NXP Semiconductors HEF4013BP,652

Overview

HEF4013BP,652 from Nexperia is a dual D-type flip-flop with independent asynchronous set and clear inputs, positive-edge-triggered clock, and Schmitt-trigger clock input for tolerance to slow signal edges. 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 in a 14-lead SO package. It is used in binary counters, shift registers, and toggle configurations requiring deterministic edge-triggered storage.

For engineers reviewing the HEF4013BP,652 datasheet, HEF4013BP,652 pinout, HEF4013BP,652 application, or HEF4013BP,652 equivalent, key selection considerations include its dual independent flip-flop architecture, 15 V absolute maximum supply rating, Schmitt-trigger clock input enabling robust timing in noisy environments, guaranteed operation at 125 °C, and compatibility with legacy 4000-series logic voltage scaling.

Technical Context

The HEF4013BP,652 implements two identical, electrically isolated D-type flip-flops sharing no internal logic-each with dedicated data (D), clock (CP), set-direct (SD), clear-direct (CD), true (Q), and complement (Q̅) terminals. Its Schmitt-trigger clock input provides hysteresis (typical 1.5 V at VDD = 5 V), eliminating need for external signal conditioning on slow-rising clocks.

Each flip-flop responds only to LOW-to-HIGH transitions on its CP input, while SD and CD are active-HIGH asynchronous controls overriding clock and data states. The device uses standard CMOS silicon process, delivering static operation with zero DC current draw in steady state and input leakage below ±1.0 μA at 125 °C.

FAQ

What is the maximum clock frequency supported by the HEF4013BP,652?

The HEF4013BP,652 supports up to 40 MHz maximum clock frequency at VDD = 15 V and Tamb = 25 °C, as specified in Table 7 of the datasheet. At 125 °C, the practical limit reduces due to increased propagation delay; design margin should include derating to ~25 MHz for full-temperature operation. The HEF4013BP,652 achieves this using optimized CMOS gate sizing and Schmitt-trigger input buffering to maintain edge integrity.

Does the HEF4013BP,652 require external pull-up or pull-down resistors on its inputs?

No, the HEF4013BP,652 does not require external pull-up or pull-down resistors on its inputs. Its CMOS inputs have negligible leakage (<±1.0 μA at 125 °C), and the Schmitt-trigger clock input provides built-in hysteresis. Unused inputs should be tied to VDD or VSS to prevent floating states-direct connection suffices without resistors. This simplifies board layout and reduces BOM count for the HEF4013BP,652.

Can the HEF4013BP,652 operate reliably at 15 V supply with full functionality?

Yes, the HEF4013BP,652 is fully characterized and guaranteed to operate at 15 V supply across its entire -40 °C to +125 °C temperature range. Static and dynamic parameters-including VOH, VOL, propagation delay, and power dissipation-are explicitly rated at 15 V in Tables 5, 6, and 7. The HEF4013BP,652's 18 V absolute maximum rating provides headroom for transient spikes, confirming robust 15 V operation.

How does the Schmitt-trigger input on the HEF4013BP,652 improve system reliability?

The Schmitt-trigger input on the HEF4013BP,652 provides ~1.5 V hysteresis at 5 V supply, rejecting noise and preventing multiple clock triggers from slow or noisy edges. This eliminates false triggering in applications like mechanical switch debouncing, RC oscillator interfaces, or long PCB traces-ensuring one clean state transition per intended edge. The HEF4013BP,652 thus improves timing determinism without external components.

Is the HEF4013BP,652 pin-compatible with older HEF4013B variants?

Yes, the HEF4013BP,652 is fully pin-compatible with legacy HEF4013B devices in SO14 (SOT108-1) packaging, including identical pin numbering, function mapping, and mechanical footprint. It maintains backward compatibility with existing PCB layouts and schematics while incorporating updated ESD protection and tighter parametric tolerances per Rev. 12 datasheet. No redesign is needed when upgrading to HEF4013BP,652.
