Specifications subject to change without notice.
Operating temperature range is as follows: B Version: –40°C to +85°C.
The B Chip specifications are given as typical values.
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.
Guaranteed by design. Sample tested to ensure compliance.
