SN54LS245J Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the SN54LS245J is 40 MHz.
-
No, the SN54LS245J is a 5V device and is not compatible with 3.3V systems. You may need to use a level translator or a different device that is compatible with 3.3V systems.
-
The enable inputs (G1 and G2) are active-low, meaning that they must be pulled low to enable the device. You can tie them to ground or use a pull-down resistor to enable the device.
-
The propagation delay of the SN54LS245J is approximately 10-15 ns, depending on the operating conditions and load capacitance.
-
Yes, the SN54LS245J can be used as a level translator, but it is not recommended as it is not designed for this purpose. The device is primarily intended for use as a bus transceiver.
