DESCRIPTION:
The FCT163244/A/C 16-bit buffer/line drivers are built
using advanced dual metal CMOS technology. These highspeed, 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/A/C 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/A/C can be used as buffers to connect
5V components to a 3.3V bus.
