SN74ABT646ADBR TI Bus Transceiver | 24-SSOP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ABT646ADBR from Texas Instruments is a high-performance 8-bit bus transceiver with non-inverting 3-state outputs, designed for bidirectional asynchronous communication between data buses. Housed in a compact 24-SSOP package, this device operates from a 4.5V to 5.5V supply and features typical propagation delays of 4.6 ns, making it suitable for high-speed data transfer in digital systems. It incorporates two 8-bit D-type latches with separate latch-enable (LEAB and LEBA) and output-enable (OEAB and OEBA) inputs for flexible control.
