SN74AS245NS TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74AS245NS 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 digital systems. Housed in a 20-pin SOIC (SO-20) package, this device operates over a wide supply voltage range of 4.5V to 5.5V, making it suitable for 5V logic environments. With typical propagation delays of 6ns and high drive capability (±24mA output current), the SN74AS245NS is ideal for bus-oriented applications requiring high speed and noise immunity.
