The maximum operating frequency of the SN74LS645-1DWR is 30 MHz, but it can vary depending on the specific application and system design.
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 specified temperature range of -40°C to 85°C.
The recommended power-on sequence for the SN74LS645-1DWR is to apply power to the VCC pin before applying any input signals, and to ensure that the power supply voltage is stable and within the specified range before enabling the device.
To handle bus contention 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 is properly synchronized and prioritized to prevent conflicts.
The maximum capacitive load that the SN74LS645-1DWR can drive is 100 pF, but it can vary depending on the specific application and system design. It is recommended to consult the datasheet and application notes for more information.
