The SNx4ACT244 is high-drive buffer drivers providing 24-mA current drive per channel at nominal operating specifications. It can be used as LED driver with appropriate current-limiting resistors to ground or VCC withing the device's and LED's operating characteristics.
The pullup and pulldown current limiting resistors are chosen to operate within the LED and the SNx4ACT244 device operating specifications. A 1-kΩ resistor, limits the current to less than 5 mA at 5-V VCC operation.
