SN75ALS170ADW datasheet by Texas Instruments

SN75ALS170ADW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN75ALS170ADW?
  The maximum operating frequency of the SN75ALS170ADW is 100 MHz, but it can be used at higher frequencies with reduced signal amplitude and increased power supply noise.
• How do I ensure signal integrity when using the SN75ALS170ADW?
  To ensure signal integrity, use a low-impedance PCB layout, keep the signal traces short and away from noise sources, and use a termination resistor at the receiver end to match the impedance of the transmission line.
• Can I use the SN75ALS170ADW in a 3.3V system?
  Yes, the SN75ALS170ADW can operate from a 3.3V power supply, but the output voltage swing will be reduced, and the device may not meet the specified propagation delay and skew times.
• How do I handle the thermal dissipation of the SN75ALS170ADW?
  The SN75ALS170ADW has a thermal pad on the bottom of the package, which should be connected to a thermal plane on the PCB to dissipate heat. A thermal via or a thermal pad on the PCB can be used to improve heat dissipation.
• Can I use the SN75ALS170ADW in a high-temperature environment?
  The SN75ALS170ADW is rated for operation up to 85°C, but it can be used in higher temperature environments with derated performance. Consult the datasheet for temperature-related derating information.
