Product details
Overview
74HC4040PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 12-stage binary ripple counter with asynchronous master reset (MR), clock input (CP) triggering on HIGH-to-LOW transitions, and twelve buffered Q0–Q11 outputs. It operates from 2.0 V to 6.0 V across –40 °C to +125 °C and delivers 98 MHz maximum clock frequency at VCC = 6.0 V with CL = 50 pF - used in automotive timing control and frequency division circuits.
For engineers reviewing the 74HC4040PW-Q100 datasheet, 74HC4040PW-Q100 pinout, 74HC4040PW-Q100 application, or 74HC4040PW-Q100 equivalent, this page provides verified functional identity, automotive-grade thermal and ESD specifications, TSSOP16 package mapping, ripple counter timing behavior, and validated alternatives for clock tree design and automotive control logic.
Technical Context
This device implements a cascaded chain of twelve static CMOS toggle flip-flops, where each stage divides its input by two, resulting in a 4096:1 total division ratio. The asynchronous MR input forces all Q outputs LOW independent of CP state, enabling deterministic reset without clock synchronization.
Input clamping diodes support interface to voltages exceeding VCC when used with current-limiting resistors. Output drive strength is specified at ±4.0 mA (VCC = 4.5 V) and ±5.2 mA (VCC = 6.0 V), with propagation delays from CP to Q0 ranging from 14 ns (VCC = 6.0 V) to 150 ns (VCC = 2.0 V).
Key Specifications

|---|---|
| Counter stages | 12-stage binary ripple counter delivering Q0–Q11 outputs with 2¹² = 4096 count modulus |
| Supply voltage range | 2.0 V to 6.0 V - supports wide-battery automotive systems and mixed-voltage logic interfacing |
| Operating temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Max clock frequency | 98 MHz at VCC = 6.0 V, CL = 50 pF - enables high-speed timing division in engine control units |
| Propagation delay (CP→Q0) | 14 ns (typ.) at VCC = 6.0 V - defines minimum clock period for reliable counting |

FAQ
What is the difference between 74HC4040PW-Q100 and 74HCT4040PW-Q100?
The 74HC4040PW-Q100 uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), while the 74HCT4040PW-Q100 uses TTL-compatible inputs (VIH ≥ 2.0 V). Both share identical pinout, package, timing, and AEC-Q100 Grade 1 qualification. Select HC for modern CMOS systems and HCT for legacy TTL or weak-drive microcontrollers.
Can 74HC4040PW-Q100 operate at 3.3 V supply?
Yes - it is fully specified from 2.0 V to 6.0 V. At VCC = 3.3 V, VIH = 2.31 V (min), VIL = 1.09 V (max), and fmax ≈ 65 MHz (CL = 50 pF), making it suitable for mixed-voltage automotive domains such as infotainment power domains.
Is the MR input truly asynchronous and glitch-immune?
Yes - MR is asynchronous and active-HIGH; asserting MR forces all Q outputs LOW within tPHL(MR→Qn) ≤ 56 ns (VCC = 4.5 V), regardless of CP state or edge timing. No setup/hold requirements apply, and the function is immune to CP glitches during reset assertion.
Does the TSSOP16 package support reflow soldering per J-STD-020?
Yes - SOT403-1 (TSSOP16) is qualified for standard Pb-free reflow per J-STD-020D, with peak temperature rating of 260 °C. Its side-wettable flanks enable post-reflow AOI verification of solder joint integrity, required for automotive process validation.
