US Patent 7737749 Elastic pipeline latch with a safe mode

An elastic pipelined latch. The latch includes a control input for configuring the latch into a repeater state or a latch state, a drive component responsive to the control input and for driving an input signal through as an output signal, and a pulse width/inhibit component coupled to the drive component. The latch may further include a reset threshold component coupled to the drive component for inhibiting oscillation of the drive component, and/or a latch component for passing the present state of the input signal to the output signal when configured as the repeater state and for maintaining the previous state of the output signal during transitions of a clock signal when configured as the latch state.
