HI-222

T CT DUC PRO PRODU E T E E L T O U OBS UBSTIT 83 S 8 / E 2 SIBL HI-22 POS May 1999 HI-222 High Frequency/Video Switch 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 rON , 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.
