Working Principles

The SN74ALVCH16409DGGR is a bidirectional logic level shifter that allows for data transfer between two voltage domains. It utilizes a combination of MOSFETs and control circuitry to ensure proper voltage translation. The OE1 and OE2 pins control the direction of data flow, while the A1-A16 and B1-B16 pins serve as the data inputs/outputs.

When OE1 is low and OE2 is high, data can be transferred from the A-side to the B-side. Conversely, when OE1 is high and OE2 is low, data can be transferred from the B-side to the A-side. The voltage levels on the A-side and B-side can differ within the specified range, allowing for seamless communication between devices operating at different voltage levels.

Detailed Application Field Plans

The SN74ALVCH16409DGGR is commonly used in various applications where data transfer between different voltage domains is required. Some specific application fields include:

1. Microcontroller interfacing with peripherals operating at different voltage levels
2. Communication interfaces between different logic families (e.g., TTL and CMOS)
