CD74AC112E datasheet by Texas Instruments

CD74AC112E Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74AC112E?
  The recommended operating voltage range for the CD74AC112E is 2V to 6V, with a typical voltage of 5V.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low and disabled when OE is high. You should connect OE to a logic low signal to enable the outputs and a logic high signal to disable them.
• What is the maximum clock frequency that the CD74AC112E can handle?
  The maximum clock frequency that the CD74AC112E can handle is 100 MHz, but this can vary depending on the operating voltage and load conditions.
• How do I ensure that the CD74AC112E is properly powered and bypassed?
  To ensure proper operation, you should provide a stable power supply to the CD74AC112E, with a decoupling capacitor (typically 0.1 μF) connected between the power supply pins (VCC and GND) and the device. You should also consider adding additional bypass capacitors to the power supply lines to reduce noise and ensure reliable operation.
• What is the propagation delay time for the CD74AC112E?
  The propagation delay time for the CD74AC112E is typically around 10 ns, but this can vary depending on the operating voltage, temperature, and load conditions.
