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/ address 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.

1. This parameter is measured at characterization but not tested.
1.Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. No terminal voltage may exceed VCC by +0.5V unless otherwise noted.
2.Input and VCC terminals only.
3.Outputs and I/O terminals only.

1.For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2.Typical values are at VCC = 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.
