The maximum frequency of operation for the 74HC138D,652 is 25 MHz.
Ensure that the 74HC138D,652 is powered with a stable voltage supply between 2V and 6V, and that the power supply noise is minimized to prevent malfunction.
The 74HC138D,652 can sink or source up to 25mA of current per output pin.
The enable inputs (E1, E2, E3) must be connected to a valid logic level (either VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
Yes, the 74HC138D,652 can be used as a level translator, but ensure that the input voltage levels are compatible with the device's operating voltage range.
