IDT74AHCT521

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.
