STMicroelectronics M74HC4060YTTR

Overview

M74HC4060YTTR from STMicroelectronics is a high-speed CMOS 14-stage binary counter/oscillator in TSSOP16 package, operating from 2 V to 6 V supply, delivering f_MAX = 65 MHz (typ.) at V_CC = 6 V, with Q12 providing 1/16384 frequency division, and qualified per AEC-Q100 for automotive applications including engine control timing and body electronics clocking.

For engineers reviewing the M74HC4060YTTR datasheet, M74HC4060YTTR pinout, M74HC4060YTTR application, or M74HC4060YTTR equivalent, key selection considerations include oscillator configuration flexibility (RC/crystal), automotive-grade temperature range (–40 °C to +125 °C), symmetrical output drive (±4 mA), low ICC (4 µA max), and noise immunity (V_NIH/V_NIL ≥ 28% V_CC).

Technical Context

The device integrates an on-chip oscillator with ∅I, ∅O, and ∅O pins enabling RC or crystal-based clock generation, while its asynchronous CLEAR input resets all 14 stages to zero and disables oscillation. Counter outputs Q4–Q10 and Q12–Q14 provide ten discrete division ratios, with propagation delays balanced (t_PLH ≅ t_PHL) and pulse width constraints defined for both clock and reset inputs.

It uses silicon gate C2MOS technology for low power and high noise immunity, supports wide voltage operation (2–6 V), and features ESD protection (HBM: 2 kV, MM: 200 V, CDM: 1 kV). The oscillator section includes internal feedback path and external component connections for frequency stability tuning.

FAQ

Can M74HC4060YTTR operate with a 3.3 V supply?

Yes. The device supports V_CC from 2 V to 6 V, and all electrical characteristics-including f_MAX = 30 MHz (typ.), I_OH/I_OL = ±4 mA, and V_NIH/V_NIL ≥ 28% V_CC-are fully specified at 3.3 V per Table 5 and Table 6 of the datasheet. It interfaces directly with 3.3 V microcontrollers without level shifters.

What is the minimum external resistor value for RC oscillator configuration?

The minimum recommended R value is 2 kΩ, based on oscillator startup reliability and power dissipation limits. With C = 22 pF and R = 2 kΩ, typical frequency is ~3.5 MHz; lower R values risk excessive current through ∅O/∅O pins and may impair oscillation stability or increase jitter.

Does CLEAR affect the oscillator section independently of the counter?

Yes. When CLEAR is high, both the counter outputs are forced low and the internal oscillator is disabled-halting all clock generation. This dual-action behavior is explicitly confirmed in the Functional Description section: "A high level on the CLEAR accomplishes the reset function, i.e. all counter outputs are made low and the oscillator is disabled."

Is crystal oscillator configuration supported with fundamental-mode 32.768 kHz tuning forks?

Yes. The oscillator circuit supports fundamental-mode 32.768 kHz crystals via ∅I, ∅O, and ∅O pins. Layout guidelines recommend keeping traces short and symmetric, and adding optional load capacitors (12.5 pF typical) per Figure 9 in the datasheet to ensure reliable startup and frequency accuracy within ±20 ppm over temperature.
