Nexperia USA Inc. 74HCT4060DB-Q100J

Overview

74HCT4060DB-Q100 from Nexperia is an automotive-grade 14-stage binary ripple counter/divider with integrated RC/crystal oscillator, TTL-compatible inputs, 10 buffered outputs (Q3–Q9, Q11–Q13), and asynchronous master reset (MR). It operates from 4.5 V to 5.5 V, supports -40 °C to +125 °C ambient, and delivers f_MAX = 80 MHz at V_CC = 4.5 V - used in engine control timing, ADAS clock division, and infotainment system delay generation.

For engineers reviewing the 74HCT4060DB-Q100 datasheet, 74HCT4060DB-Q100 pinout, 74HCT4060DB-Q100 application, or 74HCT4060DB-Q100 equivalent, key selection criteria include TTL-level input compatibility, AEC-Q100 Grade 1 qualification, oscillator terminal flexibility (RS/RTC/CTC), and ripple-counter propagation delay (t_pd = 33 ns typical to Q3 at 4.5 V).

Technical Context

This device implements a synchronous-free, asynchronous ripple-carry architecture where each stage divides by two, yielding Q3 (÷8), Q9 (÷512), Q13 (÷8192). The oscillator section supports both external crystal (via RTC/CTC) and RC networks, with RS serving as either oscillator output or external clock input - enabling flexible clock tree design without additional logic.

Input clamping diodes allow safe interfacing to voltages exceeding V_CC when current-limiting resistors are used. MR is active-HIGH and overrides all counter states independently of clock edge or oscillator activity, ensuring deterministic reset behavior critical for automotive safety-critical timing recovery.

FAQ

Can the 74HCT4060DB-Q100 operate with a 3.3 V supply?

No - the 74HCT4060DB-Q100 is specified only for 4.5 V to 5.5 V operation. Its TTL-compatible input thresholds (VIH = 2.0 V min on MR, 3.6 V min on RS) require ≥4.5 V V_CC to guarantee proper logic recognition. For 3.3 V systems, use the pin-compatible 74HC4060BQ-Q100 variant instead.

What happens to outputs when MR is asserted HIGH?

When MR is driven HIGH, all 14 counter stages reset synchronously, forcing Q3–Q9 and Q11–Q13 LOW immediately - regardless of RS clock state or oscillator activity. This override occurs within t_PHL = 44 ns (max) at V_CC = 4.5 V, and outputs remain LOW until MR returns LOW and at least one RS falling edge occurs.

Is external loading required on RTC and CTC pins when using an external clock on RS?

Yes - when RS is driven by an external clock, RTC and CTC must be left floating (unconnected) per datasheet Section 1. General description. No pull-up, pull-down, or capacitive loading is permitted on these pins in external-clock mode, as residual capacitance can cause unintended oscillator coupling or increased EMI susceptibility.

Does the DHVQFN16 package require special PCB layout considerations?

Yes - the SOT763-1 DHVQFN16 package requires a thermal pad (exposed die attach area) connected to a solid GND plane via ≥4 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). Solder mask defined pads and stencil aperture reduction to 75% are recommended to prevent solder bridging on side-wettable flanks during reflow.
