ADG438FBN Description

Short technical summary and product information.

The ADG438FBN is a CMOS analog multiplexer designed for fault protection, employing a series n-channel, p-channel, and n-channel MOSFET structure. It provides continuous overvoltage protection from -40 V to +55 V during both normal operation and power-loss conditions. With power supplies off, the multiplexer input appears as an open circuit, protecting both the device and signal source.

Key electrical characteristics include a maximum turn-on time of 250 ns and a turn-off time of 150 ns, making it suitable for high-speed signal routing. The break-before-make construction ensures no momentary shorting between channels when switching. Logic inputs are TTL and CMOS compatible, simplifying interfacing with standard digital controllers.

This multiplexer is ideal for data acquisition systems, industrial process control, avionics test equipment, and other high-reliability applications where signal integrity and fault protection are critical. The device is housed in a 16-lead PDIP package (16-DIP) with through-hole mounting, offering robust mechanical connections for prototyping and production environments.
