CD74HC377E datasheet by Texas Instruments

CD74HC377E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC377E?
  The CD74HC377E can operate at frequencies up to 40 MHz.
• How do I ensure that the outputs are not corrupted during power-up or power-down?
  To prevent output corruption during power-up or power-down, it is recommended to use a pull-up or pull-down resistor on the output pins, and to ensure that the input signals are stable before the power supply reaches the recommended operating voltage.
• Can I use the CD74HC377E in a 5V system?
  Yes, the CD74HC377E is compatible with 5V systems, but it is recommended to use a voltage regulator to ensure a stable 5V supply, and to follow proper power-up and power-down sequencing to prevent output corruption.
• How do I handle the asynchronous reset input (MR) during power-up?
  It is recommended to tie the asynchronous reset input (MR) to VCC through a pull-up resistor to ensure that the device is properly reset during power-up. This will prevent the device from entering an unknown state.
• What is the recommended capacitive load for the CD74HC377E?
  The recommended capacitive load for the CD74HC377E is 50 pF or less. Exceeding this value may affect the device's performance and reliability.
