The SN74ACT245DWRG4 is a high-speed, octal bus transceiver designed for bidirectional communication between data buses in asynchronous systems. It has separate enable inputs to control data flow direction. When enabled, it transfers data non-inverted from either the A to B ports or vice versa, depending on the state of the direction control input (DIR). This device features TTL-compatible logic levels and operates with supply voltages from 4.5V to 5.5V. Its DWRG4 package offers enhanced thermal performance and is suitable for high-density applications. The outputs are tri-stated when disabled, ensuring safe interface with multiple devices on a shared bus.
