Product Specification?

• IC number: 7447
• Applicable for: BCD to 7 Segment converters and displays number from 0 to 9
• Maximum Voltage supply: 5.25V
• Minimum Voltage supply: 4.75V
• Package contains: checked and unused 1 piece of 7447 Ic
• Type: DIP
• Pins: 16

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

<li>Has open collector output which directly drives the 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
