NOTES:

1. Typical values are for TA = 25oC.

2. IOL = IOH = 1µA.

3. Operating current is measured at 200kHz or VDD = 5V and 400kHz for VDD = 10V in a CDP1800-series microprocessor system, with

open outputs.

Operating Conditions At TA = Full Package-Temperature Range. For maximum reliability, operating conditions should be selected so

that operation is always within the following ranges:
