Operating temperature range is as follows: B version: 40°C to +85°C.
2
The B chip specifications are given as typical values.
3
This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the RF input is divided down to a frequency less
than this value.
4
Guaranteed by design. Sample tested to ensure compliance.
