CD74HC153E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC153E?
  The maximum frequency of operation for the CD74HC153E is typically around 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure proper power sequencing when using the CD74HC153E?
  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 latch-up and ensures reliable operation.
• What is the recommended operating voltage range for the CD74HC153E?
  The recommended operating voltage range for the CD74HC153E is 2V to 6V, with a typical operating voltage of 5V. Operating outside of this range may affect the device's performance and reliability.
• How do I handle the enable inputs (E1 and E2) when not in use?
  When the enable inputs (E1 and E2) are not in use, it is recommended to tie them to a logic high (VCC) or a logic low (GND) to prevent floating inputs and ensure proper device operation.
• What is the maximum input current that the CD74HC153E can handle?
  The maximum input current that the CD74HC153E can handle is typically around 1 mA. Exceeding this limit may cause damage to the device or affect its performance.
