PCE85176AUG - NXP

PCE85176AUG 4 x 40 LCD segment driver

The PCE85176AUG is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD)1 with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 40 segments. The PCE85176AUG is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus..
