Product details
Overview
HEF4014BT-Q100 from Nexperia is an AEC-Q100 Grade 3 qualified 8-bit static shift register with synchronous parallel enable, operating from 3.0 V to 15.0 V supply, featuring clamp diodes for overvoltage-tolerant input interfacing and LOW-to-HIGH edge-triggered clock (CP). It functions as a parallel-to-serial converter in automotive body control modules requiring robust serial data queuing under wide temperature (-40 °C to +85 °C) and voltage conditions.
For engineers reviewing the HEF4014BT-Q100 datasheet, HEF4014BT-Q100 pinout, HEF4014BT-Q100 application, or HEF4014BT-Q100 equivalent, key selection considerations include its 8-bit synchronous parallel load capability, CMOS low-power operation at 15 V, AEC-Q100 qualification, and SO16 package compatibility with legacy 4000-series logic designs.
Technical Context
The HEF4014BT-Q100 implements a fully static 8-bit shift register with dual-mode operation: serial shift-in via DS on CP rising edge, or parallel load of D0–D7 when PE is HIGH. Its internal structure uses eight identical D-type flip-flops with common clock (CP) and asynchronous reset not present - enabling deterministic timing without race conditions.
Input clamping diodes allow direct interface to signals exceeding VDD (e.g., 12 V automotive buses), while symmetrical output drive (±3.6 mA at 15 V) supports driving capacitive loads up to 50 pF with guaranteed tPLH/tPHL ≤ 80 ns and tt ≤ 40 ns. Propagation delay scales predictably with load capacitance per published extrapolation formulas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit synchronous static shift register with parallel enable (PE) |
| Supply Voltage Range | 3.0 V to 15.0 V - enables direct use across 5 V, 10 V, and 15 V automotive subsystems without level shifting |
| Operating Temperature | -40 °C to +85 °C - qualified per AEC-Q100 Grade 3 for under-hood and cabin electronics |
| Max Clock Frequency | 40 MHz at VDD = 15 V - supports high-speed serial data transfer in infotainment or gateway applications |
| Output Drive Strength | ±3.6 mA at VDD = 15 V - sufficient to drive multiple CMOS inputs or moderate PCB traces without buffering |
| Input Clamp Protection | Integrated diodes allow safe interface to signals up to VDD + 0.5 V - eliminates need for external current-limiting resistors in many cases |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets automotive ESD robustness requirements per JS-001/JS-002 |
Pinout & Package
HEF4014BT-Q100 is housed in a plastic small outline package (SO16), SOT109-1 variant, with 16 leads, 3.9 mm body width, and standard 1.27 mm lead pitch - compatible with automated SMT assembly and legacy 4000-series footprint layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4–7, 13–15 | D0–D7 | Parallel data inputs - loaded simultaneously into register when PE = HIGH and CP rises |
| 2, 3, 12 | Q5–Q7 | Serial output bits - Q7 is MSB of shifted-out data stream; outputs retain state during hold cycles |
| 8 | VSS | Ground reference - must be low-impedance connection to minimize switching noise coupling |
| 9 | PE | Parallel enable - HIGH enables parallel load; LOW enables serial shift mode on CP edges |
| 10 | CP | Clock input - LOW-to-HIGH edge triggers both parallel load and serial shift operations |
| 11 | DS | Serial data input - fed into D0 position on each CP rising edge during serial shift mode |
| 16 | VDD | Positive supply - supports wide-range operation; internal clamp diodes referenced to this rail |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous parallel enable | Enables deterministic loading of all 8 bits on single CP edge - critical for synchronized sensor data capture |
| Clamp diode-equipped inputs | Permits direct connection to 12 V automotive signals using only series resistors - reduces BOM count and layout area |
| Wide VDD range (3–15 V) | Eliminates need for separate voltage regulators in mixed-supply systems - simplifies power architecture |
| AEC-Q100 Grade 3 qualification | Validated for automotive ambient temperatures and reliability stress - reduces qualification effort for Tier 1 suppliers |
| CMOS low-power static operation | IDD ≤ 600 μA at 15 V and +85 °C - enables always-on functionality in battery-sensitive modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4014BE | Non-automotive, no AEC-Q100 qualification; max VDD = 18 V but only rated to +70 °C | Limited to commercial/industrial environments; lacks automotive thermal and reliability validation | Select only for non-automotive prototypes or cost-sensitive non-safety systems where qualification is waived |
| SN74HC165PWR | 3.3 V/5 V only; no 10 V/15 V support; no input clamp diodes; different pinout (Q7/Q0 reversed) | Requires level-shifting for 12 V inputs; incompatible with existing SO16 4000-series layouts | Prefer for new 3.3 V designs needing higher speed (100 MHz fclk) but unsuitable for drop-in replacement or 12 V interfaces |
Compared with CD4014BE and SN74HC165PWR, the HEF4014BT-Q100 uniquely combines AEC-Q100 Grade 3 qualification, 3–15 V operation, integrated input clamps, and SO16 pin compatibility - making it the sole option for drop-in upgrades of legacy automotive 4000-series shift register designs requiring production-grade reliability.

FAQ
What is the maximum clock frequency supported at 5 V supply?
At VDD = 5 V, the HEF4014BT-Q100 supports a maximum clock frequency of 13 MHz, derived from the dynamic characteristics table where fclk(max) = 13 MHz (min) and 26 MHz (typ) - verified under CL = 50 pF load and Tamb = 25 °C per Table 7.
Does the device support asynchronous reset or clear functionality?
No, the HEF4014BT-Q100 does not include an asynchronous reset (MR or CLR) input. Its operation relies solely on synchronous control via CP and PE; clearing the register requires either serial shifting out all bits or parallel loading zeros via D0–D7 with PE HIGH.
Can DS and D0–D7 be driven simultaneously without conflict?
Yes - during parallel load mode (PE = HIGH), DS is ignored; during serial shift mode (PE = LOW), D0–D7 inputs are disabled and have no effect. This isolation prevents bus contention and ensures deterministic behavior regardless of simultaneous signal presence.
Is the SO16 package RoHS-compliant and lead-free?
Yes, the HEF4014BT-Q100 in SOT109-1 (SO16) packaging is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and Nexperia's environmental policy - confirmed in the product change notification associated with Rev. 4 (August 2024).
