NOTES FOR DS80C323 DC ELECTRICAL CHARACTERISTICS (continued)
All parameters apply to both commercial and industrial temperature operation unless otherwise noted. Specifications to -40°C
are guaranteed by design and are not production tested. Device operating range is 2.7V to 5.5V. DC electrical specifications are
for operation 2.7V to 3.3V.

Port 0 is dedicated as an address bus on the DS80C323. Peak current occurs near the input transition point of
the latch, approximately 2V.
latch bit is set to 1. This is only the current required to hold the low level; transitions from 1 to 0 on an I/O pin
will also have to overcome the transition current.
