Working Principles

The SN74LVCH16952ADGGR is designed to facilitate data transfer between two independent buses operating at different voltage levels. It utilizes bidirectional voltage level shifting techniques to ensure seamless communication. The direction control input (DIR) determines the flow of data between the two ports (Port A and Port B). When DIR is high, data flows from Port A to Port B, and when DIR is low, data flows from Port B to Port A. The output enable inputs (OE1 and OE2) control the tri-state outputs, allowing multiple devices to share the same bus without interfering with each other.

Detailed Application Field Plans

The SN74LVCH16952ADGGR is commonly used in various applications where data transfer between circuits operating at different voltage levels is required. Some typical application fields include: - Mixed-voltage systems - Communication interfaces - Microcontroller interfacing - Data acquisition systems - Industrial automation - Consumer
