74LS08 IC is a member of 74XXYY IC series. There are four AND gates in the chip and each gate have two inputs, hence the name QUADRUPLE 2- INPUT AND GATE. The gates in the chip are designed by SCHOTTKY TRANSISTORS for high speed logic operations.
74LS02 is a LOGIC GATE IC and member of 74XXYY IC series which are logic gates. There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE. The gates in the chip are designed by low power SCHOTTKY TRANSISTORS.
74LS04 is a member of 74XXYY IC series. The 74-series are digital logic integrated circuits.
74LS04 IC has six NOT gates. These NOT gates perform Inverting function.
74LS00 is a member of 74XXYY IC series. The 74xxyy ICs are logic gates of digital electronics. 74LS00 IC has four NAND gates. Also each gate has two inputs.
74HC14 is a member of 74XXXX series ICs, which consists of LOGIC GATES. 74HC14 IC has six NOT gates with SCHMITT TRIGGER. Hence name HEX INVERTING SCHMITT TRIGGER.
