The recommended operating voltage range for the CD54HC123F3A is 2V to 6V.
To ensure proper power supply, connect VCC to a stable voltage source, and GND to a reliable ground. Decouple the power supply with a 0.1uF capacitor to reduce noise.
The CD54HC123F3A can handle clock frequencies up to 25MHz.
The CD54HC123F3A can be reset by applying a low signal to the MR (Master Reset) pin.
The propagation delay time for the CD54HC123F3A is typically around 10ns to 15ns, depending on the operating voltage and temperature.
