The 74FCT16952T 16-bit high-speed, low-power registered transceiver is organized as two independent 8-bit D-type registered transceivers with separate input and output control for independent control of data flow in either direction. Full 16-bit operation is achieved by tying the control pins of the independent transceivers together. The output buffers are designed with power off disable capability allowing "live insertion" of boards when used as backplane drivers. The 74FCT16952T operates at -40C to +85C
