FEATURES:
IDT74FCT863A/B
DESCRIPTION:
• Equivalent to AMD's Am29861-64 bipolar registers in pinout/
function, speed, and output drive over full temperature and
voltage supply extremes
• IDT74FCT863A equivalent to FAST™ speed
• IDT74FCT863B 25% faster than FAST
• High-speed symmetrical bidirectional transceivers
• IOL = 48mA
• Clamp diodes on all inputs for ringing suppression
• CMOS power levels (1mW typ. static)
• TTL input and output level compatible
• CMOS output level compatible
• Substantially lower input current levels than AMD's bilopar
µA max.)
Am29800 series (5µ
• Available in SOIC package
The IDT74FCT800 series is built using an advanced dual metal CMOS
technology. The IDT74FCT863 9-bit transceivers have NAND-ed output
enables for maximum control flexibility.
All of the IDT74FCT800 high-performance interface family is 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 highimpedance state.

NOTES:
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. Output and I/O terminals only.

NOTES:
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.
5. These are maximum IOL values per output, for 10 outputs turned on simultaneously. Total maximum IOL (all outputs) is 480mA. Derate IOL for number of outputs exceeding 10
turned on simultaneously.
