SN74LS245NSR TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74LS245NSR is a high-performance octal bus transceiver from Texas Instruments (TI), designed for bidirectional asynchronous communication between data buses. It features 8-bit non-inverting buffers with 3-state outputs, enabling efficient data flow control in digital systems. Housed in a 20-pin SOP (Small Outline Package) with a 1.27mm pitch, this device operates over a wide supply voltage range of 4.75V to 5.25V, making it suitable for TTL logic levels. The SN74LS245NSR is ideal for applications requiring high-speed data transfer, such as memory interfacing, microprocessor systems, and industrial control.
