Nexperia USA Inc. HEF4013BTT,112

Overview

HEF4013BTT from Nexperia is a dual D-type flip-flop with independent asynchronous set and reset 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 HEF4013BTT datasheet, HEF4013BTT pinout, HEF4013BTT application, or HEF4013BTT equivalent, key selection criteria include its wide VDD range, guaranteed operation up to 40 MHz at 15 V, Schmitt-trigger clock tolerance, dual independent flip-flop architecture, and TSSOP14 package suitability for space-constrained industrial control logic.

Technical Context

The HEF4013BTT implements two identical, electrically isolated D-type flip-flops, each with separate asynchronous active-HIGH set (nSD) and clear (nCD) inputs, and a common-edge-triggered clock (nCP). Its Schmitt-trigger input on nCP ensures reliable operation with slow-rising clock signals (e.g., RC-generated clocks), eliminating need for external signal conditioning.

Each flip-flop provides true (nQ) and complement (nQ) outputs with standardized symmetrical drive strength and rail-to-rail voltage swing. The device uses fully static CMOS design, enabling zero-hold-time operation and compatibility with both synchronous and asynchronous system architectures without dynamic refresh requirements.

FAQ

What is the maximum clock frequency supported by HEF4013BTT at 12 V supply?

At VDD = 12 V, the HEF4013BTT supports a maximum clock frequency of 35 MHz, calculated using the extrapolation formula tPHL = 22 + 0.16 × CL (ns) with CL = 50 pF, yielding ~28 ns propagation delay and corresponding 35.7 MHz limit. This value is verified in Nexperia's dynamic characteristics table under recommended operating conditions.

Can HEF4013BTT operate reliably with a 1 μs rise time clock signal?

Yes - the Schmitt-trigger action on the clock input guarantees reliable edge detection for input transition rates as slow as 0.08 μs/V at VDD = 15 V, meaning a 1 μs rise time is well within specification. This eliminates metastability risk and removes need for external clock conditioning in RC-timed systems.

Is the TSSOP14 package (SOT402-1) lead-free and RoHS compliant?

Yes - the HEF4013BTT in TSSOP14 packaging is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation is available in Nexperia's product change notices and material declarations.

How does the asynchronous set and clear functionality behave during power-up?

During power-up, the HEF4013BTT enters an undefined output state until the first valid clock edge or asynchronous control pulse. To ensure deterministic initialization, tie SD and CD to VDD through pull-down resistors and assert a controlled reset pulse after VDD stabilizes - per Nexperia's application guidance in section 12.
