Vintage Signetics IC Chip RARE UNKNOWN UNTIL NOW! NE557 - 555 556 567 Collection
I was a Signetics Field Sales Engineer back in the early 1970s covering the Minneapolis/St.Paul account base. But just before that I was working for Magic Dot. A start-up company. Designing and building thick film touch capacitance switches. These devices required a highly sensitive input and an output capable of driving various electro-mechanical devices and logic circuits. The first device was a skin resistance/breath touch switch and our company had been working with Hans Camenzind at Interdesign to design the IC chip. Hans chose to use the 555 timer and change the top metal layer to accommodate our needs. I used this modified chip in its die form to build our touch capacitance switches, that had to be protected from static discharges. In the small thick-film fab area we had. Later I met with Hans in the Bay area as we were developing ... morea keyboard version wi th BCD encoding that we subsequently had made in the CDC fab plant in Bloomington. MN. I still have my test samples of those chips too! I parted ways with Magic Dot to join the Signetics sales team and we were constantly receiving samples for our customers to evaluate. I received five samples of a device printed NE557V that I'm offering for sale individually in collections of other timer devices from that family. These Collections includes one of each- NE555V very early date code. NE555V with a later date code. NE556A. NE557V. And a NE567 which isn't a member of the timer family. The 555 timer chip is said to be the longest produced chip in the history of integrated circuits and is still in mass production today in its variants and technologies. What makes these collections unique is the inclusion of an unknown member of this series! After many years I contacted Hans about this device and asked him what he thought it was. I have the email where he said that he wasn't aware of a device in the timer series that had that numbering and suggested it was probably a misprinted NE567V that is a phase locked loop tone detector that I believe he worked on
Versatile, Universal 555 TIMER IC Theory, App & Project Book for Experimenters
The 555 Timer Applications Sourcebook. With Experiments 0912 The 555 Timer Applications Sourcebook With Experiments by Howard M. Berlin 1st Edition 1988; but still a remarkably thorough and very practical library addition. Experimenters and projecteers take note: This is the perfect book for beginner and intermediate level hobbyists. Projects include measurement& control. Game, photography, environmental, telephone, automotive and home applications. And all circuits are based on the inexpensive NE555(CA555, LM555 etc. timer integrated circuit. Even old-timers who have not been properly introduced to the'555 will enjoy exploring it's endless possibilities. This is your complete one-stop reference for the NE555[and the companion'dual 555' known as the'556' Signetics introduced the NE555 in the early'70s. It took ... morea few years before it's enormous potential was realized. Today it is still the most popular IC with HAMs and experimenters. Soon. Many other manufacturers began producing their own compatible versions from CA555 to XR555, et. al. The author, Howard Berlin, recognized a need for a specialty book to thoroughly teach the theory in the language of the average technician along with his collection of diverse application ideas for this revolutionary part. First published in 1976, this rare publication, is a real treasure. This is a 1st edition copy. 158 pp. This book explains the theory. All the different modes of operation, provides tons of projects with circuit descriptions and includes a section on experiments to help you develop your own designs. There is probably no better book dedicated to the the'555 timer. The most versatile and popular IC in the known Universe- and perhaps, even beyond. This book can make you the'555 timer expert among your nerd friends. Someone predicted a'555 based circuit will eventually resolve the problems with cold fusion(just kidding) 10 Chapters plus an Appendix with References and Index. Condition of Book Good. Some cover wear. Crea
