NOTES:
1. For conditions shown as Min. or Max., use appropriate value specified above for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient temperature, and maximum loading.
3. Total supply current is the sum of the Quiescent current and the dynamic current and is calculated as follows:
ICC = ICCQ + ICCQT (NT x DT) + ICCD (fOP)
where: NT = Total # of quiescent TTL inputs
DT = AC Duty cycle – % of time high (TTL)
fOP = Operating frequency
Max.
