Nexperia USA Inc. 74HC4060BQ-Q100,11

Overview

74HC4060BQ-Q100 from Nexperia is an automotive-qualified 14-stage binary ripple counter/divider with integrated RC or crystal oscillator circuitry, operating from 2.0 V to 6.0 V, featuring 10 buffered outputs (Q3–Q9, Q11–Q13), asynchronous master reset (MR), and DHVQFN16 package. It serves as a timing engine in engine control units, body electronics, and ADAS subsystems requiring stable frequency division and low-jitter clock generation.

For engineers reviewing the 74HC4060BQ-Q100 datasheet, 74HC4060BQ-Q100 pinout, 74HC4060BQ-Q100 application, or 74HC4060BQ-Q100 equivalent, key selection criteria include oscillator configuration flexibility (RC vs. crystal), AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), propagation delay consistency across temperature, output drive capability at 4.5 V, and compatibility with CMOS-level input thresholds.

Technical Context

The device implements a synchronous 14-bit ripple-carry counter architecture where each stage advances on the HIGH-to-LOW transition of the RS input. Its oscillator section supports two configurations: external RC network (via RTC/CTC pins) or parallel-resonant crystal (with bias resistor and load capacitors), enabling precise frequency tuning from ~1 kHz to >95 MHz depending on supply and load.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The MR pin overrides all counter states asynchronously, forcing all outputs LOW regardless of clock or oscillator activity - critical for deterministic system initialization in automotive safety-critical modules.

Key Specifications

Pinout & Package

DHVQFN16 package (SOT763-1), 2.5 × 3.5 × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection. No leads; 16 terminals arranged in quad configuration with exposed thermal pad (not electrically connected unless tied to VCC or left floating).

Compared with 74HC4060BQ-Q100, the 74HCT4060BQ-Q100 offers seamless integration into 5 V TTL ecosystems but sacrifices some noise margin at low VCC, while CD4060BM96 trades automotive reliability and speed for ultra-wide supply flexibility - making the HC variant optimal for modern 3.3 V/5 V automotive timing nodes.

FAQ

Can the 74HC4060BQ-Q100 operate with a crystal oscillator at 32.768 kHz?

Yes - the device supports crystal oscillator configuration with typical load capacitance values of 22 pF to 37 pF and a bias resistor of 100 kΩ to 1 MΩ. At 32.768 kHz, Q15 (not present) would yield 1 Hz, but Q13 delivers 4 Hz, enabling low-power real-time clock division in body control modules without external counters.

What is the minimum recommended Rt value for reliable RC oscillator startup?

Nexperia specifies Rt ≥ 1 kΩ to avoid startup failures. For stable operation across -40 °C to +125 °C, use Rt = 10 kΩ to 100 kΩ with Ct ≥ 50 pF. Lower Rt values increase current draw and reduce frequency stability; values below 1 kΩ risk failure to oscillate at cold temperatures.

How does the MR pin behave during power-up sequencing?

The MR pin is active-HIGH and asynchronous. During power ramp-up, if MR is held HIGH until VCC exceeds 1.5 V (at 2.0 V supply), all outputs remain LOW until MR is deasserted. This ensures deterministic reset state before first clock edge - critical for avoiding spurious pulses in safety-critical actuator drivers.

Is the exposed thermal pad on the DHVQFN16 package electrically connected?

No - the thermal pad (terminal 1 index area) has no internal electrical connection. Nexperia states it may remain floating or be connected to VCC; if soldered, it must not be tied to GND or any other potential to prevent latch-up or undefined behavior in the oscillator circuit.
