SN75LBC174DWR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN75LBC174DWR is 100 MHz, but it can be used at higher frequencies with reduced signal amplitude and increased signal distortion.
  • To ensure signal integrity, use a transmission line with a characteristic impedance of 50 ohms, keep the signal traces short and away from noise sources, and use proper termination and filtering techniques.
  • Yes, the SN75LBC174DWR can be used in a 3.3V system, but the output voltage swing will be reduced, and the device may not meet the specified propagation delay and skew times.
  • The power-up and power-down sequences of the SN75LBC174DWR should be controlled to prevent bus contention and ensure proper device operation. A recommended sequence is to power up the VCC supply before the input signals, and power down the input signals before the VCC supply.
  • The recommended layout and routing for the SN75LBC174DWR include using a symmetrical layout, keeping the input and output traces short and matched, and avoiding vias and right-angle bends in the signal traces.
