The CDCM1804 has three control terminals, S0, S1, and S2, to select different output mode settings. The S[2:0] terminals are 3-level inputs and therefore allow up to 33 = 27 combinations. Additionally, an enable terminal (EN) is provided to disable or enable all outputs simultaneously. The EN terminal is a 3-level input as well and extends the number of settings to 2 x 27 = 54. See Table 1 for details. |
