In hard disc drive (HDD) applications, there is often a need for input buffers that can operate at a variety of voltages (i.e., 1.8V, 2.5V, and 3.3V) as well as tolerate high voltages (i.e., 5V). Traditional buffers, however, usually lack the ability to operate at these varying voltages and lack the ability to tolerate high voltages. Here, a buffer is provided that fits this criteria through the use of a switching circuit and an anti-saturation circuit (as well as other circuitry). |
