SN74LVTH2245DW TI Bus Transceiver | 20-SOIC | 3.3V, 8-Bit, Non-Inverting

Product Overview

The SN74LVTH2245DW from Texas Instruments is a high-performance, 8-bit bus transceiver designed for 3.3-V VCC operation with 5-V tolerant I/Os. It features non-inverting 3-state outputs and is ideal for bidirectional asynchronous communication between data buses. The device is part of the LVT family, offering low-voltage operation with high drive capability (up to 64 mA sink/32 mA source). Packaged in a 20-pin SOIC (DW), it is suitable for space-constrained applications requiring robust signal integrity.
