DESCRIPTION:

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.
