STV7733 is a high-voltage, row/column driver IC with 320 tri-level (high-voltage, medium voltage and ground) power outputs. It can operate at 90V and supports logic supply range of 2.5V to 3.3V. It is suitable for COG, COF and TCP solutions.
The STV7733 is a high-voltage, row/column driver IC designed for dot-matrix displays. It features 320 tri-level power outputs capable of operating at up to 90V, allowing for high, medium, and ground voltage states or high impedance. The device supports a logic supply range of 2.5V to 3.3V and utilizes a slim shape die suitable for COG, COF, and TCP solutions.
The IC communicates with a host controller through an 8-bit parallel interface organized as four 2 x 80-bit shift registers operating at a maximum clock frequency of 10MHz. It includes control inputs for shift clock direction, chip select, data latch, and two 'all output' stage controls to manage simultaneous output configurations.
