SN74ACT245PWR TI Bus Transceiver | 20-TSSOP | 8-Bit, Non-Inverting

Product Overview

The SN74ACT245PWR is an octal bus transceiver from Texas Instruments designed for asynchronous bidirectional communication between data buses. It features 8-bit non-inverting buffers with 3-state outputs, allowing for bidirectional data flow controlled by direction (DIR) and output enable (OE) inputs. The device operates with a supply voltage range of 4.5V to 5.5V, making it suitable for 5V systems. Housed in a 20-pin TSSOP package, it offers a compact solution for bus interface applications.
