Overview

FEATURES: • Equivalent to ALS speeds and output drive over full temperature 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.
