SN74AHC138DBR Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the SN74AHC138DBR is 100 MHz, but it can vary depending on the specific application and operating conditions.
-
To ensure proper power supply, connect VCC to a stable 5V power source, and GND to a solid ground plane. Also, decouple the power supply with a 0.1uF capacitor to reduce noise and ensure reliable operation.
-
The SN74AHC138DBR can sink or source up to 8mA of current per output pin, but it's recommended to limit the current to 4mA or less to ensure reliable operation and prevent overheating.
-
The enable inputs (E1, E2, E3) should be driven with a valid logic level (either high or low) to ensure proper operation. Avoid floating or undefined states on these inputs, as it may cause unpredictable behavior.
-
The propagation delay of the SN74AHC138DBR is typically around 10-15ns, but it can vary depending on the specific application, operating conditions, and output load.
