Product details
Overview
74HCT4060DB,118 from Nexperia is a 14-stage binary ripple counter/divider with integrated RC or crystal oscillator circuitry, TTL-compatible inputs (VIH = 2.0 V, VIL = 0.8 V at VCC = 5.0 V), 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 and supports timing functions in industrial control panels requiring stable low-power clock division.
For engineers reviewing the 74HCT4060DB,118 datasheet, 74HCT4060DB,118 pinout, 74HCT4060DB,118 application, or 74HCT4060DB,118 equivalent, this device serves as a self-contained oscillator + divider for precision time-delay circuits, programmable timers, and frequency scaling where TTL-level drive compatibility and wide temperature operation are required.
Technical Context
The 74HCT4060DB,118 implements a synchronous-free ripple-carry architecture where each stage divides by two, yielding Q3 (÷8) through Q13 (÷8192). Its oscillator section uses RS (input/clock), RTC (resistor terminal), and CTC (capacitor terminal) to configure either RC networks (fosc ≈ 1/(2.2 × Rt × Ct)) or parallel-resonant crystals - with external clock injection permitted at RS while leaving RTC/CTC floating.
Master reset (MR, active HIGH) forces all outputs LOW independently of clock edge or oscillator state. Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors, and output drive capability is specified at ±4.0 mA (VOL ≤ 0.4 V, VOH ≥ 3.7 V at VCC = 4.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL logic rails and robust noise margin under industrial supply variation. |
| Input threshold (VIH/VIL) | 2.0 V / 0.8 V at VCC = 5.0 V - guarantees direct interfacing with legacy 5 V TTL outputs without level translation. |
| Max clock frequency (RS) | 80 MHz at VCC = 4.5 V - supports high-speed division for sub-10 ns timing resolution in Q3 output path. |
| Propagation delay (RS→Q3) | 33 ns to 66 ns (typ/max) - enables predictable timing chain design for cascaded counters or delay generators. |
| Output drive (IO) | ±4.0 mA at VCC = 4.5 V - sufficient to directly drive multiple 74-series inputs or small LED indicators via series resistor. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, motor drives, and industrial PLC timing subsystems. |
| Power dissipation (ICC) | 8.0 μA typical, 160 μA max at VCC = 5.5 V - enables battery-backed timer applications with multi-year standby life. |
Pinout & Package
74HCT4060DB,118 is supplied in SSOP16 (SOT338-1) package: plastic shrink small outline, 16 leads, body width 5.3 mm, 0.65 mm pitch. Pin 1 index located at top-left corner with beveled edge marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q11) | Counter output | ÷2048 divided clock signal; buffered, rail-to-rail CMOS output capable of driving 10 LSTTL loads. |
| 2 (Q12) | Counter output | ÷4096 divided clock; identical electrical specs to Q11, used for extended timing intervals or cascade enable. |
| 3 (Q13) | Counter output | ÷8192 output; highest division ratio; commonly used as watchdog timeout signal or long-interval interrupt source. |
| 4 (Q5) | Counter output | ÷32 output; frequently selected for mid-range timing (e.g., 32 ms at 1 kHz input) in microcontroller peripheral coordination. |
| 5 (Q4) | Counter output | ÷16 output; matches common baud rate divisors and PWM prescaler requirements in embedded serial interfaces. |
| 6 (Q6) | Counter output | ÷64 output; used in audio tone generation, stepper motor step timing, or ADC sampling clock derivation. |
| 7 (Q3) | Counter output | ÷8 output; lowest division stage; shortest propagation delay (33 ns typ), ideal for fast feedback loops. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and oscillator currents; must be low-impedance connection to system ground plane. |
| 9 (CTC) | Oscillator capacitor terminal | Connects external timing capacitor (Ct); value sets RC oscillator frequency alongside RTC; requires low-leakage ceramic type. |
| 10 (RTC) | Oscillator resistor terminal | Connects external timing resistor (Rt); forms RC network with CTC; recommended range 10 kΩ to 1 MΩ for stability. |
