Bare Die Product Detail: 54ALS51

Combination logic Gate:
The 54ALS51 is fabricated using using a 2µm 40V Bipolar process. The device consists of two independent gate combinations which perform the logic AND-OR-INVERT function and are structured as 2-wide 3-input gates and 2-wide 2-input gates.

The device directly replaces legacy Texas Instruments (TI) 54LS51, SN54LS51 and legacy SN54S51, 54S51 or 5451 produced by National Semiconductor (NSC), TI or Fairchild (FSC).

Features:
** END OF LIFE ** NOT RECOMMENDED FOR NEW DESIGN

High speed – 14ns (Max) propagation delay
Lower power consumption than all preceding bipolar logic technologies
Military temperature range for high reliability
