Nexperia USA Inc. HEF4013BT,653

Overview

HEF4013BT,653 from Nexperia is a dual D-type flip-flop with independent asynchronous set and clear inputs, positive-edge clock triggering, and Schmitt-trigger clock inputs for robust timing in noisy environments. It operates across 3.0 V to 15.0 V supply, supports -40 °C to +125 °C ambient range, and delivers symmetrical CMOS output drive (±4.2 mA at 15 V). It is used in binary ripple counters, shift registers, and toggle configurations requiring deterministic edge-triggered storage.

For engineers reviewing the HEF4013BT,653 datasheet, HEF4013BT,653 pinout, HEF4013BT,653 application, or HEF4013BT,653 equivalent, key selection considerations include its wide VDD range, guaranteed operation up to +125 °C, Schmitt-trigger clock tolerance, dual independent flip-flop architecture, and SO14 (SOT108-1) package compatibility with legacy 4000-series logic layouts.

Technical Context

The HEF4013BT implements two identical, electrically isolated D-type flip-flops, each with separate asynchronous active-HIGH set (SD) and clear (CD) inputs, and a common-edge-triggered clock (CP). Its Schmitt-trigger input on CP enables reliable operation with slow-rising or noisy clock signals without external conditioning.

Each flip-flop follows strict synchronous D-latch behavior on the rising edge of CP while maintaining static retention between edges. The function table confirms deterministic outputs under all valid control combinations, including priority of asynchronous SD/CD over clocked data, with no metastability guarantees beyond specified setup/hold times (e.g., tsu = 15 ns, th = 0 ns at 15 V).

FAQ

Can HEF4013BT,653 operate reliably with a 12 V supply and 100 pF capacitive load?

Yes. At 12 V, the HEF4013BT,653 maintains tPHL/tPLH ≤ 35 ns (typical) and VOH ≥ 11.95 V with |IOL| ≥ 3.4 mA, fully supporting 100 pF loads per output. Derating curves confirm Ptot remains within 500 mW limit up to +125 °C with appropriate PCB copper area.

What is the minimum pulse width required on the SD or CD inputs for reliable asynchronous assertion?

The minimum pulse width (tW) for SD or CD is 10 ns at 15 V, 25 ns at 10 V, and 40 ns at 5 V, as verified in Table 7. These values ensure internal latch nodes fully settle before clock sampling, preventing metastability-induced output glitches.

Does the Schmitt-trigger action apply to all inputs or only the clock?

Schmitt-trigger action applies exclusively to the clock inputs (1CP and 2CP), as confirmed in Section 1 General Description. Data (D), set (SD), and clear (CD) inputs use standard CMOS thresholds (VIH = 11.0 V, VIL = 4.0 V at 15 V) without hysteresis.

Is the SO14 package (SOT108-1) of HEF4013BT,653 RoHS compliant and lead-free?

Yes. The HEF4013BT,653 uses a lead-free, RoHS-compliant SO14 package (SOT108-1) with matte tin plating, meeting Nexperia's standard environmental specifications per EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3.
