PCF8577 Datasheet (Philips) - LCD direct/duplex driver

PCF8577, LCD direct/duplex driver

The PCF8577 is a single chip, silicon gate CMOS circuit.

It is designed to drive liquid crystal displays with up to 32 segments directly, or 64 segments in a duplex manner.

The two-line 12 Cbus interface substantially reduces wiring overheads in remote display applications.

Bus traffic is minimized
