SN74ALS245A-1N TI Bus Transceiver | 20-PDIP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ALS245A-1N is a high-performance octal bus transceiver from Texas Instruments, 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 bus-oriented systems. Housed in a 20-pin PDIP package, this device operates from a single 5V supply and is characterized for operation from 0°C to 70°C. The SN74ALS245A-1N is ideal for applications requiring high drive capability and low power consumption, such as memory interfaces, microprocessor systems, and industrial control.
