IDT54/74FCT863A/B
FEATURES:
• Equivalent to AMD’s Am29861-64 bipolar registers in
pinout/function, speed and output drive over full tempera-
ture and voltage supply extremes
• IDT54/74FCT861A/863A equivalent to FAST™ speed
• IDT54/74FCT861B/863B 25% faster than FAST
• High-speed symmetrical bidirectional transceivers
• IOL = 48mA (commercial) and 32mA (military)
• 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
bipolar Am29800 Series (5µA max.)
• Product available in Radiation Tolerant and Radiation
Enhanced versions
• Military product compliant to MIL-STD-883, Class B
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.

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.
3. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT +IINPUTS + IDYNAMIC
IC = ICC + ∆ICCDHNT + ICCD(fCP/2 + fiNi)
ICC = Quiescent Current
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
