74S134 12 Input NAND Gate (3-State)

PINOUT for the 74S134| 12 Input NAND

Useful for alarm systems, logic designs, and more. See datasheet below. Pin 15 allows enabling/disabling of all inputs. Diagrams show 3D connection in Ultiboard and 2D schematic in Multisim. 

The 74LS133 is a 13 input NAND gate TTL. When all inputs are High the output is Low. When one or more inputs is Low the output is High.

In this short blog I will express my ideal uses for the74LS134. When I first came across this archaic IC the one thing that popped in mine was a labyrinth with many doors that can be monitored with sensor signals reporting to the TTL and a simple output triggered when a door is opened or closed.


I am sure there are tons of creative ways to use this it. 


How would you implement this TTL?
