MC74LVXT4066DR2G

Overview

The MC74LVXT4066DR2G is a discontinued quad analog switch manufactured by onsemi in a SOIC-14 package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an analog input voltage range from GND to VCC. The device features four independent bilateral switches with a maximum ON resistance of 20 Ohms at 5.5 V and 25°C. Propagation delays are specified between 1.0 ns and 8.0 ns depending on the supply voltage, while control-to-output delays reach up to 40 ns. The component provides low off-channel leakage current (1.0 µA max) and high bandwidth (160 MHz at 5.5 V).

Feature Summary

Utilizes silicon-gate CMOS technology for fast switching speeds and linear ON resistance.
Provides overvoltage tolerance on digital inputs, enabling logic-level translation between different voltage domains.
Includes diode protection on all inputs and outputs to withstand voltages up to 7.0 V regardless of supply voltage.

Applications

Low voltage logic level shifting between 1.8 V, 3.0 V, and 5.0 V CMOS circuits.
Multiplexing analog signals across single or dual power supplies.
Sample-and-hold amplifier configurations requiring precise signal routing.

Procurement Notes

This specific part number is officially discontinued and not recommended for new designs. Verification of availability should focus on legacy stock or authorized distributors holding remaining inventory. Engineers must consult onsemi representatives for current product status updates and alternative component recommendations before initiating procurement processes.

Selection Notes

Designers should evaluate the device's compatibility with LSTTL control inputs and its ability to handle analog signals spanning the full power-supply range. Consider the improved linearity compared to metal-gate CMOS alternatives like the MC14066. Ensure that the application does not exceed the maximum static voltage difference of 1.2 V across the switch when conducting significant current.

Part Context

The MC74LVXT4066 belongs to the LVXT family of high-performance silicon-gate CMOS devices. It shares pinout compatibility with the older metal-gate MC14066 and HC4066A families. The DR2G suffix indicates a lead-free SOIC-14 NB package supplied in tape and reel format. This component represents a transition toward lower voltage operation with enhanced speed characteristics.
