Fast CMOS 16-Bit Octal Buffer/Line Drivers
Product Description
Pericom Semiconductor's PI74FCT series of logic circuits are produced in the Company's advanced 0.6/0.8 micron CMOS technology, achieving industry leading speed grades. The PI74FCT16541T, PI74FCT162541T, and PI74FCT162H541T 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. They are designed with three-state controls to operate in a DualByte, or a single 16-bit word mode. The PI74FCT16541T output buffers are designed with a PowerOff disable allowing "live insertion" of boards when used as backplane drivers. The PI74FCT162541T has ±24 mA 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. The PI74FCT162H541T has "Bus Hold" which retains the input's last state whenever the input goes to high-impedance preventing "floating" inputs and eliminating the need for pull-up/down resistors.
