The FCT16240T 16-bit buffer/line driver is built using advanced dual metal
CMOS technology. These high-speed, low-power devices offer bus/backplane
interface capability with improved packing density. The flow-through organization of signal pins simplifies layout. The three-state controls are designed to
operate these devices in a Quad-Nibble, Dual-Byte or single 16-bit word mode.
All inputs are designed with hysteresis for improved noise margin.
The FCT16240T is ideally suited for driving high capacitance loads and lowimpedance backplanes. The output buffers are designed with power off disable
capability to allow "live insertion" of boards when used as backplane drivers.
