The maximum clock frequency for the 74HC7731D,112 is 25 MHz.
Yes, the 74HC7731D,112 is compatible with a 3.3V power supply, but ensure that the input voltage levels are within the recommended range (VCC - 0.5V to VCC + 0.5V) to maintain proper operation.
The asynchronous reset (RST) input should be asserted low (active low) to reset the device. It's recommended to use a pull-up resistor to ensure the RST input is high when not asserted, and to avoid floating inputs.
The outputs of the 74HC7731D,112 are designed to drive high-capacitive loads. To ensure signal integrity, it's recommended to use a series termination resistor (e.g., 22 ohms) and a parallel capacitor (e.g., 10 pF) at the output pins.
The 74HC7731D,112 is rated for operation up to 125°C (TJ). However, it's essential to consider the derating of the device's performance and power consumption at higher temperatures. Consult the datasheet and application notes for more information.
