Note 2:
Rate of voltage change must be
<
10V/ms.
Note 3:
Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4:
The HALT mode will stop CKI from oscillating in the RC and crystal configurations. HALT test conditions: L, and G0..G5 ports configured as outputs and set
high. The D port set to zero. All inputs tied to V
CC
. The comparator and the Brown Out circuits are disabled.
Note 5:
Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than V
and the pins will have sink current
to V
when biased at voltages greater than V
(the pins do not have source current when biased at a voltage below V
CC
). The effective resistance to V
CC
is 750
(typical). These two pins will not latch up. The voltage at the pins must be limited to
<
14V.
Note 6:
The Resistor values are for R/C only.
