The maximum frequency of operation for the 74HC423D,653 is 100 MHz.
To ensure proper power supply, connect VCC to a 2.0 V to 5.5 V power source, and GND to a common ground. Decouple the power supply with a 100 nF capacitor.
The recommended operating temperature range for the 74HC423D,653 is -40°C to +125°C.
Unused inputs should be connected to VCC or GND through a 1 kΩ resistor to prevent floating inputs and reduce power consumption.
The maximum current that the 74HC423D,653 can sink or source is 25 mA per output pin.
