74HC47 or 74LS47 IC BCD to seven segment decoder driver

7447 or 74LS47 decodes BCD
into 7 Segments, which means it accepts a binary coded decimal or BCD
Values as input and decoded into a pattern that drives a 7-segment for
displaying digits 0 to 9, so its name is BCD to 7 segment driver or
decoder. Its input is 4 lines BCD data and generates complements as
output. The generation of complement data of BCD is internally so no
coding or programming is required to generate it.

Specification

• Large Voltage range
• Has open collector output which directly drives indicator
• Has a wide range of operating conditions
• No need for external resistors because of internal pull-ups
• No high-speed termination because of the input clamp diode
• 4 the number of input lines and 7 output lines
