SN54F109, SN74F109 DUAL J-K POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH CLEAR AND PRESET SDFS047A – MARCH 1987 – REVISED OCTOBER 1993 SN54F109 . . . J PACKAGE SN74F109 . . . D OR N PACKAGE (TOP VIEW) Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs 1CLR 1J 1K 1CLK 1PRE 1Q 1Q GND description These devices contain two independent J-K positive-edge-triggered flip-flops. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the J and K input meeting the setup-time requirements are transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops can perform as toggle flip-flops by grounding K and trying J high. They also can perform as D-type flip-flops if J and K are tied together. 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC 2CLR 2J 2K 2CLK 2PRE 2Q 2Q 1J 1CLR NC SN54F109 . . .
