SN74ACT2228DW datasheet by Texas Instruments

SN74ACT2228DW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74ACT2228DW?
  The recommended operating voltage range for the SN74ACT2228DW is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
• How do I handle the power-up and power-down sequencing of the SN74ACT2228DW?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the maximum frequency of operation for the SN74ACT2228DW?
  The maximum frequency of operation for the SN74ACT2228DW is typically around 100 MHz, although this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74ACT2228DW is properly terminated to prevent signal reflections?
  It is recommended to use a termination resistor (e.g. 50 ohms) at the output of the device to prevent signal reflections and ensure signal integrity.
• Can I use the SN74ACT2228DW in a 3.3V system?
  Yes, the SN74ACT2228DW can be used in a 3.3V system, although the output voltage will be limited to around 3.0V. Additionally, the device's performance may be reduced at lower voltages.
