Overview
The MC74LVX4066MEL is a quad analog switch manufactured by onsemi, utilizing high-performance silicon-gate CMOS technology. It features four independent bilateral switches capable of controlling analog and digital voltages across the full power-supply range from VCC to GND. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range of -55°C to +85°C. Key electrical characteristics include a maximum ON resistance of 40 Ω at 3.0 V and 25 Ω at 5.5 V (at 25°C), with propagation delays ranging from 1.0 ns to 6.0 ns depending on voltage. The component is housed in a TSSOP-14 package.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low ON resistances.
- Provides improved linearity and lower ON resistance over input voltage compared to metal-gate CMOS equivalents.
- Includes diode protection on all inputs and outputs to guard against static discharge.
- Features low crosstalk between switches and low OFF-channel leakage current.
Applications
- Multiplexer and demultiplexer signal routing
- Sample-and-hold amplifier circuits
- TTL/NMOS-to-CMOS level conversion interfaces
Procurement Notes
Verify the specific ordering suffix 'MEL' against official documentation, as standard listings often utilize 'D' or 'DR2G'. Confirm availability status directly with the manufacturer or authorized distributors, as component lifecycle stages may affect procurement options.
Selection Notes
Select this component when designing circuits requiring low ON resistance and high linearity for analog signal switching within a 2.0 V to 6.0 V supply range. Ensure the application does not exceed the maximum voltage differential of 1.2 V across the switch while ON to prevent excessive current draw.
Part Context
This device belongs to the LVX logic family, designed for low-voltage applications. It serves as a functional equivalent to the HC4066A and MC14066 in terms of pinout, offering enhanced performance metrics such as faster propagation delays and better resistance linearity for modern mixed-signal designs.

FAQ
What is the maximum voltage differential allowed across the switch when it is ON?
The maximum static or dynamic voltage across the switch (VIO) is 1.2 V. Exceeding this limit may cause excessive VCC current draw.
How does the ON resistance vary with supply voltage?
The ON resistance increases as the supply voltage decreases. For example, at 3.0 V, the maximum Ron is 40 Ω, whereas at 5.5 V, it drops to 25 Ω at 25°C.
Is the device compatible with LSTTL outputs?
Yes, the ON/OFF control inputs are compatible with standard CMOS outputs and can interface with LSTTL outputs when pull-up resistors are used.
