PI74FCT162244T  
Fast CMOS 16-Bit Buffer/Line Drivers  
Description  
Features  
PericomSemiconductor’sPI74FCT16244TandPI74FCT162244T  
are non-inverting 16-bit buffer/line drivers designed for  
applications driving high capacitance loads and low impedance  
backplanes. These high-speed, low power devices offer bus/  
backplane interface capability and a flow-through organization  
for ease of board layout. These devices are designed with three-  
state controls to operate in a Quad-Nibble, Dual-Byte, or a single  
16-bitwordmode.

The PI74FCT16244T output buffers are designed with a Power-  
Off disable allowing “live insertion” of boards when used as  
backplane drivers.  
Power off disable outputs permit "live insertion"

The PI74FCT162244T has ±24mA balanced output drivers. It is  
designed with current limiting resistors at its outputs to control  
the output edge rate resulting in lower ground bounce and  
undershoot. This eliminates the need for external terminating  
resistors for most interface applications.
