Total Current into V
DC Electrical Characteristics
Note 1 Rate of voltage change must be less then 0 5 V ms
Note 2 Supply current is measured after running 2000 cycles with a square wave CKI input CKO open inputs at rails and outputs open
Note 3 The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations by bringing CKI high Test conditions All inputs tied to V
ports in the TRI-STATE mode and tied to ground all outputs low and tied to ground The clock monitor is disabled
Note 4 The user must guarantee that D2 pin does not source more than 10 mA during RESET If D2 sources more than 10 mA during reset the device will go into
programming mode
Note 5 Pins G6 and RESET are designed with a high voltage input network for factory testing These pins allow input voltages greater than V
have sink current to V
