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 Output Reset Clear Clock J K Q Q L H X X X H L H L X X X L H L L H X * H* X X H H L L Q0 Q0 H H H L H L H H L H L H H H H H 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 Parameter Value Unit VCC Supply Voltage 7.0 V VIN Input Voltage 5.5 V IOL Low Level Output Current 16 mA Tstg Storage Temperature Range -65 to +150 °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 = 25°C, VCC = 5.0 V, CL = 15 pF, RL = 390 Ω, Input tr = tf = 10 ns) Symbol Parameter tPLH Max Unit Propagation Delay Time, Low to High Level Output (from Reset to Q) 25 ns tPHL Propagation Delay Time, High to Low Level Output (from Reset to Q) 40 ns tPLH Propagation Delay Time, Low to High Level Output (from Clear to Q) 25 ns tPHL Propagation Delay Time, High to Low Level Output (from Clear to Q) 40 ns tPLH Propagation Delay Time, Low to High Level Output (from Clock to Q or Q) 25 ns tPHL Propagation Delay Time, High to Low Level Output (from Clock to Q or Q) 40 ns Figure 1.
