The 74HC125, 74HCT125 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 impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Mixed 5 V and 3.3 V applications Improved current drive and voltage level of signals Improved signal integrity for complex layouts Wide supply voltage range Low propagation delay TTL input options 3-state output options Overvoltage tolerant options Registered options Key applications LCD TV Cell phones Industrial monitoring STB
