FEATURES:

DESCRIPTION:

The IDT54/74FCT800 series is built using an advanced

dual metal CMOS technology.

• Equivalent to AMD’s Am29841-46 bipolar registers in

pinout/function, speed and output drive over full tem-

perature and voltage supply extremes

The IDT54/74FCT840 series bus interface latches are

designed to eliminate the extra packages required to buffer

existinglatchesandprovideextradatawidthforwider 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

familyaredesignedforhigh-capacitanceloaddrivecapability,

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.

• 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
