Note 1 Stresses above those listed under ‘‘Absolute Maximum Ratings’’ may cause permanent damage to the device This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the operational sections of the specification is not implied Exposure to absolute
maximum rating conditions for extended periods may affect device reliability
Note 2 The standby current of
mode is exited by depressing one of the input keys
Note 3 The clock rate used to program the NM95HS01 02 is generally less than the normal operating mode clock rate and should be temporarily reduced as
necessary to meet the programming specifications shown here For example a generator might normally operate at 4 MHz but should be programmed at
