N-Channel Switch
This device is designed for low current DC and audio applications.
These devices provide excellent performance as input stages for
sub-picoamp instrumentation or any high impedance signal
sources. Sourced from Process 53.
Absolute Maximum Ratings* T A = 25°C unless otherwise noted
*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
