Working Principles

The 74AVCH4T245PW,112 is a bidirectional level shifter and translator IC. It operates by monitoring the voltage level at the OE# pin. When the OE# pin is low, the IC is enabled, and it translates signals between the A and B ports bidirectionally. The direction of translation depends on the voltage levels of the input signals. The IC supports voltage translation between different logic families, allowing seamless integration of components operating at different voltage levels.

Detailed Application Field Plans

The 74AVCH4T245PW,112 IC finds applications in various electronic systems where voltage level translation is required. Some common application fields include: 1. Microcontroller interfacing with different peripheral devices operating at different voltage levels. 2. Communication interfaces between different logic families, such as CMOS and TTL. 3. Level shifting in battery-powered portable devices to interface with sensors or displays operating at different voltages. 4. Signal translation in mixed-voltage systems, such as automotive electronics or industrial control systems.

Detailed and Complete Alternative Models

1. SN74LVC1T45: Unidirectional voltage level translator with a single channel.
