CD74HC137PW Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC137PW?
  The maximum frequency of operation for the CD74HC137PW is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure proper power sequencing when using the CD74HC137PW?
  To ensure proper power sequencing, it is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This helps to prevent unwanted latch-up or damage to the device.
• What is the recommended operating voltage range for the CD74HC137PW?
  The recommended operating voltage range for the CD74HC137PW is 2V to 6V, with a typical operating voltage of 5V. Operating the device outside of this range may affect its performance and reliability.
• How do I handle unused inputs on the CD74HC137PW?
  Unused inputs on the CD74HC137PW should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
• What is the maximum output current that the CD74HC137PW can sink or source?
  The maximum output current that the CD74HC137PW can sink or source is 25 mA per output pin, with a total device current limit of 100 mA.
