Integrated interface circuitry for use in analog-digital circuits has data input provided before each of two separate, clock-controlled signal paths leading to corresponding outputs

摘要

The circuitry includes at least one cell block (1) and two separate, clock-controlled signal paths comprised of a utilizable data path and a test signal path. A data input (DI) is provided before the utilizable data path that leads to a data output (DO). A test data input (TDI) is provided before the test signal path that leads to a test data output (TDO).
