The recommended operating voltage range for the 74HC123PW,118 is 2.0 V to 6.0 V.
To ensure the 74HC123PW,118 is properly powered, connect the VCC pin to a stable power supply, and decouple the power supply lines with capacitors to reduce noise and voltage spikes.
The maximum frequency of operation for the 74HC123PW,118 is 25 MHz at 6.0 V and 10 MHz at 2.0 V.
Unused inputs of the 74HC123PW,118 should be connected to VCC or GND through a resistor to prevent floating inputs and reduce power consumption.
The maximum current that the 74HC123PW,118 can sink or source is 25 mA per output pin.
