No Preview Available ! HD74HC73 Dual J-K Flip-Flops (with Clear) Description The flip-flop is edge sensitive to the clock input and change state on the negative going transition of the clock pulse. Each flip-flop has independent, J, K, clock, and clear inputs and Q and Q outputs. Clear is independent of the clock and accomplished by a low level on the input. Features • High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C) Function Table Inputs Outputs Clear Clock J K Q Q LX X X L H H L L No change H LHL H H HL H L H H H Toggle HL XX No change H H X X No change H X X No change 1 page 19.20 20.32 Max 14 8 1 1.30 7 2.39 Max Unit: mm 7.62 2.54 ± 0.25 0.48 ± 0.10 0.25 + – 0.10 0.05 0° – 15° Hitachi Code JEDEC EIAJ Weight (reference value) DP-14 Conforms Conforms 0.97 g 5 Page