| 11 (RS) | Clock input / oscillator node | Accepts external clock (TTL levels) or serves as oscillator output in crystal/RC configurations; rising edge triggers count advance. |
| 12 (MR) | Asynchronous master reset | Active-HIGH signal; clears all 14 stages immediately regardless of RS state; requires pull-down or controlled driver. |
| 13 (Q8) | Counter output | ÷256 output; widely used in real-time clock second-hand division (e.g., 256 Hz → 1 Hz with additional logic). |
| 14 (Q7) | Counter output | ÷128 output; supports intermediate timing windows in sequence controllers and cyclic redundancy check (CRC) clocking. |
| 15 (Q9) | Counter output | ÷512 output; employed in power supply soft-start sequencing, thermal monitoring intervals, and watchdog window extension. |
| 16 (VCC) | Positive supply | 5 V nominal supply; decoupling capacitor (100 nF X7R) required within 5 mm of pin to suppress switching noise on internal oscillator. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Guaranteed VIH = 2.0 V and VIL = 0.8 V at VCC = 5.0 V - eliminates need for level shifters when interfacing with 74LS, 74F, or microcontroller GPIOs. |
| Dual oscillator configuration | Supports both RC networks (Rt = 10 kΩ–1 MΩ, Ct > 50 pF) and parallel-resonant crystals (e.g., 32.768 kHz) - enables flexible timing source selection per application. |
| Asynchronous master reset | MR forces all outputs LOW within 21 ns (max) at VCC = 4.5 V - provides deterministic initialization for safety-critical or fault-recovery sequences. |
| Industrial temperature range | Specified from –40 °C to +125 °C - validated for use in motor control enclosures, solar inverters, and railway signaling hardware. |
| Low dynamic power | CPD = 40 pF - limits switching power to < 1 mW at 1 MHz input (PD = CPD × VCC² × fi), critical for thermally constrained PCB layouts. |
Applications
| Industrial Timer Module | Microcontroller Watchdog Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 14-stage ripple counter with oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4060DB,118 | CMOS input thresholds (VIH = 3.6 V @ VCC = 4.5 V); wider 2.0–6.0 V supply range | Better suited for mixed-voltage systems (e.g., 3.3 V MCU controlling 5 V peripherals) due to higher noise immunity | Select when interfacing with CMOS or mixed-supply logic; avoid in pure 5 V TTL environments without level adaptation |
| CD4060BE | Single-supply 3–15 V operation; slower max fosc (3 MHz @ 5 V); no TTL input compatibility | Used in legacy analog-digital hybrid designs (e.g., VCO-based function generators) where low cost and wide VCC tolerance outweigh speed | Choose for ultra-low-cost consumer electronics or educational kits where timing precision and speed are secondary |

FAQ
Can the 74HCT4060DB,118 operate with a 3.3 V supply?
No. The 74HCT4060DB,118 is specified only for 4.5 V to 5.5 V operation. Its TTL-compatible inputs require minimum VIH = 2.0 V, but internal logic thresholds and output drive strength are not characterized below 4.5 V. For 3.3 V systems, use the 74LVC4060 or 74AUP1G4060 instead.
What is the maximum recommended value for Rt in the RC oscillator configuration?
The datasheet specifies Rt ≤ 1 MΩ for stable oscillation and start-up reliability. At Rt = 1 MΩ and Ct = 100 pF, typical fosc ≈ 4.5 kHz. Exceeding 1 MΩ increases susceptibility to noise-induced jitter and may prevent oscillation under temperature extremes or process variation.
Is the SSOP16 (SOT338-1) package of 74HCT4060DB,118 RoHS compliant and lead-free?
Yes. The 74HCT4060DB,118 in SSOP16 packaging meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations (matte tin plating) and halogen-free molding compound, certified per Nexperia's Declaration of Conformity (DocID: NEX_RoHS_74HCT4060DB).
How does the master reset (MR) interact with the oscillator when asserted?
MR is fully asynchronous and overrides all internal oscillator and counter activity. When MR = HIGH, all flip-flops reset immediately, forcing Q3–Q9 and Q11–Q13 LOW regardless of RS state or oscillator phase. The oscillator circuit remains powered but ceases toggling until MR returns LOW and RS receives a valid HIGH-to-LOW transition.
