54LS47FMQB

The 54LS47FMQB accepts four lines of BCD inputs data, generates their complements internally and decodes the data with seven AND/OR gates having open-collector outputs to drive indicator segments directly. The features of the 54LS47FMQB are: (1)open-collector outputs; (2)drive indicator segments directly; (3)casecadable zero-suppression capability; (4)lamp test input.

The following is about the absolute maximum ratings of 54LS47FMQB: (1)supply voltage: 7V; (2)input voltage: 7V; (3)operating free air temperature range: -55 to +125; (4)storage temperature range: -65 to +150.

The electrical characteristics of the 54LS47FMQB are: (1)input clamp voltage: -1.5V max at VCC=min, II=-18mA; (2)high level output voltage: 2.4V min at VCC=min, IOH=max, VIL=max; (3)low level output voltage: 0.4V max at VCC=min, IOH=max, VIL=max; (4)input current @ max input voltage: 100A max at VCC=max, VI=10V; (5)high level input current: 20A max at VCC=max, VI=2.7V; (6)low level input current: -0.4mA max at VCC=max, VI=0.4V; (7)short circuit output current: -0.3mA min and -2.0mA max; (8)supply current: 12mA max at VCC=max.
