SN74HC151PW datasheet by Texas Instruments

SN74HC151PW Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74HC151PW?
  The maximum frequency of operation for the SN74HC151PW is 40 MHz.
• How do I ensure that the SN74HC151PW is properly powered?
  The SN74HC151PW requires a single 2-V to 6-V power supply, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper operation.
• What is the propagation delay time for the SN74HC151PW?
  The propagation delay time for the SN74HC151PW is typically around 10 ns to 20 ns, depending on the operating frequency and voltage.
• Can I use the SN74HC151PW in a 3.3-V system?
  Yes, the SN74HC151PW is compatible with 3.3-V systems, but ensure that the input signals are within the recommended voltage range of 0.8 V to 2.4 V.
• How do I handle the enable inputs (E1 and E2) for proper operation?
  The enable inputs (E1 and E2) must be tied to a valid logic level (either VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
