The maximum frequency of operation for the SN74HC266DR is 30 MHz.
Yes, the SN74HC266DR 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 should be connected to a logic low (GND) to enable the outputs. If left unconnected, the OE pin will float high, disabling the outputs.
The SN74HC266DR can sink or source up to 25 mA per output pin.
Yes, the SN74HC266DR is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. Ensure that the input signals are also 3.3V-compatible.
