N-Channel Amplifier
• This device is designed primarily for electronic switching applications such as low on resistance analog switching.
• Sourced from process 51.
Absolute Maximum Ratings* Ta=25°C unless otherwise noted
* This ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These rating are based on a maximum junction temperature of 150 degrees C.
2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
