Rochester Electronics Interface - Analog Switches, Multiplexers, Demultiplexers ADG439FBRZ

The ADG439FBRZ is a CMOS analog multiplexer featuring four differential channels, designed for high-performance applications. It provides fault protection, capable of withstanding continuous overvoltage inputs from -40 V to +55 V. In the event of power loss, all channels turn off, resulting in minimal leakage current, which protects both the multiplexer and connected circuitry. The device supports fast switching times, with a maximum turn-on time of 250 ns and turn-off time of 150 ns. It utilizes a break-before-make switching architecture, ensuring that input signals are safeguarded against momentary shorting. The ADG439FBRZ is compatible with TTL and CMOS logic levels, making it suitable for various applications, including data acquisition systems, industrial control, and avionics test equipment. With a low on-resistance of 270 Oc typical and improved off isolation due to trench isolation technology, this multiplexer is designed for reliability and efficiency in demanding environments. The operating temperature range is from -40¬8C to +125¬8C, making it versatile for a wide range of applications.
