RENESAS 74FCT16952ATPAG

The FCT16952T 16-bit register transceiver is manufactured using advanced dual-metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit D-type register transceivers with separate input and output controls that independently control data flow in either direction. For example, the A-to-B enable (xCEAB) must be low to input data from the A port. xCLKAB controls the clock function. When xCLKAB transitions from low to high, the existing data on the A port is clocked into the register. xOEAB performs the output enable function on the B port. Data flow from the B port to the A port operates similarly, but requires the xCEBA, xCLKBA, and xOEBA inputs. Full 16-bit operation is achieved by connecting the control pins of the individual transceivers together.

The FCT16952T is ideal for driving high-capacitance loads and low-impedance backplanes. The output buffers feature power-off disable functionality, allowing boards to be "hot-inserted" when used as backplane drivers.
