SN74F109D Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the SN74F109D is 40 MHz, but it can vary depending on the load capacitance and the output current.
-
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 -40°C to 85°C.
-
The recommended power-on sequence for the SN74F109D is to apply power to the VCC pin before applying any input signals, and to ensure that the input signals are stable before applying the clock signal.
-
To handle bus contention when using the SN74F109D in a multi-master bus system, it is recommended to use a bus arbiter or a bus controller to manage access to the bus, and to ensure that each master device has a unique address or identifier.
-
The maximum output current of the SN74F109D is 24 mA per output pin, but it can be limited by the total device power dissipation and the output voltage.
