The GMX2X88C series are single color displays with the exception of GMC2688C, a bicolor of red/green displays. All displays have gray face and white dot color. Other face or dot colors are available with minimum requirement. The X in GMX denotes row anode or row cathode. 2.3 (58.4mm) character height Low power requirement High contrast & brightness Wide viewing angle 130 8x8 array with X-Y select = Compatible with USASCII and EBCDIC codes @ X-Y stackable = Choice of two matrix orientation anode or cathode column @ Easy mounting on PCB = Categorized for luminous intensity Single color displays have the choice of 3 bright color yellow/orange/green = Multicolor color displays are applicable to 3 bright colorgreens, orange (HER) and yellow (green and HER mixed)2.3"8x8 OPTOELECTRONICS DOT MATRIX DISPLAYS YELLOW HER GREEN UNITS Power dissipation per dot/color ............... 60 70 75 mw Peak forward current per dot/color (duty cycle 1/10, 10KHz) ..............2... 80 100 100 mA Continuous |; per dot/color .................05 20 25 25 mA Reverse voltage V, per dot/color .............. 5 5 5 Vv Operating and storage temperature range 2.0... cee een nee ene e beeen ene ne nene 25C to +B5C Soldering time at 260C (1/16 inch below seating plane) ....... 00k e tenet b renee tees 3 sec [ MODEL NUMBER PART NO.
