High Temperature Quad Analog Switch

HT1204

The HT1204 monolithic

quad analog

switch

consists

of

four

independently controlled switches capable of switching either analog

or digital signals over an extremely wide temperature range.

It is

fabricat

ed with Honeywell’s dielectrically isolated high temperature

HTMOS

™ linear process, and is designed specifically for use in

systems operating in sever high temperature environments. All parts

are burned in at 250ºC.

These switches provide guaranteed performance over the full -55 to

+225ºC temperature range.

Typically, parts will operate up to +300ºC for a year, with derated performance.

High

temperature applications such as signal gating, chopping, modulation, demodulation, and multiplexing are all possible with

the HT1204.
