PRODUCT HIGHLIGHTS The ADG438F/ADG439F are CMOS analog multiplexers, the ADG438F comprising 8 single channels and These multiplexers provide fault protection. Using a series n-channel, p-channel, nchannel MOSFET structure, both device and signal source protection is provided in the event of an overvoltage or power loss. During fault conditions, the multiplexer input (or output) appears as an open circuit and only a few nanoamperes of leakage current will flow.
