HI-222
High Frequency/Video Switch
May 1999
Features
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

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.

performance. All nonconnected pins should be tied to ground.
CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
