Description

The SN74LS47N is designed as low power schottky BCD to 7 segment decoder/ drivers consisting of NAND gates, input buffers and seven and-or-invert gates. It offers active low, high sink current outputs for driving indicators directly.

SN74LS47N has five features. (1)Lamp intensity modulation capability (BI/RBO). (2)Open collector outputs. (3)Lamp test provision. (4)Leading/ trailing zero suppression. (5)Input clamp diodes limit high-speed termination effects. Those are all the main features.

Some guaranteed operating ranges of SN74LS47N have been concluded into several points as follow. (1)Its supply voltage range would be min 4.75V and typ 5.0V and max 5.25V. (2)Its operating ambient temperature range would be min 0°C and typ 25°C and max 70°C. (3)Its output current high level would be max -50uA. (4)Its output current low level would be max 3.2mA. (5)Its off state output voltage would be max 15V. (6)Its on state output current would be max 24mA.

Also some DC characteristics of SN74LS47N are concluded as follow. (1)Its input high voltage would be min 2.0V with conditions of guaranteed input high voltage for all inputs. (2)Its input low voltage would be max 0.8V with conditions of guaranteed input low voltage for all inputs. (3)Its input clamp diode voltage would be typ -0.65V and max -1.5V with condition of Vcc=min, Iin=-18mA. (4)Its output high voltage would be min 2.4V and typ 4.2V with condition of Vcc=min and Ioh is max and input voltage is high level or low level per truth table. (5)Its output low voltage would be typ 0.25V and max 0.4V with condition of Iol=max. (6)Its input high current would be max 20uA with condition of Vcc=max and Vin=2.7V and would be max 0.1mA with conditions of Vcc=max, Vin=7.0V. (7)Its input low current would be max -0.4mA with condition of Vcc=max and input voltage is 0.4V. (8)Its power supply current would be max 13mA with condition of Vcc=max. (9)Its short circuit current would be min -0.3mA and max -2mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
