概要

Description

The 74LVT245MTC is a high-performance, low-voltage bidirectional transceiver designed for asynchronous two-way data communication between buses. It is part of the 74LVT series, which are logic devices utilizing advanced BiCMOS technology. The device features eight non-inverting buffers that can be directed to take data from either the A or B side, controlled by a direction control input (DIR) and an output enable input (OE).
Key features include a wide supply voltage range, typically operating from 2.7V to 3.6V, and the capability to interface with 5V TTL logic levels, making it versatile for various applications. The 74LVT245MTC is known for its high-speed operation, low power consumption, and the ability to sink/source a substantial amount of current, allowing it to drive heavy loads.
The device is typically housed in a 20-pin TSSOP (Thin Shrink Small Outline Package), which aids in reducing board space. It is commonly used in applications requiring data buffering, bus interfacing, and signal integrity maintenance across digital systems.
