... Display Overview The HCMS-39XX series is a family of LED displays driven by on-board CMOS ICs. The LEDs are configured as 5x7 font characters and are driven in groups of 4 characters per IC. Each IC consists of a 160-bit shift register (the Dot Register), two 7-bit Control Words, and refresh circuitry ...

... These bits must always be programmed to logic low. Cascaded ICs Figure 8 shows how two ICs are connected within an HCMS-39XX display. The first IC controls the four left-most characters and the second IC controls the four right- most characters. The Dot Registers are connected in series to form a 320-bit dot shift register ...

... The inputs to the ICs are protected against static discharge and input current latch up. However, for best results, standard CMOS handling precautions should be used. Before use, the HCMS-39XX should be stored in antistatic tubes or in conductive material. During assembly, a grounded conductive work area should be used and assembly personnel should wear conductive wrist straps ...
