SN74ACT245NSR TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ACT245NSR 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 package (NSR suffix), this device operates over a wide voltage range of 4.5V to 5.5V, making it suitable for 5V logic environments. The ACT245 offers improved speed and drive capability compared to standard 245 transceivers, with typical propagation delays of 7.5ns and output drive of ±24mA at 5V.
