NAND GATE

NAND GATE

The 74LS00 is a 14 pin IC that houses a quad 2 input NAND gate.   This is a very useful logic gate as it can be used to construct other gates and circuits.

Having ordered some coloured header pins.  This is now nicely soldered up on to strip board.  I have only added enough pins for 2 of the 4 NAND gates, partly to avoid the board being cramped with pins.

NAND GATE TRUTH TABLE

Further details on the NAND gate can be found here,  this includes internal circuit diagram, truth table, and other details.

 

Update 28/11/2019 – I have now build a 2nd board up.   This went much quicker than the first time.
