SN74HC266DR datasheet by Texas Instruments

SN74HC266DR Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74HC266DR?
  The maximum frequency of operation for the SN74HC266DR is 30 MHz.
• Can I use the SN74HC266DR in a 5V system?
  Yes, the SN74HC266DR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the output enable (OE) pin?
  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.
• What is the maximum current that the SN74HC266DR can sink or source?
  The SN74HC266DR can sink or source up to 25 mA per output pin.
• Can I use the SN74HC266DR in a 3.3V system?
  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.
