The IDT54/74FCT800 series is built using an advanced
dual metal CMOS technology.
The IDT54/74FCT860 series bus transceivers provide
high-performance bus interface buffering for wide
data/address paths or buses carrying parity. The
IDT54/74FCT863 9-bit transceivers 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 the high- im-
pedance state.
