SN74AHCT273NSR Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the SN74AHCT273NSR is 4.5V to 5.5V, with a typical voltage of 5V.

  • It is recommended to power up the VCC pin before applying any input signals, and to power down the VCC pin after removing all input signals. This ensures proper device operation and prevents latch-up or other unexpected behavior.

  • The maximum clock frequency that the SN74AHCT273NSR can handle is 100 MHz, although this may vary depending on the specific application and operating conditions.

  • It is recommended to use a termination resistor (e.g. 50 ohms) at the output of the device to prevent signal reflections and ensure proper signal integrity.

  • While the SN74AHCT273NSR is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the device's performance and functionality may be degraded, and the output voltage levels may not meet the required specifications.
