Product details
Overview
HEF4073BT-Q100 from Nexperia is a triple 3-input AND gate IC qualified to AEC-Q100 Grade 3 for automotive use, operating from -40 °C to +85 °C with supply voltage range 3.0 V to 15.0 V, CMOS low-power dissipation, and input clamp diodes enabling overvoltage-tolerant interfacing in body control modules.
For engineers reviewing the HEF4073BT-Q100 datasheet, HEF4073BT-Q100 pinout, HEF4073BT-Q100 application, or HEF4073BT-Q100 equivalent, this device supports logic-level translation, signal gating, and fault-condition arbitration in automotive powertrain and chassis subsystems where wide-VDD tolerance and high noise immunity are required.
Technical Context
The HEF4073BT-Q100 implements three independent CMOS-based AND gates with identical truth table behavior (nY = nA · nB · nC), each featuring input clamp diodes that allow safe interface to signals exceeding VDD when used with current-limiting resistors. Its static and dynamic performance is specified across the full automotive temperature range.
Propagation delays scale linearly with load capacitance (e.g., tPHL = 12 + 0.16 × CL ns at VDD = 15 V), and output drive strength varies with supply voltage (IOL = 3.6 mA min at VO = 1.5 V, VDD = 15 V). Input leakage remains ≤ ±1.0 μA at 15 V and +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple independent 3-input AND gate (nY = nA · nB · nC) |
| Supply Voltage Range | 3.0 V to 15.0 V - enables direct integration with 5 V, 12 V, and mixed-rail automotive systems |
| Operating Temperature | -40 °C to +85 °C - qualified per AEC-Q100 Grade 3 for under-hood and cabin electronics |
| Propagation Delay | 12–40 ns at VDD = 15 V, CL = 50 pF - supports reliable timing in <10 MHz combinatorial logic paths |
| Input Clamp Diodes | Integrated - permits safe interfacing to voltages > VDD using external current-limiting resistors |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation |
| Output Drive | IOL = 3.6 mA min at VO = 1.5 V, VDD = 15 V - sufficient to drive 10 pF loads with <10 ns rise/fall times |
Pinout & Package
HEF4073BT-Q100 is housed in a plastic small outline package (SO14) per SOT108-1 standard: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1–3 A) | First input of each AND gate; clamped to VSS/VDD for overvoltage protection |
| 1B, 2B, 3B | Data input (Gate 1–3 B) | Second input of each AND gate; shares same clamping and voltage rating as 1A/2A/3A |
| 1C, 2C, 3C | Data input (Gate 1–3 C) | Third input of each AND gate; enables full 3-input logic evaluation per channel |
| 1Y, 2Y, 3Y | Data output (Gate 1–3 Y) | CMOS-compatible push-pull output; drives high/low to within 50 mV of VDD/VSS under load |
| VSS | Ground reference | 0 V return path for all internal circuitry and output sinks; must be low-impedance |
| VDD | Positive supply | Primary power rail; supplies all three gates; decoupling capacitor recommended near pin 14 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 3 qualification | Validated for automotive ambient temperatures (-40 °C to +85 °C) and lifetime reliability in non-safety-critical ECUs |
| Wide VDD range (3.0–15.0 V) | Eliminates need for level shifters when interfacing with 5 V microcontrollers and 12 V sensor signals |
| Input clamp diodes | Enables direct connection to 24 V wake-up lines or LIN bus transceivers with only series resistors (no external diodes) |
| High noise immunity | Typical VIH = 11.0 V and VIL = 4.0 V at VDD = 15 V - provides >4 V noise margin in 12 V systems |
| Low static current | ID D ≤ 30 μA max at VDD = 15 V and +85 °C - supports always-on monitoring circuits with minimal quiescent drain |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC11DR | Commercial-grade (–40 °C to +85 °C), no AEC-Q100 qualification; lower VDD max (6 V); no input clamp diodes | Not suitable for direct 12 V interface or automotive production; requires external protection for overvoltage inputs | Select only for cost-sensitive non-automotive designs with stable 5 V rails and no overvoltage exposure. |
| 74LVC1G11GW | Single-gate variant; 1.65–5.5 V supply; no AEC-Q100 Grade 3; smaller XSON6 package | Requires three devices and PCB area to match functionality; unsuitable for space-constrained automotive modules needing integrated triple function | Use only when board layout favors distributed logic or when supply is strictly 3.3 V with no overvoltage risk. |
Compared with SN74HC11DR and 74LVC1G11GW, the HEF4073BT-Q100 uniquely delivers automotive qualification, 15 V tolerance with built-in clamps, and triple-gate integration in SO14 - reducing BOM count, PCB footprint, and validation effort in vehicle ECUs.

FAQ
Is HEF4073BT-Q100 pin-compatible with older HEF4073B variants?
Yes - HEF4073BT-Q100 uses the same SO14 (SOT108-1) package and identical pinout as legacy HEF4073B devices, including matching VDD (pin 14), VSS (pin 7), and gate I/O assignments. No PCB redesign is needed for drop-in replacement in existing automotive designs.
Can HEF4073BT-Q100 safely interface with 24 V wake-up signals?
Yes - its integrated input clamp diodes allow direct connection to 24 V lines when used with appropriate current-limiting resistors (e.g., 10 kΩ), limiting input current to <10 mA per pin as specified in the absolute maximum ratings, without external protection components.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50 pF load capacitance per gate, with propagation delay and transition time data provided for CL = 50 pF. Driving >50 pF may increase delay and reduce edge speed but remains functional; for >100 pF, consider buffering or reducing trace length.
Does HEF4073BT-Q100 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs should be tied to VDD or VSS to prevent floating states and increased power consumption, but no external resistors are required due to CMOS input structure. Floating inputs cause undefined output states and elevated IDD, so hard-wiring is mandatory per design guidelines.
