SN74ACT574DBR datasheet by Texas Instruments

SN74ACT574DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ACT574DBR?
  The maximum operating frequency of the SN74ACT574DBR is 100 MHz, but it can vary depending on the system design and capacitive load.
• How do I handle power sequencing with the SN74ACT574DBR?
  It is recommended to power up VCC before applying any input signals, and to power down VCC before removing any input signals to prevent damage to the device.
• What is the recommended termination scheme for the SN74ACT574DBR?
  The recommended termination scheme is to use a 33-ohm series resistor and a 47-pF capacitor to ground on each output pin to minimize ringing and ensure signal integrity.
• Can I use the SN74ACT574DBR in a 3.3V system?
  Yes, the SN74ACT574DBR is compatible with 3.3V systems, but the input voltage threshold may be affected, and the output voltage may not reach the full 3.3V level.
• How do I handle bus contention with the SN74ACT574DBR?
  To prevent bus contention, ensure that only one device is driving the bus at a time, and use a bus holder or pull-up/pull-down resistors to maintain a valid logic level when the bus is not being driven.
