74LS08 – 74LS08 Quad 2-Input AND Gates (Open Collector)

Normally will take working days. These two inputs are connected to buttons to change the logic of inputs. Because output is nothing but voltage across resistor R1 it will be LOW. Raspberry Pi Media Kit.

When both buttons are not pressed. Martin French part St. For better if the internal working let us consider the simplified internal circuit of AND gate as shown below.

74LS08 – 74LS08 Quad 2-Input AND Gates (Open Collector)

The two inputs of AND gate are driven out from bases of the two transistors. The chip is basically used where AND logic operation is needed. HTML is not translated! The chip is used in systems where high speed AND operation is needed.


International Shipping We ship internationally, no matter where you are. In the circuit two transistors are connected in series to form a AND gate. When any one of the buttons is pressed.

A few mentioned below. With that the drop across resistor R1 will be zero. There are four AND gates in the chip, we can use oc or all gates simultaneously. At this time the total VCC appears across resistor R1. It is really popular and is available everywhere. The circuit working can be explained in few stages below: The chip provides TTL outputs which are needed 74ks08 some systems.


This LED is connected to detect the state of output.
