Nuclear Event Detector

Note: All dimensions in inches.

1. Standby mode is the normal state of the device, defined as having the NED output (pin 2) in the “high” state.

2. Operational mode is in effect during the timeout period of the NED signal, characterized by having the NED output in the “low”

state, causing the greatest current draw of the device.

3. BIT electrical characteristics are not guaranteed over the radiation range.

4. BIT may not meet specification when only a resistor is used to adjust the detection level. To use BIT in this situation, it is

advised that a series resistor/capacitor combination is used.

5. Guaranteed but not tested over temperature. Time delay, t

pulse to the falling edge of the NED output at approximately 10 times the detection level.
