74HC125N (Quad Buffer / Line Driver / 3State) IRF3315 all the cathode connections ofIntroduction : 74HC125N (Quad 3 State Buffer) 74HC125 is a quad buffer line driver with 3 state outputs controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high impedanceOFF state. Inputs include clamp diodes which enable the use of current limiting resistors tointerface inputs to voltages in excess of VCC. Features : Propagation Delay Time: 100 ns at 2V 17 ns at 6V at 25C. No. of Gates: 4. Output Current: 5. 2
