Nexperia USA Inc. 74HC4060D,652

Overview

74HC4060D,652 from Nexperia is a 14-stage binary ripple counter/divider with integrated RC or crystal oscillator circuitry, featuring asynchronous master reset (MR), 10 buffered outputs (Q3–Q9, Q11–Q13), and oscillator terminals (RS, RTC, CTC). It operates from 2.0 V to 6.0 V, delivers propagation delays as low as 6 ns at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C) in SO16 package - used in precision timing circuits requiring stable frequency division.

For engineers reviewing the 74HC4060D,652 datasheet, 74HC4060D,652 pinout, 74HC4060D,652 application, or 74HC4060D,652 equivalent, key selection criteria include oscillator configuration flexibility (RC vs. crystal), output stage count (14-bit binary division up to 2¹⁴), TTL/CMOS input compatibility (HC variant), and SO16 thermal performance under continuous clocking.

Technical Context

The device implements a synchronous-free ripple-carry architecture where each stage advances on the HIGH-to-LOW transition of RS, enabling cascaded timing without global clock distribution. Its oscillator section supports two modes: external crystal (with bias resistor R₂ and load capacitors C₂/C₃) or RC network (R_t, C_t), with recommended R_t = 10 kΩ–1 MΩ and C_t > 50 pF for stable startup.

Input clamping diodes allow safe interfacing to voltages exceeding V_CC when current-limiting resistors are used. All outputs are CMOS-compatible, 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 74HC4060D,652 operate with a crystal oscillator?

Yes - pins RTC and CTC connect to crystal and load capacitors per Figure 11 in the datasheet, with R₂ = 2.2 kΩ providing bias. The oscillator starts reliably with fundamental-mode crystals from 100 kHz to 12 MHz, and the internal inverter provides sufficient gain for sustained oscillation without external amplification.

What happens if RTC and CTC are left unconnected while using an external clock on RS?

RTC and CTC must be left floating when RS is driven by an external clock. Connecting them to VCC or GND may cause latch-up or unpredictable oscillation due to internal node contention. The datasheet explicitly states "keep the oscillator pins (RTC and CTC) floating" in this configuration to prevent unintended feedback paths.

How does the master reset (MR) interact with ongoing oscillator operation?

MR is asynchronous and overrides all internal states: when asserted HIGH, it immediately clears all 14 flip-flops and forces all Q outputs LOW, regardless of RS activity or oscillator phase. Oscillation halts during MR assertion and resumes only after MR returns LOW and RS transitions HIGH-to-LOW - no re-start delay is specified.

Is the SO16 package thermally adequate for continuous 6 V, 10 MHz operation?

Yes - the SOT109-1 package has P_tot = 500 mW at T_amb ≤ 110 °C, derating linearly at 12.4 mW/K above that. At 10 MHz with CL = 50 pF, dynamic power is ~1.2 mW (CPD × VCC² × f = 40 pF × 36 V² × 10 MHz), well below thermal limits even at full ambient rating.
