ADSY8401

LCD Level Shifters with VCOM, NRS Buffers, and High Voltage Edge Detector ADSY8401 FEATURES Complete suite of level shifters Eight inverting and three complementary level shifters for LCD timing High voltage edge detector Integrated low offset buffer for VCOM drives high capacitive loads MUXed input, low offset buffer for 2-level precharge drives high capacitive loads High current buffer for precharge provides high current drive into large capacitive loads Low power dissipation: 576 mW Available in 48-lead 7 mm × 7 mm LFCSP E-pad DI1 DI2 DI3 DI4 DI5 DI6 DI7 DI8 DI9 DI10 DI11 FUNCTIONAL BLOCK DIAGRAM DVCC AVCCL AVCC ADSY8401 8 8 DO1 DO2 DO3 DO4 DO5 DO6 DO7 DO8 DO9T DO10T DO11T DO9C DO10C DO11C 3 3 3 R PRODUCT DESCRIPTION The ADSY8401 provides fast, 3 V to 15 V level shifters for LCD panel timing signals. An integrated low offset analog buffer is capable of driving the high capacitive loads. A 2:1 MUX input, low offset buffer simplifies application of 2-level precharge signals. A high current buffer provides high slew rates for large capacitive loads. The ADSY8401 is fabricated on ADI’s fast, 26 V XFHV process, providing fast input logic, high voltage level shifters, and precision drive amplifiers on the same chip. The ADSY8401 dissipates 576 mW nominal static power. The ADSY8401 is offered in a 48-lead 7 mm × 7 mm LFCSP www.DataSheet4U.com E-pad package and operates over the commercial temperature DTCTI S DTCTO +1 AMPI AMPO SEL MUXA MUXB +1 MUXO +1 BFRI GSW DGND AG...
