The MAX4639EUE+T is an Analog Devices low-voltage analog multiplexer switch IC. It is available in both single 8:1 and dual 4:1 versions and features a 3.5 ohm on-state resistance (Ron). This device can handle analog signals from 0V to Vcc with a low distortion and fast settling time, making it suitable for use in audio routing applications. Its low supply current and low Ron make it suitable for low-power, energy-saving designs. This device features a logic supply voltage range of 2.3V to 5.5V, making it suitable for many microcontroller-driven and power-efficient applications.The device also includes an on-chip TTL/CMOS-compatible logic control, allowing it to be used to switch between up to 8 signals in the single 8:1 version or up to 4 signals in the dual 4:1 version. The device features low logic power consumption and is protected against overvoltage, latch-up, and ESD for reliable operation. In addition, the MAX4639EUE+T is housed in a space-saving SOIC-8 package, suitable for cost-sensitive applications such as consumer electronics.
