SN74LS138N Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the SN74LS138N is typically around 20-25 MHz, but this can vary depending on the specific application and operating conditions.
-
To ensure proper operation, the SN74LS138N should be powered with a stable 5V supply, and decoupling capacitors (e.g. 0.1uF and 10uF) should be placed close to the device to filter out noise and reduce electromagnetic interference (EMI).
-
The SN74LS138N can sink up to 24mA and source up to 12mA per output, but it's recommended to keep the current within the absolute maximum ratings to ensure reliable operation.
-
The enable inputs (E1, E2, E3) should be driven with a valid logic level (either high or low) to enable or disable the decoder outputs. Floating or undefined enable inputs can cause unpredictable behavior.
-
The propagation delay of the SN74LS138N is typically around 10-15ns, but this can vary depending on the specific application and operating conditions.
