Nexperia USA Inc. 74HC4017D,653

Overview

74HC4017D,653 from Nexperia is a CMOS Johnson decade counter IC with 10 decoded outputs (Q0–Q9), dual-edge-triggered clock inputs (CP0 and CP1), asynchronous master reset (MR), and carry output Q5-9. It operates from 2.0 V to 6.0 V, delivers propagation delays as low as 18 ns at 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). It is used in sequential timing control, LED chasers, and divide-by-N counters.

For engineers reviewing the 74HC4017D,653 datasheet, 74HC4017D,653 pinout, 74HC4017D,653 application, or 74HC4017D,653 equivalent, this device serves as a low-power, TTL-compatible (via 74HCT variant) decade counter for discrete logic sequencing where precise decoded state selection and cascading capability are required.

Technical Context

The 74HC4017D implements a 5-stage Johnson counter architecture that generates 10 unique decoded outputs via internal decoding logic. Its dual-clock interface allows flexible triggering: CP0 advances on LOW-to-HIGH while CP1 = LOW; CP1 advances on HIGH-to-LOW while CP0 = HIGH - enabling bidirectional clock domain interfacing.

It features automatic illegal-state recovery within ≤11 clocks, asynchronous MR reset (active HIGH), and Q5-9 carry output active LOW during states 5–9 - directly usable for cascading multiple devices without external logic. Input clamp diodes permit overvoltage-tolerant interfacing with current-limiting resistors.

FAQ

What is the difference between 74HC4017D and 74HCT4017D?

The 74HC4017D uses CMOS-level inputs (VIH ≥ 70% VCC), while the 74HCT4017D features TTL-compatible inputs (VIH ≥ 2.0 V at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 74LS logic without level shifters. Both share identical pinout, decoded outputs, and functional behavior.

Can 74HC4017D,653 drive LEDs directly?

Yes - each output can source or sink up to ±25 mA at VCC = 6.0 V, sufficient to drive standard 20 mA LEDs with appropriate current-limiting resistors. For higher-current or multiplexed loads, external transistors are recommended to maintain timing integrity and thermal safety.

How does the Q5-9 output enable cascading?

Q5-9 is LOW during count states 5 through 9 and HIGH otherwise. When wired to CP0 of a second 74HC4017D, it advances the slave counter once per 5-count block - enabling seamless 100-state sequencing (10 × 10) without external logic or microcontroller intervention.

Is automatic illegal-state recovery guaranteed under all conditions?

Yes - internal correction circuitry ensures return to a valid counting sequence within 11 clock cycles after any illegal state (e.g., caused by ESD, power glitch, or metastability), verified across −40 °C to +125 °C and full VCC range per Nexperia's product data sheet Rev. 8.
