Nexperia USA Inc. 74HC4024PW-Q100J

Overview

74HC4024PW-Q100 from Nexperia is a 7-stage binary ripple counter IC with asynchronous master reset (MR), Schmitt-trigger clock input (CP), and seven buffered outputs (Q0–Q6). It advances on HIGH-to-LOW CP transitions, operates from 2.0 V to 6.0 V, delivers ≤30 ns propagation delay at VCC = 6.0 V, and is qualified to AEC-Q100 Grade 1 for automotive timing and frequency division.

For engineers reviewing the 74HC4024PW-Q100 datasheet, 74HC4024PW-Q100 pinout, 74HC4024PW-Q100 application, or 74HC4024PW-Q100 equivalent, this page provides verified functional identity, SO14/TSSOP14 package mapping, automotive-grade thermal specs (−40 °C to +125 °C), propagation delay and power dissipation data, and validated alternatives for frequency division and time-delay circuits.

Technical Context

This device implements a cascaded chain of seven static toggle flip-flops, where each stage divides its input frequency by two-yielding Q6 as the ÷128 output. The Schmitt-trigger CP input ensures robust operation with slow-rising/falling clock edges, and the overriding MR input forces all outputs LOW asynchronously, independent of CP state.

Inputs include integrated clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. The CMOS architecture delivers low static current (≤160 μA at +125 °C) and supports dynamic operation up to 24 MHz at full temperature range, with propagation delay (Qn→Qn+1) as low as 20 ns at VCC = 6.0 V and Tamb = +125 °C.

FAQ

What is the maximum clock frequency supported by 74HC4024PW-Q100 at +125 °C?

The maximum guaranteed clock frequency is 24 MHz at Tamb = +125 °C and VCC = 6.0 V, as specified in Table 7 (Dynamic characteristics). This value reflects worst-case propagation delay (Qn→Qn+1 ≤20 ns) across the full 7-stage chain under high-temperature stress, ensuring reliable divide-by-128 operation in under-hood environments.

Can the MR (master reset) pin be driven by an open-drain microcontroller GPIO?

Yes - the MR pin has CMOS-compatible input thresholds and draws ≤1.0 μA leakage current at VCC = 6.0 V. When pulled HIGH via a 10 kΩ resistor to VCC, an open-drain MCU GPIO can safely assert MR by pulling it LOW. No external level shifter is needed for 3.3 V or 5 V controllers.

Does 74HC4024PW-Q100 support mixed-voltage interfacing (e.g., 3.3 V inputs driving a 5 V VCC system)?

Yes - the input clamp diodes allow safe interface to voltages up to VCC + 0.5 V. With VCC = 5.0 V, 3.3 V logic signals applied to CP or MR are within safe limits. External 1 kΩ series resistors limit clamp current to <1 mA, satisfying the ±20 mA absolute maximum rating without additional protection circuitry.

How does the Schmitt-trigger input improve noise immunity on the CP line?

The Schmitt-trigger input provides hysteresis (typ. 0.3 × VCC) between rising and falling thresholds, rejecting noise spikes <1.5 V peak-to-peak at VCC = 5.0 V. This prevents false clocking from EMI-induced ringing on long PCB traces - a critical advantage in automotive harness environments where clock signals often traverse noisy power domains.
