COMMON CATHODE ROW

Notes:

1. Average power is based on 20 dots per character. Total package power dissipation should not exceed 1.5 W.

2. Do not exceed maximum average current per dot.

3. For the HDSP-L10X/M10X series displays, derate maximum average current above 35

°C at 0.31 mA/°C. For the HDSP-L20X/450X

series and HDSP-540X/510X series displays, derate maximum average current above 35

°C at 0.2 mA/°C. This derating is based on a

device mounted in a socket having a thermal resistance junction to ambient of 50

°C/W per package.
