Product details
Overview
HEF4073BT,653 from Nexperia is a triple 3-input CMOS AND gate IC operating from 3.0 V to 15.0 V supply, featuring input clamp diodes for overvoltage-tolerant interfacing, ±10 mA output drive capability at 5 V, and guaranteed operation from -40 °C to +85 °C. It performs basic combinational logic in digital control subsystems, power sequencing circuits, and enable gating for industrial microcontroller peripherals.
For engineers reviewing the HEF4073BT,653 datasheet, HEF4073BT,653 pinout, HEF4073BT,653 application, or HEF4073BT,653 equivalent, key selection criteria include supply voltage range compatibility (3–15 V), propagation delay vs. load capacitance (e.g., 23 ns typ. @ 5 V, CL = 50 pF), input clamping diode support for >VCC interface, and SO14 package thermal and layout constraints.
Technical Context
The HEF4073BT,653 implements three independent AND gates using standard CMOS logic architecture with buffered outputs and input clamp diodes tied to VDD and VSS. Each gate accepts three logic-level inputs and produces a single active-HIGH output, with propagation delays defined per VDD and load capacitance (e.g., tPHL = 12 ns typ. @ 15 V, CL = 50 pF).
It operates within JEDEC JESD13-B compliance and supports static and dynamic operation across its full rated temperature range (-40 °C to +85 °C), with input leakage current ≤ ±1.0 μA at 15 V and output transition times as low as 6 ns (typ.) under light capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - Enables direct use with legacy 5 V, 10 V, and 12 V logic rails without level translation. |
| Propagation Delay (tPHL) | 12 ns (typ.) @ VDD = 15 V, CL = 50 pF - Determines maximum clock/data rate in synchronous gating applications. |
| Output Drive (IOL) | 3.6 mA (min.) @ VDD = 15 V, VO = 1.5 V - Sufficient to directly drive TTL inputs or small capacitive loads (≤50 pF). |
| Input Clamp Diodes | Present on all inputs - Allows safe interface to signals up to VDD + 0.5 V using external current-limiting resistors. |
| Operating Temperature | -40 °C to +85 °C - Qualified for industrial ambient environments without derating. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces need for external ESD protection in board-level designs. |
Pinout & Package
HEF4073BT,653 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 surface-mount terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1–3 A) | First input of each 3-input AND gate; clamped to VDD/VSS for overvoltage tolerance. |
| 1B, 2B, 3B | Data input (Gate 1–3 B) | Second input of each gate; electrically identical to 1A/2A/3A pins. |
| 1C, 2C, 3C | Data input (Gate 1–3 C) | Third input of each gate; shares same clamping and voltage rating as other inputs. |
| 1Y, 2Y, 3Y | Data output (Gate 1–3 Y) | Active-HIGH AND result; capable of sourcing/sinking ≥3.6 mA at 15 V. |
| VSS | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for noise immunity. |
| VDD | Positive supply | Primary power rail (3–15 V); decoupling capacitor required near pin 14 for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | Operates across 3.0 V to 15.0 V - eliminates need for separate voltage regulators in mixed-rail systems. |
| CMOS low power dissipation | IDDTyp = 4.0 μA @ 15 V, 25 °C - enables battery-powered or energy-sensitive logic gating without thermal concern. |
| High noise immunity | VIL = 4.0 V, VIH = 11.0 V @ VDD = 15 V - provides >3.5 V noise margin in noisy industrial environments. |
| Input clamp diodes | Integrated anode-to-VDD and cathode-to-VSS diodes - permits robust interfacing to external controllers exceeding VDD by ≤0.5 V. |
Applications
| Industrial Power Sequencing | Digital Enable Gating |
|---|---|
Use Scenario: Coordinating startup order of multiple DC-DC converters in programmable power supplies. IC Role / Device Role / Timing Role: Logic-level AND gate enabling downstream regulator only when all upstream rails are valid and stable. Use Value: Ensures fault-free power-up by requiring simultaneous presence of three status signals before activation. | Use Scenario: Controlling peripheral enable lines in microcontroller-based data acquisition systems. IC Role / Device Role / Timing Role: Combining MCU GPIO, watchdog OK flag, and system reset state into a single gated enable signal. Use Value: Prevents peripheral operation during unsafe states (e.g., reset asserted or watchdog timeout). |
| Legacy System Bus Control | LED Driver Logic Interface |
Use Scenario: Generating chip-select signals for parallel memory or peripheral ICs in retro-computing or test equipment. IC Role / Device Role / Timing Role: AND-ing address decode bits and master enable to generate precise memory window selection. Use Value: Provides deterministic, glitch-free chip select with sub-25 ns propagation at 5 V for reliable bus timing. | Use Scenario: Interfacing microcontroller PWM outputs to high-current LED drivers requiring multi-signal validation. IC Role / Device Role / Timing Role: Validating dimming command, thermal OK, and overcurrent clear before enabling LED output stage. Use Value: Adds hardware-level safety interlock that remains functional even if firmware fails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4073BE | Same logic function and pinout; wider temp range (-55 °C to +125 °C); higher max VDD (18 V); no documented clamp diodes. | Preferred for extended temperature or higher-voltage (>15 V) systems where input overvoltage protection is handled externally. | Select CD4073BE when operating beyond +85 °C or above 15 V, and external clamping is acceptable. |
| 74HC11D,652 | Same SO14 pinout; 2–6 V supply range; faster propagation (~10 ns @ 5 V); no input clamp diodes; lower drive (±4 mA). | Suitable for 3.3 V/5 V high-speed logic but incompatible with >6 V rails or overvoltage-tolerant interfaces. | Choose 74HC11D,652 for speed-critical 5 V-only designs where input voltage stays within VDD. |
Compared with CD4073BE and 74HC11D,652, the HEF4073BT,653 uniquely balances industrial temperature operation, wide 3–15 V supply support, and integrated input clamping-making it optimal for mixed-voltage industrial control where robustness and flexibility outweigh raw speed.

FAQ
What is the maximum recommended supply voltage for HEF4073BT,653?
The absolute maximum supply voltage is +18 V, but the recommended operating range is 3.0 V to 15.0 V per the datasheet. Operation above 15.0 V voids guaranteed performance and may accelerate long-term reliability degradation, even if within absolute limits.
Does HEF4073BT,653 support 3.3 V logic levels?
Yes - at VDD = 3.3 V, VIH is specified as ≥2.1 V and VIL ≤1.2 V, providing adequate margin for standard 3.3 V CMOS logic. However, propagation delay increases (e.g., ~45 ns typ. @ CL = 50 pF), and output drive reduces proportionally.
Can HEF4073BT,653 inputs safely accept 24 V signals?
No - input voltage must remain between -0.5 V and VDD + 0.5 V. While clamp diodes allow limited overvoltage (e.g., 15.5 V max at VDD = 15 V), 24 V exceeds this and requires external current-limiting resistors plus series diode clamping to VDD/VSS to prevent damage.
Is HEF4073BT,653 pin-compatible with older HEF4073B variants?
Yes - HEF4073BT,653 uses the same SO14 (SOT108-1) package and identical pinout as all HEF4073B-series devices, including HEF4073BP (DIP) and HEF4073BD (SO14). Functional behavior and electrical specs are consistent across the B-suffix revision family.
