In addition to phase reversal of input signal, single npn transistor provides isolation between negative input pulse and core driver, which is Schmitt trigger having discrimimation level within 10% of -4.5 v including phase inverters. Signals below that level are disregarded. Signal range from 6 to 12 v will cause pulse output from Schmitt, with duration dependent on duration of input signal. When Schmitt trigger emits pulse, 1N704 driver supplies 30-ma current pulse, writing a ONE into ifs associated core.-R. Wasserman und W.
