The 74FCT163244 16-bit high-speed, low-power buffer/line drivers offer bus/ backplane interface capability with improved packing density. The three-state controls operate these devices in a Quad-Nibble, Dual-Byte or single 16-bit word mode. The inputs can be driven from either 3.3V or 5V devices allowing the use of these devices as translators in a mixed 3.3V/5V supply system. Thus, the 74FCT163244 can be used as buffers to connect 5V components to a 3.3V bus. The 74FCT163244 operates at -40C to +85C
