Description: 7447 SN74HC47N 74HC47 74LS47 Decoder IC Dual In Package DIP 16 Pin IC

The 74LS47 accepts four lines of BCD (8421) input data, generates their complements internally and decodes the data with seven AND/OR gates having open-collector outputs to drive indicator segments directly. Each segment output is guaranteed to sink 24 mA in the ON (LOW) state and withstand 15V in the OFF (HIGH) state with a maximum leakage current of 250 mA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression functions.

Features:

• Open-collector outputs
• Drive indicator segments directly
• Cascadable zero-suppression capability
• Lamp test input
• Supply Voltage(Maximum):7V
• Supply Voltage(Recommended):5.25V
• Operating Free air temperature range:0ºC to 70ºC
