Nexperia USA Inc. 74HC4060DB,118

Overview

74HC4060DB,118 from Nexperia is a 14-stage binary ripple counter/divider with integrated RC or crystal oscillator circuitry, featuring 10 buffered outputs (Q3–Q9, Q11–Q13), asynchronous master reset (MR), and oscillator terminals (RS, RTC, CTC). It operates from 2.0 V to 6.0 V, delivers propagation delays as low as 29 ns at 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). Used in precision timing circuits where stable frequency division and low-power clock generation are required.

For engineers reviewing the 74HC4060DB,118 datasheet, 74HC4060DB,118 pinout, 74HC4060DB,118 application, or 74HC4060DB,118 equivalent, key selection criteria include oscillator configuration flexibility (RC vs. crystal), output stage count and tap points (Q3–Q13), MR assertion behavior (active-HIGH asynchronous clear), supply voltage compatibility (2.0–6.0 V), and package thermal performance in TSSOP16.

Technical Context

The device implements a synchronous-free ripple-carry architecture where each stage advances on the HIGH-to-LOW transition of the RS input - whether derived from internal oscillator or external clock. Its oscillator section supports two configurations: RC network (Rt/CTC, RTC/Ct) with designable frequency range (≈1 kHz to >1 MHz), or parallel-resonant crystal (e.g., 32.768 kHz or 1 MHz) with bias resistor and load capacitors.

Input clamping diodes enable overvoltage-tolerant interfacing via current-limiting resistors. All outputs are CMOS-level buffered, with VOH ≥ 4.4 V and VOL ≤ 0.26 V at VCC = 4.5 V and IO = ±4.0 mA, ensuring robust noise immunity and fan-out capability across mixed-voltage systems.

FAQ

Can the 74HC4060DB,118 operate with a 3.3 V supply?

Yes. The device is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, typical propagation delay is ≈45 ns (RS→Q3), VIH is 2.3 V min, and VOL remains ≤0.33 V at 4 mA sink - ensuring compatibility with 3.3 V microcontrollers and logic families without level translation.

What is the recommended crystal configuration for stable 32.768 kHz operation?

For 32.768 kHz crystal use, connect a 12 pF load capacitor from RTC to ground, a 22–37 pF capacitor from CTC to ground, and a 2.2 kΩ resistor (R2) between RS and RTC. Bias resistor (100 kΩ to 1 MΩ) connects from VCC to RS. This matches Nexperia's Fig. 11 crystal oscillator topology and ensures reliable start-up and frequency accuracy.

How does the master reset (MR) interact with the oscillator during reset assertion?

MR is asynchronous and overrides all internal oscillator and counter activity. When MR = HIGH, all flip-flops reset immediately, forcing Q3–Q13 LOW regardless of RS state or oscillator phase. The oscillator circuit remains powered but its output is gated - no toggling occurs at RS until MR returns LOW and the first valid clock edge arrives.

Is the exposed thermal pad on the TSSOP16 package electrically connected?

No. The exposed pad on the 74HC4060DB,118 (TSSOP16/SOT403-1) is not electrically connected to any internal node. Per Nexperia's datasheet Section 6.1, it may remain floating or be soldered to VCC for improved thermal conduction - but no electrical connection is required or implied.
