SN74LVT18512DGG TI Universal Bus Transceiver | 18-Bit, 3.3V, 5V Tolerant

Product Overview

The SN74LVT18512DGG from Texas Instruments is a high-performance 18-bit universal bus transceiver designed for asynchronous communication between data buses. It operates with a 3.3V supply voltage while maintaining 5V tolerant I/Os, making it ideal for mixed-voltage systems. The device features two 18-bit input/output ports (A and B) with direction control (DIR) and output-enable (OE) inputs. It supports bidirectional data flow with a propagation delay of typically 3.5 ns, ensuring high-speed operation. The SN74LVT18512DGG is housed in a TSSOP package (56-pin) and is characterized for operation from -40°C to 85°C.
