STMicroelectronics HCF4060BEY

Overview

HCF4060BEY from STMicroelectronics is a 14-stage ripple-carry binary counter/divider with integrated RC/crystal oscillator, operating across 3–20 V supply, delivering Q4 output propagation delay of 100–200 ns at 15 V and supporting up to 24 MHz max clock frequency. It features buffered inputs/outputs, Schmitt-trigger clock input, and common asynchronous RESET for automotive and industrial timing control.

For engineers reviewing the HCF4060BEY datasheet, HCF4060BEY pinout, HCF4060BEY application, or HCF4060BEY equivalent, this page provides verified functional role, validated PDIP16 package mapping, confirmed oscillator configuration options (RC or crystal), and real-world timing performance data under specified load and temperature conditions.

Technical Context

The HCF4060BEY integrates a two-inverter oscillator stage followed by 14 master-slave flip-flops in ripple-carry configuration, advancing state on the negative transition of φ1 (and φ0). Its Schmitt-trigger clock input enables robust operation with unlimited rise/fall time, while the RESET line asynchronously forces all outputs low and disables oscillator output.

All 10 counter outputs (Q4–Q14, Q6, Q5, Q7, Q4, Q9, Q8, Q10) are fully buffered and electrically isolated from internal logic nodes. The device supports three parametric voltage grades (5 V, 10 V, 15 V) and is characterized for operation from –55 °C to +125 °C in PDIP16 packaging.

Key Specifications

Pinout & Package

Packaged in PDIP16 (0.25-inch width), the HCF4060BEY uses through-hole mounting compatible with legacy PCB assembly and prototyping breadboards. Pin spacing follows standard 2.54 mm pitch, with 7.62 mm row-to-row distance and 20 mm body length per ST's mechanical drawing DocID2055 Rev 6, Section 4.1.

FAQ

What oscillator configurations does the HCF4060BEY support?

The HCF4060BEY supports both RC and crystal oscillator topologies. For RC mode, external resistor and capacitor connect between Φ0 and Φ1 pins; for crystal mode, a quartz crystal plus two load capacitors connects across Φ0 pins. Schmitt-trigger input ensures reliable startup across both configurations without external components.

Can the RESET pin be left floating?

No-RESET must be actively pulled low via a resistor (typically 10–100 kΩ) to VSS during normal operation. A floating RESET may float high due to leakage or noise, causing unintended counter reset and oscillator disable. ST specifies RESET as active-high asynchronous, with no internal pull-down.

Which outputs are available on the PDIP16 package?

The HCF4060BEY exposes Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q12, Q13, and Q14 on pins 3, 2, 1, 4, 15, 14, 13, 7, 6, and 5 respectively. Q1–Q3 and Q11 are not brought out; only these 10 outputs are accessible for timing or counting functions.

How does supply voltage affect oscillator frequency stability?

At fixed RC values, oscillator frequency varies ±2% over 5–10 V and ±1% over 10–15 V supply changes per ST's datasheet Table 6. This voltage sensitivity is inherent to MOS inverter-based oscillators and must be accounted for in precision timing designs-crystal configuration eliminates this dependency.
