SN74LVCR2245ADWR - Texas Instruments

The SN74LVCR2245ADWR from Texas Instruments is a versatile octal bus transceiver designed with two separate supply rails. This integrated circuit is part of the LVCR family, which is characterized by its low-voltage operation and robust performance. The device is particularly suitable for interfacing between different voltage domains within a system, making it an ideal choice for multi-voltage designs.

Key Features:

• Dual Supply Rails: The SN74LVCR2245ADWR operates with a 2.7V to 3.6V Vcc supply on the bus side and a 2.7V to 5.5V Vcc supply on the port side, allowing for flexible interfacing between different logic levels.
• Bi-Directional Data Flow: This transceiver allows for bidirectional data communication, with the direction controlled by the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device's outputs.
• High Drive Capability: The device can drive up 24 mA at the outputs, ensuring strong signal transmission over longer distances or through capacitive loads.
• Bus Hold on Data Inputs: The SN74LVCR2245ADWR comes with a bus hold feature that retains the last active state of the inputs, eliminating the need for external pull-up or pull-down resistors.
• Flow-Through Architecture: The pinout supports easy PCB layout with straightforward flow-through logic signal routing, minimizing signal crosstalk and reducing the need for additional vias.

Applications:

The SN74LVCR2245ADWR is a versatile component that can be used in a variety of applications. It is particularly useful in:

• Multivoltage digital systems
• Signal gating
• Data bus driving and switching
• Level translation for mixed-mode signal operation
• Communication systems
• Computing peripherals

Package and Quality:

Housed in a 20-pin SOIC package with a wide-body (DW) format, the SN74LVCR2245ADWR is designed for surface mount technology (SMT) and is compatible with standard soldering processes. Texas Instruments ensures high-quality and reliability for its components, and this product is no exception, meeting strict industry standards for performance.
