SN74LS641-1N TI Octal Bus Transceiver | 20-PDIP | Non-Inverting, 3-State

Product Overview

The SN74LS641-1N is a high-performance octal bus transceiver from Texas Instruments (TI), designed for bidirectional asynchronous communication between data buses. It features non-inverting outputs with 3-state capability, allowing multiple outputs to share a common bus. The device is housed in a 20-pin PDIP package and operates over a wide temperature range. With its low-power Schottky (LS) technology, it offers a balance of speed and power consumption, making it suitable for a variety of digital systems.
