74HC47 ( BCD to 7-Segment Decoder) 085 USB power supplyIntroduction : 74HC47 is a BCD to 7 segment latch decoder driver with four address inputs (A, B, C, D), a latch enable input (LE), a ripple blanking input (BI), a lamp test input (LT), and seven segment outputs (a to g). When LE is LOW, the state of the segment outputs (a to g) is determined by the data on A to D. When LE goes HIGH, the last data present on A to D are stored in the latches and the segment outputs remain stable. When LT is LOW, all the
