Dm74ls32m m14a 14lead small outline integrated circuit soic, jedec ms, 0. The description for each pin is given below.
The circuit working can be explained in few stages below: With that the drop across resistor R1 will be zero. This enables the use of current limiting resistors to interface inputs to voltages in excess of dataxheet. When both buttons are not pressed. Absolute maximum ratings note if militaryaerospace specified devices are required, please contact the national semiconductor sales officedistributors for availability and specifications.
For better understanding the internal working let us consider the simplified internal circuit of AND gate as shown below. The chip provides TTL outputs which are needed in some systems. These two inputs are connected to buttons to change the logic of inputs. Fairchild quad 2input nand gate,alldatasheet, datasheet, datasheet search site for electronic components and semiconductors, integrated circuits. The four AND gates in the chip mentioned earlier are dattasheet internally as shown in diagram below.

Download or read online fairchild semiconductor 74ls08 quad 2input and gates pdf jc. TL — Programmable Reference Voltage. There are four and gates in the chip and each gate have two inputs, hence the name quadruple 2 input and gate.
In this state the current flow through base of both transistors will be zero. There are four AND gates in the chip, we can use one or all gates simultaneously. The chip is basically used where AND logic operation is needed.
Fairchild manufactures this ic in a 14lead plastic dualinline package pdip, jedec ms, 0. If offer finest suppliers for 74ls08, 74ls08d, 74ls08db you can also download the datasheet for 74ls08, 74ls08d, 74ls08db.
After verifying the three states, you can tell that we have satisfied the above truth table. Both transistors will be ON and voltage across both of them will be zero.
When both buttons are pressed. Dm quad 2input and gates dm quad 2input and datasheet general description this device contains four independent gates each of which performs the logic and function.
