The maximum frequency of operation for the SN7402N is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal management practices, such as providing adequate heat sinking and ensuring good airflow around the device. Additionally, the device should be operated within its recommended operating temperature range of -40°C to 85°C.
The recommended power-on sequence for the SN7402N is to apply power to the VCC pin before applying any input signals. This helps to prevent unwanted output states during power-up.
Unused inputs on the SN7402N should be tied to a valid logic level (either VCC or GND) to prevent unwanted output states and reduce power consumption.
The maximum output current of the SN7402N is typically around 16 mA per output, but this can vary depending on the specific application and operating conditions.
