ABSTRACT:
A circuit for protecting against damage from an electrostatic discharge (ESD). The circuit provides protection by minimizing a voltage difference between a main voltage line and a TTL voltage line. This is accomplished with a bypass to a main ground voltage line in the case of a positive overvoltage, and a bypass to a main supply voltage line in the case of a negative overvoltage. In order to equalize the voltage between the main supply voltage line and the TTL supply voltage line, the circuit also utilizes a metal gate N-channel field transistor and a gate diode active transistor connected in parallel between the main and TTL supply voltage lines. A pair of metal gate N-channel field transistors is also connected in parallel between the main and TTL ground voltage lines in order to equalize the voltage between the main and TTL ground voltage lines.
