SN74AS32D datasheet by Texas Instruments

SN74AS32D Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AS32D?
  The maximum operating frequency of the SN74AS32D is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74AS32D is properly powered?
  To ensure proper operation, the SN74AS32D requires a stable power supply voltage (VCC) between 4.5V and 5.5V, and a ground connection (GND). Additionally, decoupling capacitors should be used to filter out noise and ensure stable operation.
• What is the input voltage threshold for the SN74AS32D?
  The input voltage threshold for the SN74AS32D is typically around 2.0V for a logic high and 0.8V for a logic low, but it can vary depending on the specific application and operating conditions.
• Can I use the SN74AS32D in a 3.3V system?
  Yes, the SN74AS32D can be used in a 3.3V system, but it may not operate at its maximum frequency and may have reduced noise margins. It's recommended to check the datasheet and application notes for specific guidance on using the device in a 3.3V system.
• How do I handle unused inputs on the SN74AS32D?
  Unused inputs on the SN74AS32D should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
