All PI74FCT2XXX devices have a built-in 25-ohm series resistor on all outputs to reduce noise because of reflections, thus eliminating the need for an external terminating resistor. The PI74FCT827/828T and the PI74FCT2827/2828T are 10-bit wide bus drivers providing high-performance bus interface buffering for wide address/data paths or buses carrying parity. The 10-bit buffers have NAND-ed output enables for maximum control flexibility. They are designed for high-capacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs. The PI74FCT827/2827T is a non-inverting of the PI74FCT828/2828T. Device models available upon request.
