Nexperia USA Inc. 74HC4040PW,112

Overview

74HC4040PW,112 from Nexperia is a 12-stage asynchronous binary ripple counter IC with CMOS logic, operating from 2.0 V to 6.0 V supply. It advances on the HIGH-to-LOW clock edge (CP), features an active-HIGH asynchronous master reset (MR), and delivers twelve independent Q0–Q11 outputs. Used in frequency division and timing control circuits where low-power, rail-to-rail output swing and wide temperature operation (−40 °C to +125 °C) are required.

For engineers reviewing the 74HC4040PW,112 datasheet, 74HC4040PW,112 pinout, 74HC4040PW,112 application, or 74HC4040PW,112 equivalent, this device serves as a foundational timing and counting element in embedded control, industrial sequencing, and digital signal conditioning-where precise cascaded division ratios (up to 2¹² = 4096) and robust noise immunity are essential.

Technical Context

This device implements a chain of twelve static toggle flip-flops, each triggered by the falling edge of its predecessor's output-resulting in inherent ripple propagation delay between stages. Its asynchronous MR input forces all outputs LOW independently of CP state, enabling immediate system synchronization without clock dependency.

Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The TSSOP16 package (SOT403-1) supports high-density PCB layouts while maintaining thermal performance up to +125 °C ambient, with total power dissipation derated linearly at 8.5 mW/K above 91 °C.

FAQ

What is the maximum clock frequency supported by the 74HC4040PW,112?

The 74HC4040PW,112 supports a maximum clock frequency of 98 MHz at VCC = 4.5 V with CL = 15 pF load. At VCC = 6.0 V, fmax drops to 98 MHz (typical) but derates to 24 MHz under worst-case conditions (−40 °C to +125 °C, CL = 50 pF). This limit applies to the CP input; individual output frequencies decrease by powers of two down the chain.

Can the 74HC4040PW,112 be used with a 3.3 V supply?

Yes-the 74HC4040PW,112 operates reliably from 2.0 V to 6.0 V, including 3.3 V nominal supplies. At VCC = 3.3 V, VIH is guaranteed ≥2.1 V and VOL ≤0.26 V at 4 mA sink, ensuring clean interfacing with 3.3 V microcontrollers and FPGAs without level translation.

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

The MR input is fully asynchronous: asserting MR HIGH immediately forces all Q0–Q11 outputs LOW, regardless of CP state or timing. No clock edge is required, and the reset takes effect within tPHL(MR→Qn) - typically 22 ns at VCC = 4.5 V - making it suitable for emergency system halt or power-on initialization.

Does the 74HC4040PW,112 have built-in ESD protection?

Yes-it features HBM ESD protection exceeding 2000 V and CDM protection exceeding 1000 V per JEDEC JS-001/JS-002 standards. These ratings are validated per manufacturer testing and reflect robustness against handling and board-level electrostatic discharge, reducing need for external protection in most industrial layouts.
