Nexperia USA Inc. HEF4060BT,653

Overview

HEF4060BT,653 from Nexperia is a 14-stage ripple-carry binary counter/divider with integrated RC/crystal oscillator circuitry, operating across 3.0 V to 15.0 V supply, delivering Q3–Q9 and Q11–Q13 buffered outputs, and featuring asynchronous master reset (MR) for system-level timing control in clock generation and event counting applications.

For engineers reviewing the HEF4060BT,653 datasheet, HEF4060BT,653 pinout, HEF4060BT,653 application, or HEF4060BT,653 equivalent, this device supports precise frequency division in industrial timers, LED flash controllers, and microcontroller clock extension circuits where wide-voltage operation and oscillator flexibility are critical.

Technical Context

The HEF4060BT,653 implements a cascaded CMOS ripple-carry architecture with 14 flip-flops, advancing on the HIGH-to-LOW transition of the RS input. Its oscillator section accepts either external crystal (via REXT/CEXT) or RC network configurations, with RS serving as both oscillator node and external clock input - requiring REXT and CEXT to be left floating when bypassed.

Inputs include clamp diodes enabling interface to voltages exceeding VDD using current-limiting resistors. The MR pin forces all outputs LOW asynchronously, independent of clock state, and output drive strength is specified across 5 V, 10 V, and 15 V supply rails with symmetrical VOH/VOL characteristics.

FAQ

Can HEF4060BT,653 operate with a crystal oscillator?

Yes. The device supports parallel-resonant crystal oscillators via REXT and CEXT pins. A typical configuration uses a 32.768 kHz crystal with 22 pF load capacitors and a 100 kΩ bias resistor, as shown in Figure 8 of the datasheet. Crystal selection must meet the specified transconductance and load capacitance requirements to ensure reliable startup and sustained oscillation.

What happens to outputs when MR is asserted?

When MR is driven HIGH, all internal counter stages reset immediately and all buffered outputs (Q3–Q9, Q11–Q13) are forced LOW, regardless of RS clock state or previous count value. This action is asynchronous and completes within 60 ns (max) at VDD = 15 V, as verified in Table 7's tpd specification for MR → Qn.

Is external clock input compatible with the oscillator pins?

Yes. When using an external clock, RS serves as the primary clock input, and REXT and CEXT must be left unconnected (floating) to prevent interference with the clock signal path. The functional diagram (Figure 1) and Section 1 confirm that the oscillator circuit is automatically disabled when RS receives a clean external edge.

How does supply voltage affect maximum operating frequency?

Maximum RS input frequency scales with VDD: 4 MHz at 5 V, 20 MHz at 10 V, and 30 MHz at 15 V (Table 7). This relationship arises from reduced propagation delay and improved slew rate at higher supply levels, enabling faster toggle rates while maintaining setup/hold margin across all 14 stages.
