Description

The STV7733 device is a low-power, controller/driver IC for dot-matrix displays. Data is encoded on two bits to select one of four possible output states: high level, medium level, ground or high impedance (Hi-Z).

Features

■ High-voltage, row/column driver IC

■ 320, tri-level (high-voltage, medium voltage and ground) power outputs:

– capable of operating at 90V, absolute max.

– capable of sinking or sourcing 2mA

– Hi-Z

■ Logic supply range: 2.5V to 3.3V

■ Slim shape die for COG, COF and TCP solutions

■ Interface:

– four dual (2-bit) input serial buses: DBA[1:2], DBB[1:2], DBC[1:2] and DBD[1:2] operating at shift clock frequency of 10MHz, max.

– three control inputs: shift clock direction (DIR), chip select (/CS) and data latch (/DL)

– two “all output” stage control inputs: AOC1 and AOC2

■ Power supplies:

– high-voltage for power outputs: 90V, max.

– logic supply suitable for battery powered applications: 2.5V, min.
