CD74HC4066ME4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4066ME4 is a high-speed CMOS logic quad bilateral switch manufactured by Texas Instruments. It integrates four independent single-pole single-throw (SPST) analog switches within a single 14-pin SOIC package. The device operates on a single supply voltage ranging from 2 V to 10 V, ensuring compatibility with standard logic families. Key electrical specifications include a maximum on-resistance of 70 ohms and a bandwidth of 200 MHz. Propagation delays are characterized by a maximum turn-on time of 12 ns and a maximum turn-off time of 24 ns at typical operating conditions. The component supports an extended industrial temperature range from -55°C to +125°C.
