STMicroelectronics M74HC4060B1R

Overview

M74HC4060B1R from STMicroelectronics is a high-speed CMOS 14-stage binary counter/oscillator with RC or crystal oscillator configuration, 65 MHz max clock frequency at 6 V, 2–6 V operating voltage range, and pin/function compatibility with standard 74 series 4060. It delivers Q4–Q14 divided outputs (including 1/16384 division at Q12) and features master reset via active-high CLEAR input.

For engineers reviewing the M74HC4060B1R datasheet, M74HC4060B1R pinout, M74HC4060B1R application, or M74HC4060B1R equivalent, key selection criteria include oscillator flexibility (RC/crystal), wide temperature range (−55 °C to +125 °C), low ICC (4 μA typ.), symmetrical output drive (±4 mA), and automotive-grade variants with AEC-Q100 qualification.

Technical Context

The M74HC4060B1R integrates an on-chip oscillator circuit with ∅I input and external ∅O/∅O pins for resistor-capacitor or crystal-based timing networks. Its 14-bit ripple counter advances on each negative edge of the oscillator output, producing ten discrete frequency-divided outputs (Q4–Q10, Q12–Q14).

Reset is synchronous and active-high on CLEAR, forcing all Q outputs low and disabling oscillator operation. Propagation delays are balanced (TPLH ≅ TPHL), and input thresholds meet 28% VCC noise immunity minimum across 2–6 V supply.

Key Specifications

FAQ

What oscillator configurations does M74HC4060B1R support?

M74HC4060B1R supports both RC and crystal oscillator topologies. Pins ∅O and ∅O connect to external R and C for RC mode; ∅I accepts crystal between ∅O and ∅O in parallel-resonant configuration. No external inverter is needed-the internal amplifier enables self-oscillation with standard 32.768 kHz or 1–10 MHz crystals.

How does the CLEAR function interact with oscillator operation?

When CLEAR is driven high, all Q outputs go low and the internal oscillator is disabled-halting all counting activity. Oscillation resumes only after CLEAR returns low and a valid negative edge appears on ∅I. This behavior is confirmed in Table 3 (Truth table) and Figure 2 (Logic diagram) of the datasheet.

Can M74HC4060B1R drive multiple CMOS inputs directly?

Yes. With guaranteed |IOH| = |IOL| ≥ 4 mA at VCC = 6 V, M74HC4060B1R can directly drive up to 10 standard 74HC inputs (each requiring ~1 μA) or 2–3 74LS inputs (each ~0.4 mA). Fanout is limited by capacitive loading-keep total load ≤ 50 pF per output to maintain specified tPLH/tPHL.

Is M74HC4060B1R suitable for battery-powered applications?

Yes. At VCC = 3.3 V and TA = 25 °C, ICC is ≤ 4 μA (typical), and Q12 output enables 1 Hz wake-up signaling from a 32.768 kHz crystal. Combined with SO16's low thermal resistance and −55 °C to +125 °C rating, it supports 10+ year deployments in sealed battery-operated meters and remote sensors.
