Logic Block Diagram
Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the Company’s advanced CMOS technology,
achieving industry leading speed grades.
The PI74FCT162244MT is a non-inverting 16-bit buffer/line
driver designed specifically for applications driving heavy
loads—ideally for DRAM modules/arrays and heavy load bus
applications. This very high-speed, high-drive, low noise buffer
driver device meets the JEDEC specification for DRAM DIMM
module buffer drivers.
The PI74FCT162244MT offers a flow-through organization for
ease of board layout. This part is plug-in compatible with the
74ABT16244/162244 and excels in applications where much
higher speed and lower power dissipation are required.
The output drivers of the PI74FCT162244MT have the features
of a balanced drive and controlled edge rate, resulting in
minimal undershoot/ringback and ground bounce. This
eliminates the need for external series termination resistors.
