Product Overview: 74LVT245D from NXP
The 74LVT245D is a high-performance, low-voltage, bi-directional transceiver designed by NXP Semiconductors. This integrated circuit is part of NXP's LVT (Low-Voltage Technology) family, which is known for its ability to operate at lower voltages while providing excellent speed and output drive capabilities. The 74LVT245D is specifically tailored for high-speed bidirectional communication between data buses.
Key Features
- Bi-Directional Interface: With its bi-directional data interface, the 74LVT245D can transfer data in both directions, from A to B or B to A, making it highly versatile for data bus management.
- Low-Voltage Operation: The device operates at a nominal supply voltage of 3.3V, which can range from 2.7V to 3.6V, providing compatibility with lower voltage systems and contributing to power conservation.
- 5V Tolerant I/O Ports: Despite its low-voltage design, the I/O ports are 5V tolerant, allowing for interfacing with 5V logic levels without the risk of damage.
- High Drive Capability: The 74LVT245D boasts a strong drive capability, with 64mA on the A ports and 32mA on the B ports, ensuring reliable signal transmission even in heavy load conditions.
- Bus-Hold Function: The device features a bus-hold function, which maintains the last active state of the bus lines when they are left floating, reducing the need for external pull-up or pull-down resistors.
