HD61203

The HD61203 is a common signal driver for dot matric liquid crystal graphic display systems.HD61203 generates the timig signals(switch signal to convert LCD waveform to AC, frame synchronous signal) and supplied them to the column driver to control display.It provides 64 driver output lines and the impedance is low enough to drive a large and the impedance is low enough to drive a large screen.

Features of the HD61203 are:(1): power supply voltage(vcc) is -0.3 V to 7.0 v; (2): power supply voltage(Vee) is Vcc-19.0 V to Vcc+0.3 V; (3): terminal voltage(VT1) is -0.3 V to Vcc+0.3 V; (4): terminal voltage(VT2) is Vee-0.3 V to Vcc+0.3 V; (5): operating temperature(Topr) is -20 to 75; (6): storage temperature(Tstg) is -55 to +125.

The absolute maximum ratings of the HD61203 can be summarized as:(1)dot matrix liquid crystal graphic display common driver with low impedance; (2)low impedance:1.5kohms max; (3)internal liquid crystal display driver circuit:64 circuits; (4)internal dynamic display timing generator circuit ; (5)low power dissipation: during display: 5mW; (6)power supplies: Vcc:5 V with 10% more or less; (7)power supply voltage for liquid crystal display drive: 8 V to 17 V; (8)CMOS process.
