Abstract: A keyboard having N-Key Lockout and Two-Key Rollover Protection is disclosed. Each key switch of the keyboard is assigned a unique time slot in a scan cycle. A key switch actuation results in a logic "1" signal at the input of a shift register which is shifted to the output of the shift register one scan time later. Comparison of the input and output states of the shift register results in a signal which indicates when any key switch has not been actuated during the last scan cycle in order to reset a flip-flop which produces a strobe pulse to external data processing equipment. A modulus 2 counter, and other associated circuitry, inhibits the strobe pulse whenever two key switches are actuated during the same scan cycle.
