SN74HC244DWR Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the SN74HC244DWR is 40 MHz.
-
Yes, the SN74HC244DWR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
-
The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
-
The SN74HC244DWR can sink or source up to 25 mA per output pin.
-
Yes, the SN74HC244DWR is compatible with 3.3V systems, but the output voltage will be limited to 3.3V.
