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.
