The µPD161644A is a TFT-LCD gate driver with power supply for TFT-LCD driver. Because this gate driver has a level shift circuit for logic input, it can output a high gate scanning voltage in response to a CMOS-level input. This ICs can generate the levels which TFT-LCD driver need, from 2.7 V.
The uPD161644A is a TFT‑LCD gate driver that provides 241 selectable outputs and includes an on‑chip regulator for source drivers. It accepts 2.7 V CMOS‑level inputs and can generate up to a 40 V breakdown voltage for high‑voltage gate scanning.
The document contains block diagrams, pin‑layout tables, boost‑voltage generation details, and handling precautions for CMOS devices. It also outlines ordering information and quality‑grade classifications for various application fields.
