Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT163244 is a 16-bit buffer/line driver designed for
applications driving high capacitive loads and low impedance
backplanes. This high-speed, low power device offers bus/backplane
interface capability and a flow-through organization for ease of
board layout. This device is designed with three-state controls to
operate in a Quad-Nibble, Dual-Byte, or a single 16-bit word
mode.

Propagation Delays and Enable/Disable times should be degraded by 20%.
2. See test circuit and wave forms.
3. Minimum limits are guaranteed but not tested on Propagation Delays.
4. This parameter is guaranteed but not production tested.
5. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
