DESCRIPTION OF FUNCTION AND OPERATION 1. Entry of serial data © Serial data used to control the IC is input through three terminals, CLK, DATA and STB. ® During the rise of a clock pulse, data is fed to the shift register in the IC in order from the LSB. ® Upon the reception of all data, the strobe signal (STB) is made “H”. @ After the situation of @, the data stored in the shift register is transferred to the latch in the block selected by the group code, whereby the IC is controlled. @ The three terminals, CLK, DATA and STB, contains Schmitt trigger circuits to prevent the data errors by noise, etc. O Serial data group and group code @ The IC has control divided into four groups so that they may be controlled independent of one another. Each group is identified by a two-bit group code attached at the data end.
