Product specification
Octal D-type flip-flop with reset; positive
edge-trigger; open drain outputs
74HCT7273
DC CHARACTERISTICS
Over recommended operating conditions; voltages are referenced to GND (ground=0V).
Note
1. The value off additional quiescent supply current (
∆ICC) for a unit load of 1 is given in the specifications. To determine
∆ICC per input, multiply this value by the unit load coefficient shown in Table 1.
