SN74AS181ADW datasheet by Texas Instruments

SN74AS181ADW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74AS181ADW?
  The recommended operating voltage range for the SN74AS181ADW is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
• How do I handle the asynchronous clear (CLR) input?
  The asynchronous clear (CLR) input should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) if it's not used, to prevent unwanted clearing of the arithmetic logic unit (ALU).
• What is the maximum clock frequency for the SN74AS181ADW?
  The maximum clock frequency for the SN74AS181ADW is 25 MHz, although this can vary depending on the specific application and operating conditions.
• How do I interface the SN74AS181ADW with other logic families?
  The SN74AS181ADW is a TTL-compatible device, so it can be interfaced with other TTL devices directly. For interfacing with CMOS or other logic families, level translation or buffering may be required.
• What is the power consumption of the SN74AS181ADW?
  The typical power consumption of the SN74AS181ADW is around 200 mW, although this can vary depending on the operating frequency, voltage, and load conditions.
