The J and K inputs must be held constant while the clock is high. Data is transfered to the outputs on the falling edge of the clock pulse. e This configuration is nonstable; that is, it will not persist when the preset and/or clear inputs return to their inactive (high) level. Q0 e The output logic level before the indicated input conditions were es- tablished. Toggle e Each output changes to the complement of its previous level on each complete active high level clock pulse. C1995 National Semiconductor Corporation RRD-B30M105/Printed in U. S. A.

Absolute Maximum Ratings (Note) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications. Supply Voltage 7V Input Voltage 5.5V Operating Free Air Temperature Range DM54 and 54 b55§Ct o a125§C DM74 0 §Ct o a70§C Storage Temperature Range b65§Ct o a150§C Note: The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaran- teed. The device should not be operated at these limits. The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings. The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation.

Note 2: All typicals are at V CC e 5V, T A e 25§C. Note 3: Not more than one output should be shorted at a time. Note 4: With all outputs open, I CC is measured with the Q and Q outputs high in turn. At the time of measurement the clock input is grounded. Note 5: Clear is measured with preset high and preset is measured with clear high. Note 6: TA e 25§C and V CC e 5V.
