Overview
The HEF4017BT-Q100J, produced by Nexperia USA Inc., is a 5-stage Johnson decade counter. This integrated circuit features ten spike-free decoded active HIGH outputs (Q0 to Q9) and an active LOW carry output from the most significant flip-flop (Q5-9). It also includes active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous master reset input (MR). The counter is designed for robust operation, with automatic counter code correction and high tolerance for slow clock rise and fall times due to Schmitt trigger action.

Q & A
- What is the HEF4017BT-Q100J?
The HEF4017BT-Q100J is a 5-stage Johnson decade counter with ten spike-free decoded active HIGH outputs and an active LOW carry output. - What is the power supply range for the HEF4017BT-Q100J?
The power supply range is from 3.0 V to 15.0 V. - What are the clock input conditions for advancing the counter?
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. - How does the master reset input work?
A HIGH on the MR input resets the counter to zero (Q0 = Q5-9 = HIGH; Q1 to Q9 = LOW) independent of the clock inputs. - What is the significance of Schmitt trigger action in the HEF4017BT-Q100J?
Schmitt trigger action makes the clock inputs highly tolerant of slower rise and fall times. - What are the ESD protection ratings for the HEF4017BT-Q100J?
The device exceeds 2000 V for HBM (ANSI/ESDA/JEDEC JS-001 class 2) and 1000 V for CDM (ANSI/ESDA/JEDEC JS-002 class C3). - What is the operating temperature range for the HEF4017BT-Q100J?
The operating temperature range is from -40 °C to +125 °C. - What package type is the HEF4017BT-Q100J available in?
The device is available in an SO16 (SOT109-1) package. - Does the HEF4017BT-Q100J have automatic counter code correction?
Yes, the counter has automatic counter code correction, returning to a proper counting mode within 11 clock pulses after any illegal code. - What are some typical applications for the HEF4017BT-Q100J?
