Product details
Overview
74HC4020BQ-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 14-stage binary ripple counter with asynchronous master reset (MR), clock input (CP), and 12 buffered outputs (Q0, Q3–Q13). It advances on the HIGH-to-LOW CP edge, operates from 2.0 V to 6.0 V, and delivers propagation delays as low as 11 ns at VCC = 6.0 V - used in automotive timing and frequency division circuits.
For engineers reviewing the 74HC4020BQ-Q100 datasheet, 74HC4020BQ-Q100 pinout, 74HC4020BQ-Q100 application, or 74HC4020BQ-Q100 equivalent, key selection factors include its automotive qualification, DHVQFN16 package with side-wettable flanks for AOI, CMOS-level input compatibility, 14-bit divide-by-16384 capability, and guaranteed operation from –40 °C to +125 °C.
Technical Context
This device implements a cascaded chain of 14 static toggle flip-flops, forming a synchronous-free ripple counter where each stage divides the preceding stage's output by two. The MR input is asynchronous and active-HIGH, forcing all outputs LOW regardless of CP state.
Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Output drive strength is specified at ±4.0 mA (VOH/VOL) under 4.5 V supply, supporting direct connection to standard CMOS loads without buffering.

Use Value: Eliminates need for external RC timers or microcontroller GPIO timing loops, reducing BOM count and firmware complexity. | Use Scenario: Deriving lower-frequency sampling clocks for analog sensor interfaces (e.g., MAP, IAT) from a high-speed system oscillator. IC Role / Device Role / Timing Role: Frequency divider delivering stable sub-MHz clocks (e.g., Q13 = ÷8192) with deterministic jitter behavior. Use Value: Provides jitter-controlled clock edges independent of MCU load, improving ADC conversion accuracy and repeatability. |
| Infotainment System Power Sequencing | ADAS Camera Module Reset Coordination |
Use Scenario: Controlling staggered power-up sequence of display driver, audio codec, and USB PHY ICs during system boot.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 14-stage binary ripple counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT4020BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5–5.5 V), otherwise identical timing and packaging | Better suited for legacy 5 V TTL systems or mixed-signal boards with both CMOS and TTL logic | Select when interfacing directly to 5 V TTL outputs without level translation |
| SN74HC4020QPWRQ1 | Texas Instruments variant in TSSOP-16 (SOT403-1); same electrical specs but different package and thermal profile | Lacks side-wettable flanks; less suitable for AOI-dependent automotive production lines | Choose only if board layout requires TSSOP footprint or TI supply-chain alignment is mandated |
Compared with 74HCT4020BQ-Q100, the HC version offers higher noise immunity in mixed-voltage environments; versus SN74HC4020QPWRQ1, the DHVQFN package provides superior thermal performance and automated inspection capability critical for automotive manufacturing.

FAQ
What is the maximum operating frequency of the 74HC4020BQ-Q100?
The maximum clock frequency is 109 MHz at VCC = 6.0 V and CL = 15 pF, dropping to 24 MHz at VCC = 6.0 V and CL = 50 pF. This reflects the device's ability to operate at high speeds in low-capacitance signal paths while maintaining timing integrity across its full automotive temperature range.
Can the MR pin be left unconnected in a circuit?
No - MR is active-HIGH and internally unconnected (no pull-down). Leaving it floating risks unintended resets due to noise coupling. It must be actively driven LOW (e.g., via 10 kΩ pull-down resistor or controlled logic signal) during normal operation to prevent spurious clearing of the counter.
Does the DHVQFN16 package require soldering of the exposed thermal pad?
The thermal pad (terminal 1 index area) has no electrical function and does not require soldering. If soldered, it must remain electrically floating or be connected to VCC - never to GND - to avoid violating internal bias conditions and compromising latch-up immunity.
How many outputs does the 74HC4020BQ-Q100 provide, and which bits are missing?
It provides 12 buffered outputs: Q0 and Q3 through Q13. Bits Q1 and Q2 are not externally available - this is inherent to the 74HC4020 architecture and confirmed in the functional diagram and pin description table. Only Q0 and Q3–Q13 are routed to package terminals.
