It is fabricated with Honeywell’s dielectrically isolated high temperature (HTMOS™) linear process, and is designed specifically for use in systems operating in severe high temperature environments. All parts are burned in at 250°C to eliminate infant mortality. These switches provide guaranteed performance over the full -55 to +225°C temperature range. Typically, parts will operate up to +300°C for a year, with derated performance. High temperature applications such as signal gating, chopping, modulation, demodulation and multiplexing are all possible with the HT1204.
