STMicroelectronics HCF4013M013TR

Overview

HCF4013M013TR from STMicroelectronics is a dual D-type flip-flop IC with independent set/reset control, static operation (state retention at any clock level), 16 MHz typical toggle rate at 10 V, ±100 nA max input leakage at 18 V, and SO14 packaging. It serves as a synchronous storage element in digital logic systems requiring edge-triggered data latching, such as shift registers and binary counters.

For engineers reviewing the HCF4013M013TR datasheet, HCF4013M013TR pinout, HCF4013M013TR application, or HCF4013M013TR equivalent, key selection criteria include supply voltage range (3–20 V), propagation delay (45–300 ns depending on VDD), quiescent current (0.02–600 μA), and automotive-grade temperature tolerance (–55 °C to +125 °C).

Technical Context

The HCF4013M013TR implements two identical, electrically isolated CMOS D-type flip-flops, each with asynchronous active-high SET and RESET inputs, a positive-edge-triggered CLOCK input, and complementary Q/Q̅ outputs. Data transfer occurs only on the rising edge of CLOCK, while SET/RESET override clock timing and force immediate output states.

It operates across a wide VDD range (3–20 V) with symmetrical output drive (±1.15 mA IOH/IOL at 5 V), guaranteed noise margins (1 V min at 5 V), and ESD protection rated at 2 kV HBM. Its static core retains state indefinitely without clock activity, enabling low-power memory hold functionality.

FAQ

What is the maximum clock frequency supported by the HCF4013M013TR?

The HCF4013M013TR supports a maximum clock toggle rate of 16 MHz (typical) at VDD = 10 V, 12 MHz (typical) at VDD = 15 V, and 7 MHz (typical) at VDD = 5 V, as specified in Table 7 of ST's DocID2023 Rev 4. These values assume CL = 50 pF and Tamb = 25 °C; actual usable frequency decreases with higher capacitive load or elevated temperature.

Can the HCF4013M013TR operate at 3.3 V supply voltage?

Yes - the HCF4013M013TR is fully specified down to VDD = 3 V per Table 5 (Recommended Operating Conditions). At 3.3 V, propagation delays increase (e.g., tPLH/tPHL ≈ 500–600 ns), and output drive weakens (IOL ≈ 0.2 mA), but logic thresholds remain valid and static operation is maintained. No external level shifting is needed for 3.3 V CMOS interfacing.

Does the HCF4013M013TR have built-in ESD protection?

Yes - the device includes integrated ESD protection networks on all inputs, with validated ratings of 2 kV (HBM), 200 V (MM), and 1 kV (CDM) per Section 1 of the datasheet. This meets standard handling requirements for automated assembly and field service, though external TVS diodes are still recommended for I/O lines exposed to connectors or cables.

How does the asynchronous SET/RESET functionality interact with the clock signal?

SET and RESET inputs are asynchronous and dominant: a high level on either forces immediate output transition (Q = 1 or Q = 0) regardless of CLOCK state or timing. They override all clock-triggered behavior and require no setup/hold time relative to CLOCK. Once released, the flip-flop resumes normal edge-triggered operation on the next rising clock edge.
