Ensure the desired supply voltage is within the range specified in the Recommended Operating Conditions. The supply voltage sets the device's electrical characteristics as described in the Electrical Characteristics.
The positive voltage supply must be capable of sourcing current equal to the total current to be sourced by all outputs of the SNx4BCT374 plus the maximum static supply current, ICC, listed in Electrical Characteristics and any transient current required for switching. The logic device can only source as much current as is provided by the positive supply source.
The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the SNx4BCT374 plus the maximum supply current, ICC, listed in Electrical Characteristics, and any transient current required for switching. The logic device can only sink as much current as can be sunk into its ground connection.
The SNx4BCT374 can drive a load with a total capacitance less than or equal to 50 pF while still meeting all of the datasheet specifications. Larger capacitive loads can be applied, however it is not recommended to exceed 50 pF.
The SNx4BCT374 can drive a load with total resistance described by RL ≥ VO / IO, with the output voltage and current defined in the Electrical Characteristics table with VOH and VOL. When outputting in the high state, the output voltage in the equation is defined as the difference between the measured output voltage and the supply voltage at the VCC pin.
Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear and Logic (SLL) Packages and Devices.
