SN74ABT651NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT651NT is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art EPIC-II BiCMOS design to significantly reduce power dissipation while providing high-drive outputs of -32 mA IOH and 64 mA IOL. The device supports multiplexed real-time and stored data transmission between two buses, A and B. It operates within a supply voltage range of 4.5 V to 5.5 V and is characterized for operation from -40°C to 85°C.
