DC Electrical Characteristics
Note 1: Rate of voltage change must be less than 0.5V/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. Test conditions: All inputs tied to V
and tied to ground, all outputs low and tied to ground.
Note 4: Pins G6 and RESET have sink current to V resistance to V
Note 5: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
CC
are designed with a high voltage input network for factory testing. These pins allow input voltages greater than VCCand the pins will
when biased at voltages greater than VCC(the pins do not have source current when biased at a voltage below VCC). The effective
CC
is 750X (typ). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
