74AC240SC Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the 74AC240SC is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
-
The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low and disabled when OE is high. You should connect OE to a logic low signal to enable the outputs, and to a logic high signal to disable them.
-
The recommended power-on sequence for the 74AC240SC is to apply power to the VCC pin before applying any input signals. This helps to prevent latch-up and ensures proper device operation.
-
Yes, the 74AC240SC is compatible with 5V systems, but you should ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V) to prevent damage to the device.
-
To prevent bus contention, you should ensure that only one device is driving the bus at a time. You can use the output enable (OE) pin to disable the outputs of the 74AC240SC when it's not supposed to be driving the bus.
