2 Pieces SN 74LS147 LINE ENCODER IC 10-T0-4

Description

What it is

The SN 74LS147 is an integrated circuit that functions as a binary-to-BCD (Binary Coded Decimal) signal converter. This component is designed to convert decimal numbers from 0 to 9 into binary code, making it useful for counting and numerical display applications.

Features

• Converts binary signals to BCD code
• Compatible with Arduino and other microcontrollers
• Used for the realization of digital counters

What it is for

The SN 74LS147 is ideal for makers developing counter or numeric display projects. It can be used to create a simple digital counter that displays the count from 0 to 999999 on a seven-segment display. It is compatible with Arduino and other microcontrollers for managing binary signals.
