The recommended operating voltage range for the SN74AC74MDREP is 4.5V to 5.5V, as specified in the datasheet. However, it's recommended to operate the device at a fixed voltage of 5V for optimal performance.
It's recommended to follow a controlled power-up and power-down sequence to prevent unwanted latch-up or damage to the device. A slow ramp-up of the power supply voltage (typically 10-20 ms) and a slow ramp-down (typically 10-20 ms) is recommended.
The maximum clock frequency that the SN74AC74MDREP can handle is 100 MHz, as specified in the datasheet. However, the actual clock frequency may be limited by the system design, layout, and noise considerations.
Proper termination of the SN74AC74MDREP is critical to prevent signal reflections and ensure reliable operation. It's recommended to use a 50-ohm termination resistor at the output of the device, and to ensure that the PCB layout is designed to minimize signal reflections and crosstalk.
The recommended storage temperature range for the SN74AC74MDREP is -65°C to 150°C, as specified in the datasheet. It's recommended to store the device in a dry, cool place, away from direct sunlight and moisture.
