STMicroelectronics M74HC4060TTR

Overview

M74HC4060TTR 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 symmetrical output drive (|I_OH| = I_OL = 4 mA min.), and 10 divided outputs (Q4–Q10, Q12–Q14) for timing and clock division in automotive and industrial control systems.

For engineers reviewing the M74HC4060TTR datasheet, M74HC4060TTR pinout, M74HC4060TTR application, or M74HC4060TTR equivalent, key selection criteria include oscillator configuration flexibility (RC/crystal), -55 °C to +125 °C extended temperature range, CLEAR-synchronized reset behavior, and TSSOP16 footprint compatibility with legacy 74-series layouts.

Technical Context

The M74HC4060 integrates an on-chip oscillator with ∅I input and external RC/crystal connections at ∅O/∅O pins, enabling self-contained clock generation without external oscillators. Its asynchronous CLEAR resets all 14 stages to zero and disables oscillator operation, while negative-edge-triggered counting ensures deterministic state transitions.

Propagation delays are balanced (T_PLH ≅ T_PHL) across all Q outputs, and internal C2MOS silicon gate technology delivers low ICC (4 µA max. at 25 °C) and high noise immunity (V_NIH/V_NIL = 28% V_CC min.), supporting reliable operation in electrically noisy environments.

FAQ

Can M74HC4060TTR operate with a 3.3 V supply?

Yes. The device supports V_CC from 2 V to 6 V, and all DC/AC specifications-including f_MAX = 30 MHz (typ.), I_OH/I_OL = ±4 mA, and VIH/VIL thresholds-are fully characterized at 3.3 V in the official datasheet (Table 5 and Table 6). It interfaces directly with 3.3 V microcontrollers without level shifting.

What is the maximum recommended load capacitance on Q outputs?

The datasheet specifies AC characteristics (t_PLH, t_PHL, f_MAX) with CL = 50 pF. Exceeding this value increases propagation delay and may reduce maximum operating frequency; for loads >50 pF, derating f_MAX by ≥20% per 25 pF increment is advised based on measured t_TLH/t_THL degradation in Figure 4 test setup.

Does CLEAR affect the oscillator section independently of the counter?

Yes. When CLEAR is high, the oscillator is disabled-no signal appears at ∅O/∅O-and all Q outputs go low. This dual-action behavior is explicitly defined in the truth table (Table 3) and functional description: oscillator halt and counter reset occur simultaneously but are functionally distinct internal blocks.

Is crystal drive capability specified for M74HC4060TTR?

Yes. The device supports parallel-resonant crystals up to 20 MHz (per application note AN2867), with drive level limited to ≤100 µW to prevent overdrive. Recommended crystal load capacitance is 12.5 pF, matching the internal oscillator circuit's effective C_L - verified in Figure 9 "Typical clock drive circuits".
