SN74ALS245ADWRG4 datasheet by Texas Instruments

SN74ALS245ADWRG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ALS245ADWRG4?
  The maximum operating frequency of the SN74ALS245ADWRG4 is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the SN74ALS245ADWRG4?
  To ensure signal integrity, use proper PCB layout techniques, such as keeping signal traces short, using ground planes, and minimizing crosstalk. Also, use series termination resistors and/or parallel termination capacitors to reduce signal reflections.
• Can I use the SN74ALS245ADWRG4 in a 3.3V system?
  Yes, the SN74ALS245ADWRG4 is compatible with 3.3V systems, but ensure that the input voltage does not exceed the maximum rating of 4.5V. Also, note that the output voltage may not reach the full 3.3V level due to the internal voltage drop.
• How do I handle power sequencing when using the SN74ALS245ADWRG4?
  To avoid latch-up or damage, ensure that the power supply voltage (VCC) is applied before the input signals. Also, ensure that the power supply voltage is stable and within the recommended operating range before applying input signals.
• What is the recommended operating temperature range for the SN74ALS245ADWRG4?
  The recommended operating temperature range for the SN74ALS245ADWRG4 is -40°C to 85°C. However, the device can operate up to 125°C with reduced performance and reliability.
