FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The FCT163244 16-bit buffer/line drivers are built using advanced dual
metal CMOS technology. These high-speed, low-power devices offer bus/
backplane interface capability with improved packing density. These
devices have a flow-through organization for simplifying board layout. The
three-state controls 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 inputs of the FCT163244 can be driven from either 3.3V or 5V
devices. This feature allows the use of these devices as translators in a
mixed 3.3V/5V supply system. Thus, the FCT163244 can be used as
buffers to connect 5V components to a 3.3V bus.
