The recommended operating voltage range for the SN74H102N is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unwanted behavior.
The maximum frequency of operation for the SN74H102N is typically around 30MHz, although this can vary depending on the specific application and operating conditions.
To ensure proper power supply, the SN74H102N should be powered from a clean, stable voltage source with adequate decoupling capacitors (e.g., 0.1uF ceramic capacitors) placed close to the device.
While the SN74H102N is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device's performance may be degraded.
