摘要:
A complementary input circuit is used to transfer the state of an external input (ADR IN) to the internal signal lines (ADR, ADR) of an integrated circuit chip.
A nonlinear input circuit has an input terminal (ADR IN) for receiving the external input and provides an output to a first node (a) only when the external input exceeds a reference voltage (V R ) and a threshold voltage. It comprises further latch means having first and second output nodes (b. c) connected to the internal signal lines (ADR, ADR ) of the integrated circuit chip and having an input node common to said first node (a) for receiving the output of the nonlinear input circuit, said latch means comprising transistor devices (3, 4, 5. 6) which are partially cross-coupled.
