Product details
Overview
74HC4040DB-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 Q0–Q11 outputs. It operates from 2.0 V to 6.0 V across −40 °C to +125 °C and delivers propagation delays as low as 14 ns (VCC = 6.0 V) for CP-to-Q0. It is used in automotive timing control circuits requiring stable frequency division and reset-synchronized counting.
For engineers reviewing the 74HC4040DB-Q100 datasheet, 74HC4040DB-Q100 pinout, 74HC4040DB-Q100 application, or 74HC4040DB-Q100 equivalent, this device serves as a high-noise-immunity, CMOS-based ripple counter for automotive-grade frequency division, time delay generation, and control sequencing where deterministic reset behavior and wide supply tolerance are required.
Technical Context
The 74HC4040DB-Q100 implements a cascaded chain of twelve static toggle flip-flops, advancing only on the falling edge of CP. Its asynchronous MR input forces all Q outputs LOW independently of CP state, enabling immediate counter reset without clock dependency.
Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V), supports TTL-level inputs only in the 74HCT variant, and exhibits latch-up immunity >100 mA per JESD78 Class II Level B.

FAQ
What is the maximum clock frequency supported by the 74HC4040DB-Q100?
The 74HC4040DB-Q100 supports a maximum clock frequency of 98 MHz (typical) at VCC = 4.5 V and CL = 15 pF, and 24 MHz (minimum) across the full −40 °C to +125 °C operating range. This is determined by the CP-to-Q0 propagation delay (14 ns typ at VCC = 6.0 V) and ripple accumulation across 12 stages.
How does the asynchronous master reset (MR) behave during power-up?
The MR pin is active HIGH and asynchronously clears all 12 flip-flops to Q0–Q11 = LOW, independent of CP state or clock edges. During power-up, if MR is held HIGH until VCC stabilizes above 2.0 V, the counter begins in a known zero state - a key requirement for automotive functional safety boot sequences.
Can the 74HC4040DB-Q100 interface directly with 12 V automotive signals?
Yes - its inputs include clamp diodes to VCC and GND. When used with a series current-limiting resistor (e.g., 10 kΩ), it safely accepts 12 V signals without damage, enabling direct connection to wake-up lines or switch inputs in vehicle networks without external level-shifting circuitry.
Is the 74HC4040DB-Q100 pin-compatible with the 74HCT4040DB-Q100?
Yes - both share identical pinout, package (SSOP16/SOT338-1), and functional diagram. The sole difference is input threshold: 74HC4040DB-Q100 uses CMOS-level inputs (VIH ≈ 0.7×VCC), while 74HCT4040DB-Q100 uses TTL-compatible inputs (VIH = 2.0 V min), allowing direct replacement where input drive matches the selected variant.
