No Preview Available !

FEATURES:
• Equivalent to ALS speeds and output drive over full tempera-
ture and voltage supply extremes
• 9ns typical propagation delay
• IOl = 14mA over full military temperature range
• CMOS power levels (5Jl.W typo static)
• Both CMOS and TTL output compatible
• Substantially lower input current levels than ALS (5Jl.A max.)
• 8-bit identity comparator
• 100% product assurance screening to MIL-STD-883, Class B
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDT54174AHCT521 is an 8-bit identity comparator built
using advanced CEMOS", a dual metal CMOS technology. The
device compares two words of up to eight bits each and provides
a LOW output when the two words match bit for bit. The
expansion inputI A =8 also serves as an active LOW enable input.
