Note 16:

Absolute maximum ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications are not ensured when

operating the device at absolute maximum ratings.

Note 17: Rate of voltage change must be less than 0.5V/ms.

Note 18: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.

Note 19: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G ports TRI-STATE

and tied to ground, all outputs low and tied to ground.

Note 20: Pins G6 and RESET are designed with a high voltage input network for factory testing. These pins allow input voltages greater than VCC and the pins will

have sink current to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC). The effective

resistance to VCC is 750Ω (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.

Note 21: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
