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- im­pedance state.

2. Typical values are at V

CC = 5.0V, +25°C ambient and maximum loading.

3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.

4. This parameter is guaranteed but not tested.

5. These are maximum I

OL values per output, for 10 outputs turned on simultaneously. Total maximum IOL (all outputs) is 480mA for commercial and 320mA

for military. Derate I

OL for number of outputs exceeding 10 turned on simultaneously.
