Description
The HI-222 is a high frequency analog switch that
complements the Harris family of high speed op amps and
buffers. Fabricated with our Dielectric Isolation process and
using silicon gate technology, many key parameters have
been enhanced.
Crosstalk and off isolation are optimized with a T-switch
configuration and the use of nonconnected pins for extended
shielding. Other features of the HI-222 include wideband
operation, low r
ON
, fast switching speeds and low differential
gain and phase. The characteristics of this TTL compatible
device make it ideal for designs where improved switching
performance is required.
The primary application of this dual SPST switch is the
routing of high frequency signals in equipment ranging from
video production mixers to military RF circuits.
For specifications on HI-222/883, refer to Harris Military
Analog Data book.

NOTES:
2. As with all semiconductors, stresses listed under "Absolute Maximum Ratings" may be applied to devices (one at a time) without resulting
in permanent damage. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability. The conditions listed under "Electrical Specifications" are the only conditions recommended for satisfactory operation.
