Product Overview: 74LVT245BPW from NXP

The 74LVT245BPW is a high-performance, low-voltage, bi-directional transceiver from NXP Semiconductors, designed for asynchronous communication between data buses. This integrated circuit is part of the LVT family, which is known for its low-voltage operation and tolerance to higher input voltages, making it ideal for interfacing between 3.3V and 5V systems.

Key Features

• Bi-Directional Interface: The 74LVT245BPW can transfer data in both directions, allowing for versatile communication between devices.
• Low-Voltage Operation: It operates at a nominal supply voltage of 3.3V, which is beneficial for power-sensitive applications.
• 5V Tolerant Inputs: Inputs can tolerate up to 5V, ensuring compatibility with a variety of logic levels and reducing the need for level shifters.
• High Drive Capability: The device can drive up to 64mA at the output, providing strong signal integrity even in heavy load conditions.
• Bus Hold Data Inputs: The bus hold feature on the data inputs eliminates the need for external pull-up or pull-down resistors, simplifying design and saving board space.
• Power-Off Disable: Outputs enter a high-impedance state when the power is off, preventing damaging backflow current.
• ESD Protection: Enhanced Electrostatic Discharge (ESD) protection shields the device from static damage during handling and operation.

Applications

The 74LVT245BPW is suitable for a wide range of applications, including:

• Interfacing between different logic levels in mixed 3.3V/5V systems.
• Communication buses in personal computers, servers, and networking equipment.
• Signal buffering and driving in backplane environments.
• Industrial control systems and data acquisition systems.

Package and Quality

The device is provided in a TSSOP-20 (Thin Shrink Small Outline Package) which is ideal for space-constrained applications. NXP's commitment to quality ensures that the 74LVT245BPW meets stringent industry standards for performance and reliability.
