The SN74LVT245BPWR is a Texas Instruments 8-bit bidirectional bus transceiver in a 20-pin TSSOP package, supplied on tape and reel. It operates from a 2.7V to 3.6V supply with a 3.3V nominal rail and delivers a 2.3ns propagation delay. Output drive is 64mA low-level and 32mA high-level, giving it the current capability needed to drive a loaded backplane. The SN74LVT245BPWR is rated for -40°C to 85°C.

An octal bus transceiver buffers eight signals in either direction under a single direction-control pin, isolating a driver from a heavily loaded bus and restoring clean edges. The SN74LVT245BPWR is used for data bus buffering between processors, memory and peripherals, backplane and connector driving, and interfacing a low-drive controller to long or capacitive traces. Its 64mA sink capability is well beyond ordinary logic families, which is what makes it a backplane part rather than a board-local buffer. Buyers are typically digital board designers in communications, industrial and computing equipment, and contract manufacturers stocking standard 3.3V logic.
