Nexperia USA Inc. 74HC4024PW,118

Overview

74HC4024PW,118 from Nexperia is a 7-stage binary ripple counter IC with asynchronous master reset (MR), clock input (CP) triggered on HIGH-to-LOW transition, and seven buffered Q0–Q6 outputs. It operates from 2.0 V to 6.0 V, delivers ≤35 ns propagation delay at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). Used in frequency division and time-delay circuits where low-power CMOS logic timing is required.

For engineers reviewing the 74HC4024PW,118 datasheet, 74HC4024PW,118 pinout, 74HC4024PW,118 application, or 74HC4024PW,118 equivalent, key selection criteria include edge-triggered ripple counting behavior, Schmitt-trigger clock input tolerance, MR active-HIGH asynchronous clear timing, and SO14 package compatibility with legacy 74HC logic layouts.

Technical Context

This device implements a cascaded chain of seven static toggle flip-flops, advancing state only on the falling edge of CP. Each stage drives the next via direct Q-to-CP connection, resulting in inherent ripple propagation-Q0 toggles first, then Q1, up to Q6-with cumulative delay per stage.

The Schmitt-trigger input on CP enables robust operation with slow-rising or noisy clock signals, while internal clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. MR forces all outputs LOW independently of CP state, enabling deterministic initialization.

FAQ

What is the maximum operating frequency of the 74HC4024PW,118?

The maximum clock frequency is 98 MHz at VCC = 6.0 V and CL = 50 pF, measured at the CP input. However, due to ripple architecture, the effective system-level maximum frequency for synchronized use of Q6 is limited by cumulative propagation delay - approximately 24 MHz at VCC = 6.0 V over the full −40 °C to +125 °C range.

Can the 74HC4024PW,118 be used with a 3.3 V supply?

Yes - the device is fully specified from 2.0 V to 6.0 V. At VCC = 3.3 V, VIH is guaranteed ≥ 2.31 V and VIL ≤ 1.09 V, ensuring reliable interfacing with standard 3.3 V CMOS outputs. Propagation delay increases to ~45 ns (CP to Q0) and fmax drops to ~45 MHz under typical conditions.

Is the master reset (MR) input synchronous or asynchronous?

MR is asynchronous and active HIGH. A HIGH applied to MR immediately clears all internal flip-flops and forces Q0–Q6 LOW within tPHL (≤43 ns at VCC = 6.0 V, −40 °C to +85 °C), regardless of CP state or timing - no clock edge is required for reset assertion or release.

Why does the 74HC4024PW,118 have three no-connect (n.c.) pins?

Pins 8, 10, and 13 are internally unconnected and reserved for package mechanical integrity and future product variants. They must remain unconnected in PCB layout - no pull-up, pull-down, or routing is permitted, as capacitive loading or unintended coupling could degrade noise immunity or timing margins.
