FLIP-FLOP CIRCUIT WITH SHORT PROPOGATION DELAY

摘要

Input and output terminals of two inverters (1, 2) connected between corresponding data input terminals (7, 8) and corresponding data output terminals (12, 11) are cross-connected. Latch switches (3, 4) are inserted between the inverters and the corresponding data input terminals. Hold switches (5, 6) are inserted in the cross-connected portion of the two inverters. The latch switches (3, 4) are turned on/off in synchronism with a latch input (9) while the hold switches (5, 6) are turned on/off in synchronism with a hold input (10).
