MC74AC244NG Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the MC74AC244NG is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
-
The output enable (OE) pin should be connected to a logic low (GND) to enable the outputs, and to a logic high (VCC) to disable the outputs. Leaving the OE pin floating can cause unpredictable behavior.
-
The recommended power-on sequence is to apply power to the VCC pin first, followed by the input signals, and then the output enable (OE) pin. This helps to prevent unwanted output transitions during power-up.
-
Yes, the MC74AC244NG is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply. Additionally, the input and output voltage levels should be within the recommended operating range.
-
The MC74AC244NG has a maximum junction temperature of 150°C. To ensure reliable operation, it's recommended to keep the device within a safe operating temperature range by providing adequate heat sinking and airflow.
