Overview
Semiconductor ML9472 Static,1/2Duty 60 Output LCD Driver FEDL9472-02 Issue Date: Feb.
1, 2008 GENERAL DESCRIPTION The ML9472 is a LCD driver which can directly drive up to 60 segments in the static display mode and up to 120 segments in the 1/2 duty dynamic display mode.
FEATURES • O perating range Supply voltage : 3.
0 to 5.
5 V Operating temperature range : 40 to  105C • S egment output Static display mode : Up to 60 segments can be displayed.
1/2 duty : Up to 120 segments can be displayed.
• Simple interface with microcomputer • Built-in common signal generator • One-to-one correspondence between input data and output data When input data is at “H” level : Display goes on.
When input data is at “L” level : Display goes off.
• Test pin for all-on (SEG_TEST) and all-off (BLANK) • Can be cascade-connected • Can be synchronized with the external common signal • Applicable as an output expander • P ackage 80-pin plastic TQFP (TQFP80-P-1212-0.
