LC7941ND

The LC7941ND is designed as one kind of segment driver LSIs for driving large, dot-matrix LCD displays. This device read 4-bit parallel or serial input, display data from a controller into an 80-bit latch, and then generate LCD drive signals corresponding to that data. And this device features mirror-image pin assignments, allowing them to be used together to increase component density. They are designed to be used with the common driver to drive large LCD panels.

Features of the LC7941ND are:(1)80 built-in LCD display drive circuits;(2)1/8 to 1/128 display duty cycle;(3)serial or 4-bit parallel data input;(4)chip disable for low power dissipation for large sized panels;(5)bias supply voltages can be supplied externally;(6)CMOS process;(7)100-pin flat plastic package.

The absolute maximum ratings of the LC7941ND can be summarized as:(1)logic supply voltage: -0.3 to +7.0 V;(2)LCD supply voltage: 0 to 22 V;(3)input voltage: -0.3 to VDD+0.3 V;(4)operating temperature range: -20 to +85 ;(5)storage temperature range: -40 to +125 .
