SN74HC251PWR Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the SN74HC251PWR is 40 MHz.
-
Yes, the SN74HC251PWR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
-
The enable inputs (EN1 and EN2) are active-low, meaning they must be pulled low to enable the device. You can connect them to GND or use a pull-down resistor to ensure proper operation.
-
The propagation delay of the SN74HC251PWR is approximately 10 ns, but this can vary depending on the operating frequency and load capacitance.
-
Yes, the SN74HC251PWR is compatible with 3.3V systems, but you may need to adjust the input voltage levels and ensure that the output voltage is within the recommended range.
