Part Number : HD74LS08P, HD74LS08
Function : Quadruple 2-input Positive AND Gates
Package : DIP 14 Pin type
Manufactures : Hitachi Semiconductor
These devices contain four independent 2-input AND gates. The 74LS series of integrated circuits are CMOS based logic ICs. The HD74LS08P quad 2 input and gates contains four independent gates each of which performs the logic AND function. 74ls08 quad 2 input and gate IC can be soldered directly to the circuit board or can be mounted on a 14 pin IC base. The 74ls08 quad 2 input and gates circuit is designed such that the AND operation of the input pins 1 &2 , 4&5, 9&10, 12,13 are produced on the pin 3 , 6, 8 & 11 respectively. Operating supply voltages to the IC can vary between 4.75V to 5V and to a maximum of 5.25V and the input logic levels to the device in ‘0’(LOW) state is max. 0.8V and for ‘1’(HIGH) state is min 2V.
