74HC47 ( BCD to 7-Segment Decoder) 085 Filling machines

Filling machines

Supply Voltage Range: 2V to 6V

three select inputs(S0 to S2) and an enable input (E)

You can connect this board directly to 5V systems (5V power in to VCC) and the SDA and SCL pins will be at 5V levels

IA=B and IA<B)to the least significant position must be connected as follows: IA<B = IA>B = LOWand IA=B = HIGH

74HC47 ( BCD to 7-Segment Decoder) 085 Filling machinesIntroduction : 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
