Abstract
A circuit for detecting an input signal, the circuit having an input node and an output node, includes a first latch having a set input coupled to the input node, for detecting falling transitions at the input node. A second latch having a set input coupled to the input node, detects rising transitions at the input node. A first logic device, responsive to outputs of the first and second latches, detects that an input signal has been received at both the first and second latches. A second logic device, responsive to a complement output of both the first and second latches, resets both the first and second latches.
