The recommended operating voltage range for TC74HC126AF(F) is 2V to 6V, with a typical voltage of 5V.
When the input pins are not in use, they should be tied to VCC or GND to prevent them from floating, which can cause unpredictable behavior.
The maximum frequency of operation for TC74HC126AF(F) is 10MHz, but this can vary depending on the operating voltage and load conditions.
Yes, TC74HC126AF(F) can be used in a 3.3V system, but the output voltage will be limited to around 3.1V, and the device may not be able to drive heavy loads.
To ensure that the output signals are not distorted, the output pins should be terminated with a load impedance of 50 ohms or higher, and the output voltage should not exceed the recommended maximum value.
