NOTES:
1.0
Operation of the device at these or any other condition beyond those listed under Operating Specifications is not implied.
Exposure to Absolute Maximum Rating conditions for extended periods of time may affect device reliability.
2.0
Requires external regulation and supply decoupling. (22 uF, 330 pF)
3.0
3db loop response.
4.0
50-ohm load biased to 1.3 volts.
5.0
Entry into Free Run doesn’t meet requirement for initial 2.33 seconds of self-timing.
6.0
If the selected reference is removed system response to the ALARM must be less than 10µs.
