Integrated circuit driver for serial bus having output overvoltage protection |
摘要 |
An integrated circuit driver for high and low lines in a bus. The driver comprises first and second current sources connected to high and low voltage sources, respectively, and first and second transistor circuits for blocking voltage spikes higher or lower than the voltages provided by the high and low voltage sources. The first current source and the first transistor circuit are series connected between the high voltage supply and the high line, and the second current source and the second transistor circuit are series connected between the low voltage source and the low line.
