HEF4017BT,652

Counter Dividers Overview

The HEF4017BT,652 is a 5-stage Johnson decade counter manufactured by Nexperia USA Inc. It 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). The device includes active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous master reset input (MR). It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS. The component utilizes Schmitt trigger action for clock inputs, providing tolerance to slow rise and fall times.

Counter Dividers Feature Summary

• Automatic counter correction circuitry ensures return to proper counting mode following any illegal code within 11 clock pulses.
• Schmitt trigger action on clock inputs provides high tolerance for slower signal rise and fall times.
• Fully static operation with standardized symmetrical output characteristics across specified voltage ratings.

Counter Dividers Applications

• Decade counter with decimal decoding
• Sequential controller
• Timer

Counter Dividers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range specifications. Confirm product status as production data sheet information before initiating design implementation. Ensure compatibility with system voltage levels and load capacitance requirements based on dynamic characteristic formulas provided in the datasheet.

Counter Dividers Selection Notes

Select this component for designs requiring a 5-stage Johnson counter with multiple decoded outputs. Verify that the application environment falls within the specified -40 °C to +125 °C operating temperature range. Consider the SO16 plastic small outline package dimensions for PCB layout constraints. Evaluate power dissipation calculations if driving significant capacitive loads at high frequencies.

Counter Dividers Part Context

This part belongs to the HEF4017B series, which is a 5-stage Johnson decade counter family produced by Nexperia. The series is designed for general-purpose digital logic applications requiring sequential counting and decoding functions. The HEF4017BT variant specifically denotes the surface-mount SO16 package configuration suitable for automated assembly processes.
