FEATURES APPLICATIONS
HT1204
The HT1204 monolithic quad analog switch consists of
four independently controlled switches capable of switch-
ing either analog or digital signals over an extremely wide
temperature range. 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 perfor-
mance.
High temperature applications such as signal
gating, chopping, modulation, demodulation and multi-
plexing are all possible with the HT1204.
