The SN74LS06DBR can operate over a temperature range of 0°C to 70°C.
To ensure the output voltage is within the specified range, make sure the input voltage is within the recommended range (4.75V to 5.25V), and the output is properly terminated with a load resistance of 1 kΩ or higher.
The SN74LS06DBR can sink up to 24 mA and source up to 12 mA per output.
To ensure proper operation, power up the VCC pin before applying any input signals, and power down the VCC pin after removing all input signals.
To minimize noise and ensure proper operation, keep the input and output traces short and away from each other, and use a solid ground plane to reduce electromagnetic interference (EMI).
