STMicroelectronics HCF4017M013TR

Overview

HCF4017M013TR from STMicroelectronics is a B-series CMOS 5-stage Johnson decade counter with 10 decoded outputs, operating up to 10 MHz (typ.) at VDD = 10 V, featuring Schmitt-trigger clock input, ripple-carry output, and full static operation across 3–20 V supply. It serves as a synchronous decimal counter in timing, sequencing, and LED driver circuits.

For engineers reviewing the HCF4017M013TR datasheet, HCF4017M013TR pinout, HCF4017M013TR application, or HCF4017M013TR equivalent, key selection criteria include decoded output timing accuracy, clock inhibit control latency, carry-out duty cycle integrity, and VDD-dependent noise margin compliance per JEDEC JESD13B.

Technical Context

The HCF4017M013TR implements a Johnson counter architecture with anti-lock gating to ensure deterministic state progression and spike-free decoded outputs. Each of the ten outputs (Q0–Q9) asserts high for exactly one full clock cycle, while CARRY-OUT toggles every 10 clocks-enabling cascaded multi-decade counting without external synchronization logic.

Its Schmitt-trigger clock input accepts unlimited rise/fall times, eliminating need for external pulse shaping; clock inhibit and asynchronous reset inputs provide precise start/stop and zero-reset control independent of clock edge timing. All DC and dynamic parameters are fully characterized from −55°C to +125°C.

FAQ

Is HCF4017M013TR pin-compatible with CD4017BE?

Yes, HCF4017M013TR uses the same SO-16 footprint and identical pin mapping as CD4017BE, including VDD (pin 16), VSS (pin 8), CLOCK (pin 14), RESET (pin 15), CLOCK INHIBIT (pin 13), CARRY-OUT (pin 12), and decoded outputs Q0–Q9 on pins 1, 2, 3, 4, 5, 6, 7, 9, 10, 11. No PCB redesign is needed for drop-in replacement.

What is the maximum recommended load capacitance for decoded outputs?

The HCF4017M013TR is characterized with CL = 50 pF in dynamic testing. While it can drive higher capacitance, sustained loading above 100 pF may degrade propagation delay consistency and increase transition time beyond 200 ns (max) at VDD = 5 V. For >100 pF loads, buffer stages are advised.

Does HCF4017M013TR support 3.3 V operation?

No - the minimum recommended VDD is 3 V, but DC and AC specifications are not guaranteed below 5 V. At 3.3 V, output drive strength drops significantly (IOH/IOL < ±0.2 mA), noise margin falls below 1 V, and maximum clock frequency degrades to <1 MHz. Use only within 5–20 V range for full spec compliance.

Can CARRY-OUT be used as a clock source for another HCF4017M013TR?

Yes - CARRY-OUT delivers a clean 10× divided square wave with 50% duty cycle and propagation delay matched to decoded outputs. When directly connected to the CLOCK input of a second device, it enables synchronous multi-decade counting with no additional logic, provided both devices share the same VDD and ground reference.
