Product details
Overview
74HCT4060BQ-Q100 from Nexperia is an automotive-grade 14-stage binary ripple counter/divider with integrated RC/crystal oscillator, TTL-compatible inputs, 10 buffered outputs (Q3–Q9, Q11–Q13), and asynchronous master reset (MR). It operates from 4.5 V to 5.5 V across –40 °C to +125 °C, supports up to 80 MHz input clock frequency at VCC = 4.5 V, and delivers propagation delays as low as 33 ns (RS→Q3), enabling precise timing in engine control units and ADAS domain controllers.
For engineers reviewing the 74HCT4060BQ-Q100 datasheet, 74HCT4060BQ-Q100 pinout, 74HCT4060BQ-Q100 application, or 74HCT4060BQ-Q100 equivalent, this page provides verified functional architecture, DHVQFN16 package terminal mapping, automotive AEC-Q100 Grade 1 qualification status, oscillator design constraints (Rt = 10 kΩ–1 MΩ, Ct > 50 pF), and validated alternatives for timing-critical automotive subsystems.
Technical Context
The device implements a synchronous 14-bit ripple-carry counter with oscillator circuitry that accepts either external clock at RS or internal RC/crystal configuration via RTC/CTC pins. Counter advances on HIGH-to-LOW transition of RS; MR forces all outputs LOW asynchronously. Input clamping diodes allow interface to voltages exceeding VCC using current-limiting resistors.
Oscillator operation supports two modes: RC mode (RtCt time constant dominates frequency) and crystal mode (with Rbias and load capacitors C2/C3). For RC mode, recommended Rt = 10 kΩ–1 MΩ and Ct > 50 pF ensure stable start-up and accuracy; for crystal mode, R2 ≈ 2.2 kΩ and C3 = 22–37 pF are typical. Output drive strength is ±4.0 mA at VCC = 4.5 V.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
Can the 74HCT4060BQ-Q100 operate with a 3.3 V supply?
No. The 74HCT4060BQ-Q100 is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. At 3.3 V, input thresholds (VIH = 2.0 V min) become marginal, and propagation delays increase beyond specification-potentially causing timing violations in automotive systems. Use 74LVC4060 for 3.3 V applications.
What happens if RTC and CTC pins are left unconnected while using external clock at RS?
RTC and CTC must be left floating-not tied to VCC or GND-when RS is driven by an external clock. Connecting them risks unintended oscillator feedback, causing metastability or erratic counting behavior. The datasheet explicitly states "keep the oscillator pins (RTC and CTC) floating" in this configuration.
Is the exposed thermal pad on the DHVQFN16 package electrically connected internally?
No. The exposed pad (terminal 1 index area) has no internal electrical connection. Per datasheet note: "This is not a supply pin. There is no electrical or mechanical requirement to solder the pad." If soldered, it must remain floating or be connected to VCC-never to GND-to avoid compromising ESD performance.
How does the master reset (MR) interact with ongoing oscillator activity?
MR is asynchronous and overrides all internal oscillator and counting functions. When MR is asserted HIGH, all flip-flops reset immediately-regardless of RS state or oscillator phase-and all Q outputs go LOW within tPHL (max 44 ns at VCC = 4.5 V). Oscillation halts until MR returns LOW and RS resumes valid transitions.
