HEF4017B datasheet


Description :

The HEF4017B is a 5-stage Johnson decade counter with ten spike-free decoded active HIGH outputs (Q0 to Q9), an active LOW carry output from the most significant flip-flop (Q5-9), active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous masterreset input (MR).

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 Table 3).

Automatic counter code correction is providedby an internal circuit: following any illegal code the counter returns to a proper counting mode within 11 clock pulses.

Schmitt trigger action makes the clock inputs highly tolerant of slower rise and fall times.
It operates over a recommended VDDpower supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.

Features :

1. Automatic counter correction

2. Tolerant of slow clock rise and fall times

3. Fully static operation

4. 5 V, 10 V, and 15 V parametric ratings

5. Standardized symmetrical output characteristics
