Rare 1960s 1.6" Silicon Wafer - Mullard FCH211 NAND/NOR Sextuple Inverter - 39mm

About this Artwork: Logic chips were the first computer chips. The Mullard FCH211 logic chip was produced in the mid-1960s. The FCH211 was a NAND/NOR Sextuple Inverter Gate. The name is a mouthful, and it was a very advanced and flexible chip, providing three logic functions for 6 inputs and outputs. There are about 480 DTL Mullard FCH211 logic chips on this silicon wafer. The artwork on the front shows individual chips on the wafer. The FCH211 had 6 transistors, 15 diodes, and 6 resistors on each chip.The logic diagram to the right (on back of artwork) shows the circuit for the FCH211 logic chip. It is interesting to compare this logic diagram with the actual physical chip implementation on the front of the artwork. The input and output connections are identified on both the physical chip and the logic diagram.Unless you are versed on chip design, you might not be able to recognize the diodes, transistors, and resistors in the FCH211 chip image on the front of the artwork.
