74HC151D,652 datasheet by NXP Semiconductors

74HC151D,652 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the 74HC151D,652?
  The maximum frequency of operation for the 74HC151D,652 is 40 MHz, but it can vary depending on the supply voltage and operating conditions.
• How do I ensure that the 74HC151D,652 is properly powered?
  To ensure proper power supply, connect the VCC pin to a stable 2.0 V to 6.0 V power supply, and the GND pin to a solid ground. Also, decouple the power supply with a 100 nF capacitor to reduce noise and ensure stable operation.
• What is the maximum input voltage that the 74HC151D,652 can handle?
  The maximum input voltage that the 74HC151D,652 can handle is 6.0 V. Exceeding this voltage may cause damage to the device.
• How do I handle the enable inputs (E1 and E2) to ensure proper operation?
  The enable inputs (E1 and E2) are active-low, meaning they must be pulled low to enable the device. Connect them to a logic low (GND) to enable the device, and to a logic high (VCC) to disable it.
• What is the propagation delay of the 74HC151D,652?
  The propagation delay of the 74HC151D,652 is typically around 10 ns to 20 ns, depending on the supply voltage and operating conditions.
