IDT74AHCT521 - High Speed CMOS 8-Bit Identity Comparator

Download the IDT74AHCT521 datasheet PDF. This datasheet also covers the IDT54AHCT521 variant, as both devices belong to the same high speed cmos 8-bit identity comparator family and are provided as variant models within a single manufacturer datasheet.

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.

expansion inputI A =8 also serves as an active LOW enable input.

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.
