NXP Semiconductors Analog Switches, Multiplexers, Demultiplexers 74HC4066DB,112

The 74HC4066 is a quad single-pole single-throw analog switch designed for various applications requiring signal routing. Each switch has two input/output terminals and an active HIGH enable input, allowing for flexible control of signal paths. The device features low ON resistance, with typical values of 50 Ω at 4.5 V, 45 Ω at 6.0 V, and 35 Ω at 9.0 V, which enhances signal integrity in high-speed applications. It includes input clamp diodes, enabling the use of current limiting resistors for interfacing with voltages exceeding the supply voltage (V_CC). The product is specified for operation over a temperature range of -40 °C to +125 °C and offers ESD protection exceeding 2000 V for HBM and 200 V for MM. Multiple package options are available, including SO14, TSSOP14, and DHVQFN14, catering to different design requirements.
