seriously disabled Posted October 11, 2009 Share Posted October 11, 2009 What do these symbols mean in electronics? [math]V_{DDH}[/math] [math]V_{DDL}[/math] [math]V_{SSH}[/math] [math]V_{SSL}[/math] Link to comment Share on other sites More sharing options...
Klaynos Posted October 11, 2009 Share Posted October 11, 2009 Some context would be useful, it could be just about anything. Link to comment Share on other sites More sharing options...

Klaynos Posted October 11, 2009 Share Posted October 11, 2009 I've never seen them in a LC context and without knowing more couldn't even guess at what they mean. Link to comment Share on other sites More sharing options...
seriously disabled Posted October 11, 2009 Author Share Posted October 11, 2009 I think it means: VDDH = voltage drain drain high VDDL = voltage drain drain low VSSH = voltage source source high VSSL = voltage source source low Link to comment Share on other sites More sharing options...
SH3RL0CK Posted October 12, 2009 Share Posted October 12, 2009 Perhaps reading the manufacturers datasheet for the LCD driver would help? Really when you have an IC with perhaps dozens of connections to the circuit, these could mean anything. Link to comment Share on other sites More sharing options...
