74ACT11245DWR datasheet by Texas Instruments

74ACT11245DWR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74ACT11245DWR?
  The recommended operating voltage range for the 74ACT11245DWR is 4.5V to 5.5V, as specified in the datasheet. However, it's recommended to operate the device at a fixed voltage of 5V for optimal performance.
• How do I handle the input pins when they are not in use?
  When the input pins are not in use, it's recommended to tie them to a valid logic level (either VCC or GND) to prevent them from floating. This helps to prevent unwanted switching and reduces power consumption.
• What is the maximum frequency of operation for the 74ACT11245DWR?
  The maximum frequency of operation for the 74ACT11245DWR is typically limited by the propagation delay of the device, which is around 3.5ns. However, the actual maximum frequency of operation depends on the specific application and the load capacitance of the output pins.
• How do I ensure signal integrity when using the 74ACT11245DWR in a high-speed application?
  To ensure signal integrity when using the 74ACT11245DWR in a high-speed application, it's recommended to use a low-impedance output driver, minimize the length of the output traces, and use a termination resistor at the receiving end to match the impedance of the transmission line.
• Is the 74ACT11245DWR compatible with 3.3V logic levels?
  The 74ACT11245DWR is a 5V device, but it can be used with 3.3V logic levels as long as the input voltage is within the recommended operating range of 4.5V to 5.5V. However, the output voltage levels may not be compatible with 3.3V logic levels, and level translation may be required.
