1.  Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may

reduce device reliability. 2. Measured in plastic DIP package, results in die form are dependent on die attach and assembly method.

  

Pad Descriptions

CLOCK INPUTS

1CLK, 2CLK (Pads 1, 13)

Clock input (HIGH-to-LOW, edge triggered)

DATA INPUTS

1K, 2K, 1J, 2J (Pads 2, 12, 3, 11)

Data inputs; flip-flops 1 and 2

OUTPUTS

1Q, 2Q, 1Q, 2Q (Pads 5, 9, 6, 7)

True flip-flop outputs and complement flip-flop outputs

3.  This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be

taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT

should be constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either

GND or VCC). Unused outputs must be left open.

CONTROL INPUTS

1PRE, 2PRE (Pads 4, 10)

Set inputs (active LOW)

1CLR, 2CLR ( Pads 15, 14)

Reset inputs (active LOW)
