The TSC312/313 provides two fast, edge-triggered flip-flops in a single package. Separate logic inputs allow them to be used independently as J-K or set-reset flip-flops. Clock inputs present only 1 unit load. For use in new designs, the non-edge sensitive 313 is reoornrnended.
The features of TSC312 can be summarized as (1)can be set or reset with clock high or low; (2)clock inputs are only 1 unit load; (3)J-K or S-R operation (313J-K master/slave); (4)fast-5 mHz typical toggle rate; (5)edge-sensitive operation (on 312); (6)non-edge sensitive operation (on 313).
The TSC312 is typical applicated in many places. The 312 triggers on the falling edge of the olook pulse, which most fall faster than 3V/microsecond for proper operation. Direct set and reset may be accomplidted at any time, with the clock either high or low. The 313 was developed to give the HiHIL. logic designer the most flexible dual flip-flop package po iblet The 313 is eapable of J-K master/slave or S-R operation with set and reset inputs. The timing diagram shown on page 28 indicates the operation sequenoe for J-K masser/slave operation. The positive going edge of the clock. pulse inhibits the slave and enables data transfer to the master (master/slave thresholds are offset to ensure proper inhibition and enable). The falling edge inhibits the master and allows data transfer to the slave. Direct set or reset may be accomplished at any time, with the clock pulse either high or low. For reliable operation the following 313 timing recommendations should be followed. They apply across both the applieable temp range and VCC spread.
