| TECHNICAL DATA IN7472 AND-Gated J-K Master-Slave FlipFlops with Reset and Clear LOGIC DIAGRAM ORDERING INFORMATION IN7472N Plastic IN7472D SOIC TA = -10 to 70 C for all packages PIN ASSIGNMENT PIN 14 =VCC PIN 7 = GND NC - No internal connection FUNCTION TABLE Inputs Reset L H L H H H H Clear H L L H H H H Clock X X X J X X X L H L H K X X X L L H H Output Q H L H * Q L H H* Q0 L H Q0 H L TOGGLE X =don't care Q0 = the level of Q before the indicated input conditions were established. TOGGLE: Each output changes to the complement of its previous level on each active transition (pulse) of the clock. * This configuration is nonstable; that is, it will not persist whenpreset and clear inputs return to their inactive (high) level. 1 IN7472 MAXIMUM RATINGS* Symbol VCC VIN IOL Tstg * Parameter Supply Voltage Input Voltage Low Level Output Current Storage Temperature Range Value 7.0 5.5 16 -65 to +150 Unit V V mA C Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.

Note 1: With outputs open, ICC is measured with the Q and Q outputs high in turn. At the time of measurement, the clock input is grounded. 3 IN7472 AC ELECTRICAL CHARACTERISTICS (T = 25C, VCC = 5.0 V, CL = 15 pF, RL = 390 , Input tr = tf = 10 ns) Symbol tPLH tPHL tPLH tPHL tPLH tPHL Parameter Propagation Delay Time, Low to High Level Output (from Reset to Q) Propagation Delay Time, High to Low Level Output (from Reset to Q) Propagation Delay Time, Low to High Level Output (from Clear to Q) Propagation Delay Time, High to Low Level Output (from Clear to Q) Propagation Delay Time, Low to High Level Output (from Clock to Q or Q) Propagation Delay Time, High to Low Level Output (from Clock to Q or Q) Min Max 25 40 25 40 25 40 Unit ns ns ns ns ns ns Figure 1.
