The recommended operating voltage range for the SN54AS74AJ is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
To ensure reliable operation in high-temperature environments, it's recommended to derate the device's power consumption and ensure good thermal management, such as using a heat sink or providing adequate airflow.
The maximum clock frequency that the SN54AS74AJ can handle is 100 MHz, although this may vary depending on the specific application and operating conditions.
While the SN54AS74AJ 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 reduced, and it's recommended to consult the datasheet and application notes for specific guidance.
The asynchronous reset input (CLR) on the SN54AS74AJ should be tied to VCC through a pull-up resistor or connected to a reset signal that meets the device's input requirements. This ensures that the device is properly reset and initialized during power-up or reset conditions.
