SN74LVCR2245ADBQR

The SN74LVCR2245ADBQR is a high-speed, low-voltage CMOS (Complementary Metal-Oxide-Semiconductor) bus transceiver designed by Texas Instruments. It is part of the LVCR (Low-Voltage CMOS) family and is specifically engineered for use in high-performance applications that require reliable data transmission.

Key Features:

1. Bus Transceiver Functionality: The device operates as a dual 8-bit transceiver, allowing for bidirectional data flow between two buses. This makes it suitable for applications where data needs to be sent and received simultaneously.

2. Voltage Levels: The SN74LVCR2245ADBQR is designed to operate with a supply voltage range of 2.7V to 3.6V, making it compatible with low-voltage systems. It is particularly well-suited for interfacing with 3.3V logic levels.

3. High-Speed Operation: The device supports high-speed data rates, with a maximum propagation delay of around 5 ns at 3.3V, enabling fast communication in digital circuits.

4. Low Power Consumption: The LVCR series is known for its low power consumption, which is critical in battery-operated devices and energy-efficient applications.

5. Input/Output Configuration: The transceiver features a tri-state output, allowing for easy connection to multiple devices on a bus without signal contention. The I/O pins can be configured for either input or output, providing flexibility in circuit design.

6. Control Logic: The device includes control pins (DIR, OE) that manage the direction of data flow and enable/disable the outputs, respectively. This allows for precise control over the data transmission process.

7. Temperature Range: The SN74LVCR2245ADBQR is rated for operation over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications.

8. Package Type: The device is available in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, which provides a compact footprint for space-constrained designs.

9. Applications: Common applications include data communication between microcontrollers, interfacing with memory devices, and connecting to peripheral devices in consumer electronics, automotive systems, and industrial automation.

Electrical Characteristics:

• Input High Voltage (VIH): Typically around 2.0V for a 3.3V supply.
• Input Low Voltage (VIL): Typically around 0.8V for a 3.3V supply.
• Output High Voltage (VOH): Typically close to VCC (supply voltage).
• Output Low Voltage (VOL): Typically close to ground.

Summary:

The SN74LVCR2245ADBQR is a versatile and efficient bus transceiver that meets the demands of modern digital communication systems. Its combination of low voltage operation, high-speed performance, and low power consumption makes it an ideal choice for a wide range of applications in various electronic devices.
