SN74LVCR2245ADGVR - Texas Instruments

The SN74LVCR2245ADGVR from Texas Instruments is a high-performance, octal bus transceiver featuring non-inverting 3-state bus compatible outputs. Designed with the cutting-edge biCMOS technology, this device is optimized for low-voltage operation, ranging from 2.7V to 3.6V, making it suitable for interfacing with 3.3V logic in mixed 3.3V/5V systems.

This transceiver allows for bidirectional communication between two buses by transmitting data from A to B or B to A, depending on the logic level at the direction control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

The SN74LVCR2245ADGVR is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions. It comes in a compact 20-pin TSSOP (DGVR) package, which is ideal for space-constrained applications.

Key Features:

• Operational Voltage Range: 2.7V to 3.6V
• BiCMOS Technology with Low Static Power Consumption
• High-Drive Outputs (-24mA IOH, 24mA IOL)
• Control Inputs VIH/VIL Levels Are Referenced to VCC Voltage
• Bus Hold on Data Inputs Eliminates the Need for External Pull-up/Pull-down Resistors
• Latch-Up Performance Exceeds 250mA Per JESD 17
• ESD Protection Exceeds JESD 22

The device's high-drive outputs and robust latch-up performance make it an excellent choice for driving heavy loads with minimal propagation delay. Additionally, the SN74LVCR2245ADGVR includes bus hold on data inputs, which helps to prevent floating inputs and reduces the need for external components.

Whether you're designing data communication systems, memory interface circuits, or need reliable level shifting in your mixed-voltage designs, the SN74LVCR2245ADGVR from Texas Instruments is a versatile and dependable solution that delivers both performance and integration ease.
