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). • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4017 are high-speed Si-gate CMOS devices and are pin compatible with the “4017” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. When cascading counters, the Q5-9 output, which is LOW while the counter is in states 5, 6, 7, 8 and 9, can be used to drive the CP0 input of the next counter. A HIGH on MR resets the counter to zero (Q0 = Q5-9 = HIGH; Q1 to Q9 = LOW) independent of the clock inputs (CP0 and CP1). The 74HC/HCT4017 are 5-stage Johnson decade counters with 10 decoded active HIGH outputs (Q0 to Q9), an active LOW output from the most significant flip-flop (Q5-9), active HIGH and active LOW clock inputs (CP0 and Automatic code correction of the counter is provided by an internal circuit: following any illegal code the counter returns to a proper counting mode within 11 clock pulses.

December 1990 11 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). It is essential not to enable the counter on CP1 when CP0 is HIGH, or on CP0 when CP1 is LOW, as this would cause an extra count. Fig.10 Counter expansion Figure 11 shows an example of a divide-by 2 through divide-by 10 circuit using one “4017”. Since “4017” has an asynchronous reset, the output pulse widths are narrow (minimum expected pulse width is 6 ns). The output pulse widths can be enlarged by inserting a RC network at the MR input.
