The maximum frequency of operation for the MM74HC138M is typically around 25 MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper operation, the MM74HC138M should be powered from a stable, low-noise power supply, and decoupling capacitors (e.g., 0.1 μF) should be placed as close as possible to the device's power pins.
The MM74HC138M outputs can source or sink up to 25 mA of current, but this should be limited to 15 mA for reliable operation.
The enable inputs (E1, E2, E3) should be driven with a valid logic level (either high or low) to ensure proper operation. If an enable input is left floating, the device may not function correctly.
The propagation delay of the MM74HC138M is typically around 10-15 ns, but this can vary depending on the specific application and operating conditions.
