SN74AHC123ADBR datasheet by Texas Instruments

SN74AHC123ADBR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74AHC123ADBR can handle?
  The maximum clock frequency of the SN74AHC123ADBR is 100 MHz.
• How do I ensure that the SN74AHC123ADBR is properly powered?
  The SN74AHC123ADBR requires a power supply voltage (VCC) of 2.0 V to 5.5 V, and it is recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper power supply decoupling.
• What is the propagation delay of the SN74AHC123ADBR?
  The propagation delay of the SN74AHC123ADBR is typically 10 ns, but it can vary depending on the operating conditions and the specific application.
• Can I use the SN74AHC123ADBR in a 3.3 V system?
  Yes, the SN74AHC123ADBR is compatible with 3.3 V systems, but it is recommended to use a voltage regulator to ensure a stable power supply voltage.
• How do I handle the asynchronous reset input (MR) of the SN74AHC123ADBR?
  The asynchronous reset input (MR) of the SN74AHC123ADBR should be tied to VCC through a pull-up resistor (typically 1 kΩ to 10 kΩ) to ensure that the device is properly reset.
