j-Fet test ::




scs test (a variety modified from the 7-th ed. GE Transistor Manual 1964) ::

about :: the following is carried out on intent to find out the low-power-edge function of the scs / pulse-driven logic - - coz there're a lot of old discretes lying around nothing to do with - - in most cases the DTL is out performing such in a sense of power efficiency (but there are few exceptions and some conditional exceptions . . . most yet to be defined . . .)


(-a-) -- incomplete design of low power HOLD capable RAM/Counter . . .


(-b-) -- i guess the proper operational voltage levels' range selection allows the following to operate without pulse amp stages . . .



(-c-) -- ↓it↓ draws about 10mA per cascade/stage for about 400kHz CLK src. (& takes an additional circuitry to read the trigger OUTP levels . . . e.g. adding even more power use in real implementation . . . )
