... Rev DISPLAY DRIVER WITH 18 DIGITS, 6 SYMBOLS AND CLOCK/TIMER General Description The AS2590 is an integrated CMOS device for driving a liquid crystal display intended for use in telephones. The 2-wire serial interface is compatible to the dialler AS2574B. The extreme low operating current allows the circuit to be operational also during on-hook which is necessary in order to the use of the clock function ...
