Abstract
A synchronized pulsed look-ahead circuit (10 in FIG. 1) effects look-ahead operations for a flip-flop (20). It includes a LAPP section (12) and a DATA sense and control section (14). To initiate a look-ahead operation, the LAPP section triggers in synchronism with the control edge of CLK, swtiching the LAPP line active and enabling the DATA sense and control section. While enabled, the DATA sense and control section receives DATA IN, and depending on its phase, provides the appropriate logic levels to the DATA output driver, which then provides the appropriate DATA OUT. When the flip-flop has latched the DATA and is ready to assume control of the DATA OUT line, i.e., after the associated propagation delay, the LAPP pulse is terminated and the DATA sense and control section is disabled, terminating the look-ahead operation.
