The SN74LVT245DWR is a high-performance, octal bus transceiver from Texas Instruments, designed with the purpose of providing bidirectional communication between two data buses. The device is a part of the LVT family, which stands for Low-Voltage BiCMOS Technology, and it operates with a 3.3V power supply, making it suitable for interfacing with low-voltage logic without the need for external level shifters.

Key Features

• Octal Bidirectional Transceiver with 3-state outputs
• Supports mixed-mode signal operation (5V input and output voltages with 3.3V Vcc)
• Wide operating voltage range (2.7V to 3.6V)
• High-drive outputs (-32mA Io)
• Control inputs VIH/VIL levels are referenced to VCC voltage
• Low power consumption
• High-impedance state during power up and power down
• Latch-up performance exceeds 500mA per JESD 17

Product Applications

The SN74LVT245DWR is designed for asynchronous communication between data buses, making it an ideal choice for a wide range of applications, including:

• Memory interface buses
• Data interchange systems
• Signal buffering
• Input/Output (I/O) port expansion
• Backplane driving

Package and Quality

This device comes in a wide-body SOIC package (DWR suffix), which is a 20-pin surface-mount package, providing a compact footprint for space-constrained applications.
