HD66137T
High-Voltage Durable 240-Channel Common Driver
for Dot-Matrix STN LCD
ADE-207-291(Z)
Rev. 2
Aug. 03, 1999
Description
The HD 66137T is a 240-channel common driver which drives a dot matrix STN LCD panel. By changing
the mode, this can be applied to 240- and 200- and 160- channel output. Through the use of a 43-V high-
voltage CMOS process technology, a high-voltage drive of +21.5 V and –21.5 V, centering on VM is
possible. –21.5V generated from +21.5 V with built-in switching circuit and external capacity. Low logic-
drive voltage (3 V) is used. This device is used together with the segment driver HD66130, HD66134ST or
HD66136.
Features
• Display duty: Up to 1/240
• LCD drive voltage: 43 V max
• Built-in switching circuit (to generate –21.5 V)
• Number of LCD drive circuit: 240
• Operating voltage: 2.5 to 5.5 V
• Intermediate voltage I/F
• Built-in alternating signal generation circuit Pin programmable
• Output mode change: 240-output mode
200-output mode
160-output mode
• Built-in display-off function
• Flex TCP
