M74HC244TTR Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the M74HC244TTR is 50 MHz, but it can vary depending on the output load and supply voltage.
-
It's recommended to tie the OE pin to VCC or a logic high during power-up and power-down to prevent unwanted output transitions.
-
The recommended output termination is a 10 kΩ to 100 kΩ pull-up or pull-down resistor, depending on the application and load requirements.
-
Yes, the M74HC244TTR can be used as a level translator, but ensure that the input voltage and output voltage are within the recommended operating ranges.
-
To minimize power consumption, use a low-power mode, reduce the clock frequency, and minimize the output load capacitance.
