DESCRIPTION:
The IDT54/74FCT800 series is built using an advanced
dual metal CMOS technology.
The IDT54/74FCT827A/B/C 10-bit bus drivers provide
high-performance bus interface buffering for wide data/ ad-
dress paths or buses carrying parity. The 10-bit buffers have
NAND-ed output enables for maximum control flexibility.
All of the IDT54/74FCT800 high-performance interface
family are designed for high-capacitance load drive capability,
while providing low-capacitance bus loading at both inputs
and outputs. All inputs have clamp diodes and all outputs are
designed for low-capacitance bus loading in high-impedance
state.
