SN74LS396N datasheet by Texas Instruments

SN74LS396N Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS396N can handle?
  The maximum clock frequency of the SN74LS396N is typically around 10 MHz, but it can vary depending on the specific application and operating conditions. It's recommended to check the device's timing specifications and perform thorough testing to ensure reliable operation at higher frequencies.
• How do I ensure proper power sequencing when using the SN74LS396N?
  To ensure proper power sequencing, it's recommended to power up the VCC pin before applying any input signals, and to power down the VCC pin last. Additionally, it's a good idea to use a power-on reset circuit to ensure that the device is properly initialized during power-up.
• What is the recommended operating temperature range for the SN74LS396N?
  The recommended operating temperature range for the SN74LS396N is 0°C to 70°C. However, the device can operate over a wider temperature range of -40°C to 85°C, but with reduced performance and reliability.
• How do I handle bus contention when using the SN74LS396N?
  To handle bus contention, it's recommended to use a bus buffer or a bus transceiver to isolate the SN74LS396N from other devices on the bus. Additionally, it's a good idea to use a pull-up or pull-down resistor on the bus to ensure that it is properly terminated.
• What is the maximum input voltage that the SN74LS396N can tolerate?
  The maximum input voltage that the SN74LS396N can tolerate is 5.5V. Exceeding this voltage can cause damage to the device or affect its reliability.
