N-Channel Switch
This device is designed for low level analog switching, sample
and hold circuits and chopper stabalized amplifiers. Sourced
from Process 51. See J111 for characteristics.
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
