SN74HC640PWR TI Bus Transceiver | 20-TSSOP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74HC640PWR from Texas Instruments is a high-performance octal bus transceiver designed for asynchronous two-way communication between data buses. It features 8-bit non-inverting buffers with 3-state outputs, enabling bidirectional data flow with direction control via the DIR input. The device operates over a wide supply voltage range of 2V to 6V, making it suitable for interfacing with various logic families. Housed in a compact 20-pin TSSOP package, it is ideal for space-constrained applications requiring high-speed data transfer and low power consumption.
