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.
6. RST = VCC. This condition mimics operation of pins in I/O mode.
7. During a 0-to-1 transition, a one-shot drives the ports hard for two clock cycles. This measurement reflects port
in transition mode.
8. Ports 1, 2, and 3 source transition current when being pulled down externally. It reaches its maximum at
approximately 2V.
9. VIN between ground and VCC - 0.3V. Not a high-impedance input. This port is a weak address latch because
Port 0 is dedicated as an address bus on the DS80C323. Peak current occurs near the input transition point of
the latch, approximately 2V.
10. Over the industrial temperature range, this specification has a maximum value of 200
A.
11. This is the current from an external circuit to hold a logic low level on an I/O pin while the corresponding port
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.
12. Device operating range is 2.7V to 5.5V, however device is tested to 2.5V to ensure proper operation at
minimum VRST.
