SED1180F

The SED1180F is a kind of LCD segment driver which is used in conjunction with the SED1190F (LCD common drivers). It can drive a large dot-matrix LCD display with a duty ratio of 1/64 or higher.

There are some features of SED1180F as follows: (1)display duty: 1/64 to 1/128; (2)64-bit high voltage resistant output, LCD driver (segment driver); (3)rightward shift suitable for a 1/64-duty panel; (4)power supply for the logic: 5 V±10%; (5)CMOS high-voltage-resistant process: 25 V (max); (6)4-bit bus data transfer; (7)80-pin QFP (plastic); (8)allows cascade-connection. Dasy-chain connection of enable pins can be used to minimize power consumption.

The following is about thw absolute maximum ratings of SED1180F: (1)supply voltage, VSS: -7.0 to 0.3 V; (2)supply voltage, VSSH: -28.0 to 0.3 V; (3)supply voltage, V2, V3: -28.0 to 0.3 V; (4)input voltage, VI: VSS-0.3 to 0.3 V; (5)operating temperature, Topr: -20 to 75; (6)storage temperature, Tstg: -65 to 150; (7)soldering temperature (10s), Tsol: 260.
