For conditions shown as Min. or Max., use appropriate value specified under DC Electrical Characteristics. 2. Per TTL driven input (VIN = 3.4V). 3. For flip-flops, ICCD is measured by switching one of the data input pins so that the output changes every clock cycle. This is a measurement of device power consumption only and does not include power to drive load capacitance or tester capacitance. 4.
