SN74ABT2245DBR TI Bus Transceiver | 20-SSOP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ABT2245DBR is an 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, making it ideal for driving bus lines or buffering memory address registers. The device operates with a wide supply voltage range of 4.5V to 5.5V and offers high drive capability of ±32mA at the A port and ±64mA at the B port. Housed in a compact 20-SSOP package, it is suitable for space-constrained applications.
