The 74HC Family use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits
in this example the Priamry power will be provided by the Arduino
Package Type : TO-220
0V to VCC input range
It can easily transfer data wirelessly
74HC47 ( BCD to 7-Segment Decoder) 74HC08 The 74HC Family use siliconIntroduction : 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
