Philips Semiconductors Product specification Johnson decade counter with 10 decoded outputs 74HC/HCT4017 CP1) and an overriding asynchronous master reset input (MR). FEATURES • Output capability: standard The counter is advanced by either a LOW-to-HIGH transition at CP0 while CP1 is LOW or a HIGH-to-LOW transition at CP1 while CP0 is HIGH (see also function table).

Output capability: standard ICC category: MSI Note to HCT types The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.

Philips Semiconductors Product specification Johnson decade counter with 10 decoded outputs 74HC/HCT4017 APPLICATION INFORMATION Some applications for the “4017” are: • Decade counter with decimal decoding • 1 out of n decoding counter (when cascaded) • Sequential controller • Timer Figure 10 shows a technique for extending the number of decoded output states for the “4017”. Decoded outputs are sequential within each stage and from stage to stage, with no dead time (except propagation delay).
