摘要：
A latch device is provided with a relay and a shadow latch. The relay has an input to accept a binary relay input signal, an input to accept a clock signal, an input to accept a shadow-Q signal, and an output to supply a binary Q signal value equal to the relay input signal value. The relay output is supplied in response to the relay input signal, the shadow-Q signal, and the clock signal. The shadow latch has an input to accept the relay input signal, an input to accept the clock signal, and an output to supply the shadow-Q signal with a value equal to an inverted Q signal value. The shadow latch output is supplied in response to the relay input signal and clock signal.
