SN54LS47J datasheet by Texas Instruments

SN54LS47J Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS47J can handle?
  The maximum clock frequency of the SN54LS47J is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure proper power sequencing when using the SN54LS47J?
  To ensure proper power sequencing, apply power to the VCC pin before applying any input signals, and ensure that the power supply voltage is stable before enabling the clock signal.
• What is the recommended operating temperature range for the SN54LS47J?
  The recommended operating temperature range for the SN54LS47J is 0°C to 70°C, but it can operate up to 125°C with reduced performance and reliability.
• Can I use the SN54LS47J in a 3.3V system?
  No, the SN54LS47J is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in reduced performance, incorrect operation, or even damage to the device.
• How do I handle the output enable (OE) pin when using the SN54LS47J?
  The output enable (OE) pin should be tied to GND or VCC, depending on the desired output state. Leaving the OE pin floating can cause unpredictable behavior and may result in incorrect output states.
