SN74LS123N Frequently Asked Questions (FAQ)

  • The maximum frequency of operation for the SN74LS123N is typically 2 MHz, but it can vary depending on the specific application and operating conditions.

  • To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device is operated within its recommended operating temperature range of 0°C to 70°C.

  • The recommended power-on sequence for the SN74LS123N is to apply power to the VCC pin first, followed by the input signals. This helps to prevent unwanted oscillations and ensures proper device operation.

  • The asynchronous reset input (MR) on the SN74LS123N should be tied to VCC through a pull-up resistor to ensure proper device operation. A 1-kΩ to 10-kΩ resistor is typically used for this purpose.

  • The maximum input voltage that can be applied to the SN74LS123N is 5.5V. Exceeding this voltage can cause damage to the device.
