Note: 1. Values stipulated in the electrical characteristics for the corresponding product must be used for the test conditions for the maximum and minimum
values.
2. Typical values are values for VCC1 = 5.0 V, VCC2 = 3.3 V, and an ambient temperature of +25°C.
3. Do not test more than one output at a time. The test time must not exceed 1 second.

Note: 1. Values stipulated in the electrical characteristics for the corresponding product must be used for the test conditions for the maximum and minimum
values.
2. Typical values are values for VCC1 = 5.0 V, VCC2 = 3.3 V, and at an ambient temperature of +25°C.
3. For the TTL drive inputs (VIN = 2.4 V), connect all the other inputs to VCC1 or GND.
4. Although this parameter cannot be directly measured, it is provided for calculating the total power dissipation.
5. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC, DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent current (ICCL, ICCH, and ICCZ)
∆ICC = Supply current for the high-level TTL inputs
DH = Duty cycle for the high-level TTL inputs
NT = The number of TTL inputs in DH
ICCD = Operating current due to input transition pairs (HLH or LHL)
fCP = Clock frequency for register devices (zero for non-register devices)
NCP = The number of clocks input in fCP
fi = Input frequency
Ni = The number of inputs in fi.
