SN74HC151N datasheet by Texas Instruments

SN74HC151N Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74HC151N?
  The maximum frequency of operation for the SN74HC151N is 40 MHz.
• How do I ensure that the SN74HC151N is properly powered?
  The SN74HC151N requires a single 5V power supply (VCC) and a ground connection (GND). Ensure that the power supply is stable and within the recommended operating range of 4.5V to 5.5V.
• What is the maximum current that the SN74HC151N can sink or source?
  The SN74HC151N can sink or source up to 6 mA of current per output pin.
• How do I handle the enable inputs (E1 and E2) to ensure proper operation?
  The enable inputs (E1 and E2) must be connected to a valid logic level (either VCC or GND) to ensure proper operation. Leaving these inputs floating can cause unpredictable behavior.
• What is the propagation delay of the SN74HC151N?
  The propagation delay of the SN74HC151N is typically around 10 ns to 15 ns, depending on the operating conditions and load capacitance.
