Visão Geral
Description
The device features an OE (output enable) pin, allowing it to isolate buses when not in use, helping save power. It supports partial power-down mode, ensuring no back-drive current flows into the device when it is powered down. With high-speed operation and robust signal integrity, it's optimized for systems that demand quick data processing and reliable performance. Its small footprint, offered in a 10-pin UQFN package, makes it ideal for space-constrained applications in consumer electronics, computing, and communication devices. This transceiver provides designers with a flexible and efficient solution for managing multi-voltage compatibility challenges.
Equivalent
1. NXP 74AVC2T245 - Dual supply translating transceiver.
2. ON Semiconductor FXMA2102 - Dual supply voltage level translator.
3. Microchip Technology's MCPDCT2T245 - Dual supply bus transceiver.
Ensure that the chosen alternative meets your specific requirements such as voltage levels, data rates, and packaging. Always consult the datasheets for precise specifications and compatibility.
Features
1. Voltage Level Translation: Supports translation between 0.65 V to 3.6 V on both A and B ports, allowing for flexible interfacing between different voltage levels.
2. High-Speed Operation: Operates with data rates up to 420 Mbps, suitable for high-speed data transfer applications.

4. Direction Control: Includes a direction control (DIR) pin for controlled data flow, allowing for bidirectional communication.
5. Drive Capability: Capable of driving up to 20 pF loads.
6. Ioff Support: Offers partial power-down mode, preventing backflow current when the device is powered down.
7. Compact Package: Available in a small, space-saving package suitable for compact designs.
These features make the SN74AXC2T245RSWR ideal for applications needing efficient voltage translation with minimal power usage.
Pinout
Pin Count: 12 pins
Functions:
- Voltage Level Shifting: Designed to translate signal voltages between different voltage nodes, from 0.65V to 3.6V on both sides.
- Dual-bit Transceiver: It can transfer data in both directions between the A and B ports.
- Direction Control: The DIR pin determines the direction of data flow.
- Output Enable: The OE pin controls whether the transceiver is enabled or placed in a high-impedance state.
This device is highly useful in interfacing applications where different parts of a system operate at different voltage levels. Its small form factor and low power consumption make it suitable for portable and space-constrained applications.
