SN74HCT646DWR TI Bus Transceiver | 24-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74HCT646DWR from Texas Instruments is a high-speed, 8-bit bus transceiver with non-inverting 3-state outputs. It is designed for asynchronous communication between data buses, featuring dual supply voltage compatibility (5V) and TTL-level inputs. The device is housed in a 24-pin SOIC package, making it suitable for space-constrained applications. It offers bidirectional data flow with direction control (DIR) and output enable (OE) pins, ensuring efficient bus management in digital systems.
