Notes:
1. All voltages referenced to a VDD of 0 V.
2. V1 and V4 must satisfy the relationship VDD V1, V4 VSSH
3. Exceeding the absolute maximum ratings can cause permanent damage to the device. Functional operation under these conditions is not implied.
4. Moisture resistance of flat packages can be reduced by the soldering process. Care should be taken to avoid thermally stressing the package during board assembly.




Description

The SED1190 is a dot matrix LCD common (row) driver for driving high-capacity LCD panel at duty cycles higher than 1/64. The LSI uses two serially connected, 32-bit shift registers to hold the display data, and level shifter converts the TTL level 64-bit parallel data from the shift registers to levels suitable for use by the LCD drive circuitry. The SED1190 generates common drive signals using the voltages supplied to LCD drive voltages pins.

The SED1190 is used in conjunction with the SED1180 (64-bit row driver) to drive a large capacity dot matrix LCD panel.
