The G441 has a normally closed function. The G442 has a normally open function. ombining low on-resistance (, typ.) with high speed (t ON 1 ns, typ.), the G441/442 are ideally suited for upgrading G21A/22 sockets. harge injection has been minimized on the drain for use in sample-and-hold circuits. To achieve high voltage ratings and superior switching performance, the G441/442 are built on s high-voltage silicon-gate process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks input voltages to the supply levels when off.
