DESCRIPTION:
FEATURES:
The FCT827T is built using an advanced dual metal CMOS
technology.
• Common features:
– Low input and output leakage ≤1µA (max.)
– CMOS power levels
– True TTL input and output compatibility
– VOH = 3.3V (typ.)
The FCT827T/FCT2827T 10-bit bus drivers provide high-
performance bus interface buffering for wide data/address
pathsorbusescarryingparity. The10-bit buffershaveNAND-
ed output enables for maximum control flexibility.
All of the FCT827T high-performance interface family are
designed for high-capacitance load drive capability, while
providing low-capacitance bus loading at both inputs and
outputs.Allinputshaveclampdiodestogroundandalloutputs
are designed for low-capacitance bus loading in high-imped-
ance state.
The FCT2827T has balanced output drive with current
limiting resistors. This offers low ground bounce, minimal
undershoot and controlled output fall times-reducing the need
for external series terminating resistors. FCT2827T parts are
plug-in replacements for FCT827T parts.
