FAST AND LS TTL DATA
DUAL JK NEGATIVE
EDGE-TRIGGERED FLIP-FLOP
The SN54LS/74LS73A offers individual J, K, clear, and clock inputs. These
dual flip-flops are designed so that when the clock goes HIGH, the inputs are
enabled and data will be accepted. The logic level of the J and K inputs may
be allowed to change when the clock pulse is HIGH and the bistable will per-
form according to the truth table as long as minimum set-up times are ob-
served. Input data is transferred to the outputs on the negative-going edge of
the clock pulse.
