- Part of the IDT54AHCT521 comparator family.
- Part of the IDT54AHCT521 comparator family.
Features
:
- Equivalent to ALS speeds and output drive over full temperature and voltage supply extremes
- 9ns typical propagation delay
- IOl = 14m A over full military temperature range
- CMOS power levels (5Jl.W typo static)
- Both CMOS and TTL output patible
- Substantially lower input current levels than ALS (5Jl.A max.)
- 8-bit identity parator
- 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 parator built using advanced CEMOS", a dual metal CMOS technology. The device pares two words of up to eight bits each and provides a LOW output when the two words match bit for bit. The expansion input I A =8 also serves as an active LOW enable input.
