(enhanced-performance implanted cmos) 1- m process ? 500-ma typical latch-up immunity at 125 c ? package options include plastic small-outline packages, ceramic chip carriers, and standard plastic and ceramic 300-mil dips description these devices contain two independent j-k positive-edge-triggered flip-flops. a low level at the preset (1pre or 2pre ) or clear (1clr or 2clr ) input 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 inputs 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 tying j high. they also can perform as d-type flip-flops if j and k are tied together. the 54ACT11109 is characterized for operation over the full military temperature range of ? 55 c to 125 c. the 74act11109 is characterized for operation from ? 40 c to 85 c. function table inputs outputs pre clr clk j k q q l h x x x h l h lxxxl h l lxxxh ? h ? h h lll h h h h l toggle h h lhq 0 q 0 h h hhh l h h l x x q 0 q 0 ? this configuration is nonstable; that is, it will not persist when either pre or clr returns to the inactive (high) level. 54ACT11109 ...j p ackage 74act11109 ...d or n p ackage (top view) 54ACT11109 . . . fk package (top view) nc ? no internal connection 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 1pre 1q 1q gnd 2q 2q 2pre 2clk 1clk 1k 1j 1clr v cc 2clr 2j 2k 3 2 1 20 19 910111213 4 5 6 7 8 18 17 16 15 14 2j 2k nc 2clk 2pre 1k 1clk nc 1pre 1q 1j nc 2q 2q 2clr 1q gnd nc cc v 1clr epic is a trademark of texas instruments incorporated.
