SCLS769B July 2019 – September 2019 SN74HCS32-Q1
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 supply must be capable of sourcing current equal to the total current to be sourced by all outputs of the SN74HCS32-Q1 plus the maximum supply current, ICC, listed in the Electrical Characteristics. The logic device can only source or sink as much current as it is provided at the supply and ground pins, respectively. Be sure not to exceed the maximum total current through GND or VCC listed in the Absolute Maximum Ratings.
The SN74HCS32-Q1 can drive a load with a total capacitance less than or equal to 50 pF connected to a high-impedance CMOS input while still meeting all of the datasheet specifications. Larger capacitive loads can be applied, however it is not recommended to exceed 70 pF.
Total power consumption can be calculated using the information provided in CMOS Power Consumption and Cpd Calculation.
Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear and Logic (SLL) Packages and Devices.
The maximum junction temperature, TJ(max) listed in the Absolute Maximum Ratings, is an additional limitation to prevent damage to the device. Do not violate any values listed in the Absolute Maximum Ratings. These limits are provided to prevent damage to the device.
