The recommended operating voltage range for the 74HC4538D is 2.0 V to 5.5 V.
To ensure proper power supply, connect VCC to a stable voltage source and GND to a reliable ground. Decouple the power supply with a 0.1 μF capacitor to reduce noise.
The maximum frequency of operation for the 74HC4538D is 30 MHz at 5 V and 20 MHz at 3.3 V.
Unused inputs should be tied to VCC or GND through a 1 kΩ resistor to prevent floating inputs and reduce power consumption.
The maximum current that the 74HC4538D can sink or source is 25 mA per output pin.
