Logic circuit receiving signal deflection or deviation - has compensator keeping constant propagation delay time including extended temp. range (NL 5.12.77)

摘要

Logic circuit has an input terminal (16) for signal deflection or deviation reception. A differential transistor circuit (10) responds to the input signal deflection etc., and causes a corresponding output signal change in response to internal signal generation in a specified propagation delay time. The transistor circuit (10) has energy supply terminals (VCC, VEE) to which a variable or unestablished voltage is applied. They are connected to a compensator (14), also connected to the input terminal (16), in order to keep constant the propagation delay time over the ambient temp. range.
