计数器、寄存器、译码器、显示器等功能部件在数字式仪器、仪表等装置得到了广泛应用。在实际使用中一般采用分立的数字集成块和显示器,为了方便整机系统设计、提高整个系统可靠性、使仪器仪表小型化,将CMOS逻辑电路和发光二极管(LED)数码显示管组合为一体。LCL002,LCL102两种CMOS——LED组合器件正是基于这个思想产生的, Counters, registers, decoders, monitors and other features in the digital instruments, instruments and other devices have been widely used. In the actual use of discrete digital integrated block and display generally, in order to facilitate the whole system design, improve the reliability of the entire system, the instrument miniaturization, the CMOS logic circuit and light-emitting diode (LED) digital display tube as a whole. LCL002, LCL102 two CMOS - LED combination device is based on this idea is produced,
