IDT54/74FCT841A/B/C
FEATURES:
• Equivalent to AMD’s Am29841-46 bipolar registers in
pinout/function, speed and output drive over full tem-
perature and voltage supply extremes
• IDT54/74FCT841A equivalent to FAST™ speed
• IDT54/74FCT841B 25% faster than FAST
• IDT54/74FCT841C 40% faster than FAST
• Buffered common latch enable, clear and preset inputs
• 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 IDT54/74FCT840 series bus interface latches are
designed to eliminate the extra packages required to buffer
existing latches and provide extra data width for wider address/
data paths or buses carrying parity. The IDT54/74FCT841 is
a buffered, 10-bit wide version of the popular ‘373 function.
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-imped-
ance state.
