Question-> 1.what is the internal structure(complete circuit diagram) of AND gate ic
7408?
2.Is it made using FET's(field effect transistors) or using simple transistors.
7408 IC is a QUAD 2-Input AND GATES and contains four independent gates, each of which performs the AND logic function. Fairchild manufactures this IC in a 14-Lead Plastic Double-In-Line Package (PDIP), JEDEC MS-001, 0.300 "wide.
The 4081 is a member of the 4000 series CMOS range, and contains four independent CMOS Y ports, each with two inputs. The pin diagram, given on the right, is the standard two-input logic gate IC design:
• Pin 7 is the negative supply
• Pin 14 is the positive supply
• Pins 1 and 2, 5 and 6, 8 and 9, 12 and 13 are door inputs
• The pins 3, 4, 10, 11 are door outputs.
