SN74HCT374DBR datasheet by Texas Instruments

SN74HCT374DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT374DBR?
  The maximum operating frequency of the SN74HCT374DBR is 30 MHz, but it can vary depending on the capacitive load and the output current.
• How do I ensure that the SN74HCT374DBR is properly powered?
  To ensure proper power supply, connect VCC to a 5V power source and GND to a ground plane. Also, decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the maximum output current of the SN74HCT374DBR?
  The maximum output current of the SN74HCT374DBR is 6mA per output pin, but it's recommended to limit the output current to 4mA to ensure reliable operation.
• Can I use the SN74HCT374DBR in a 3.3V system?
  No, the SN74HCT374DBR is designed to operate at 5V and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
• How do I handle the OE (Output Enable) pin?
  The OE pin is active-low, meaning it should be connected to GND to enable the outputs. When OE is high, the outputs are in a high-impedance state, which can be useful for bus-sharing applications.
