General Description

Aeroflex’s ACT8500 is a radiation hardened, multi-chip 64 channel multiplexer MCM (multi-chip module) with ESD protection for use in space applications. It is designed to provide a high input impedance to the analog source power on or off, or the analog signal voltage inadvertently exceeds the supply rails during powered operation. All channel inputs have electrostatic discharge protection.
