MC74LVXT4066 belongs to the LVXT series of high-performance analog switches. It shares pinout compatibility with the older metal-gate CMOS MC14066 and the high-speed HC4066A. The D suffix indicates the SOIC-14 NB package, while the TR2G suffix denotes tape and reel packaging with lead-free composition.
