ABSTRACT:
An overvoltage detector circuit for connection to an input terminal of a microcomputer device or the like employs a bistable latch with two inputs, one connected to a reference potential and the other to the input terminal. When the inputs are gated, the latch flips to one state if the terminal is at an overvoltage, or the other state if the terminal is at zero or logic-1. This circuit may be used to institute a test mode for the microcomputer.
