SN74HC640DW TI Bus Transceiver | 20-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74HC640DW from Texas Instruments is a high-performance octal bus transceiver designed for asynchronous two-way communication between data buses. It features non-inverting outputs with 3-state capability, allowing for bidirectional data flow controlled by direction (DIR) and output enable (OE) inputs. The device operates over a wide voltage range of 2V to 6V, making it suitable for interfacing with various logic families. Housed in a 20-pin SOIC package, it offers a compact solution for bus-oriented systems.
