Product details
Overview
HEF4104BT/S400118 from Nexperia is a quad low-to-high voltage translator IC with complementary 3-state outputs (Bn and Bn), designed for bidirectional level shifting between two independent supply domains (VDD(A) and VDD(B)). It supports 3.0 V to 15.0 V operation on both sides, delivers propagation delays as low as 57 ns at 15 V, and features output enable (OE) control with high-impedance OFF-state. It is used in mixed-voltage digital systems such as industrial I/O interfaces and legacy bus bridging.
For engineers reviewing the HEF4104BT/S400118 datasheet, HEF4104BT/S400118 pinout, HEF4104BT/S400118 application, or HEF4104BT/S400118 equivalent, key selection criteria include dual-supply voltage range compatibility, guaranteed 3-state timing (tPHZ/tPLZ ≤ 120 ns), input clamp diode support for overvoltage-tolerant interfacing, and SO16 package thermal performance under -40 °C to +85 °C ambient conditions.
Technical Context
The HEF4104BT/S400118 implements four independent CMOS-based level-shifting channels, each with true complementary outputs (Bn and Bn) and shared output enable (OE). Its architecture isolates VDD(A) and VDD(B) domains, allowing translation from lower-voltage logic (e.g., 3.3 V or 5 V) to higher-voltage logic (up to 15 V) while maintaining rail-to-rail output swing and static noise immunity.
Input clamping diodes enable safe interface to voltages exceeding VDD(A), permitting use of current-limiting resistors for overvoltage protection. The device operates fully statically and complies with JEDEC JESD13-B, with HBM ESD rating >2000 V and CDM >1000 V - critical for robustness in industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VDD(A): 3.0–15.0 V; VDD(B): ≥ VDD(A), up to +18 V absolute max - enables flexible domain separation and overvoltage-safe design |
| Propagation Delay (tPHL/tPLH) | 65 ns max at VDD = 15 V, CL = 50 pF - ensures timing predictability in high-speed mixed-voltage data paths |
| Output Enable Timing (tPHZ/tPLZ) | 120 ns max at VDD = 15 V - guarantees fast, deterministic bus release for time-critical arbitration |
| Input Voltage Thresholds | VIH = 11.0 V min, VIL = 4.0 V max at VDD(A) = 15 V - provides wide noise margin for TTL/CMOS-compatible signaling |
| Output Drive Strength | IOL = 3.6 mA min, IOH = −3.6 mA min at VDD(B) = 15 V - supports direct drive of 50-pF loads without external buffers |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded systems and factory automation equipment |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets robustness requirements for handling and board-level integration |
Pinout & Package
HEF4104BT/S400118 is housed in a plastic small outline package (SO16) per SOT109-1 standard: 16-pin, 3.9 mm body width, 1.27 mm pitch, with gull-wing leads and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD(B) | Positive supply for output domain B - must be ≥ VDD(A); sets output logic high level and drive capability |
| 2,7,9,14 | B0–B3 | True (non-inverted) complementary outputs - active HIGH when OE = HIGH; driven to VDD(B) or VSS |
| 3,6,10,13 | B0–B3 | Inverted complementary outputs - logic inverse of B0–B3; enables differential signaling or active-low bus control |
| 4,5,11,12 | A0–A3 | Data inputs referenced to VDD(A) - accept 0 V to VDD(A); clamp diodes allow safe overvoltage tolerance |
| 8 | VSS | Common ground reference for both domains - mandatory 0 V connection for proper biasing and noise rejection |
| 15 | OE | Active-HIGH output enable - LOW forces all Bn/Bn outputs into high-impedance state for bus sharing |
| 16 | VDD(A) | Positive supply for input domain A - defines input logic thresholds and powers internal level-shift circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VDD(A) and VDD(B) operate at different voltages (e.g., 5 V ↔ 12 V), enabling seamless inter-domain communication without external regulators |
| Complementary 3-state outputs | Each channel provides matched Bn and Bn signals with simultaneous high-impedance disable - supports wired-OR buses and bidirectional data lanes |
| Input clamp diodes | Allow safe interface to input voltages exceeding VDD(A) using series current-limiting resistors - eliminates need for external protection components |
| JEDEC JESD13-B compliance | Ensures interoperability with industry-standard logic families and predictable timing behavior across temperature and voltage corners |
| Wide temperature range | Specified from −40 °C to +85 °C - validated for continuous operation in uncontrolled industrial enclosures and outdoor control cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-to-high voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH4T245PWR | 3.3 V–5 V only; auto-direction sensing; no complementary outputs; smaller 16-pin TSSOP package | Optimized for high-speed bidirectional data buses (e.g., PCIe sideband, USB PHY), not high-voltage translation | Select when translating between adjacent low-voltage domains with direction auto-detection needed; not suitable for >5 V B-side operation. |
| TXS0104EPRJR | Open-drain outputs; 1.65 V–3.6 V A-side, 2.3 V–5.5 V B-side; no VDD(B) > VDD(A) support; integrated auto-bidirectional control | Targeted at I²C, SMBus, and low-power GPIO expansion - lacks complementary outputs and high-voltage drive | Choose for ultra-low-power, open-drain bus translation where complementary outputs and >5 V operation are unnecessary. |
Compared with SN74AVCH4T245PWR and TXS0104EPRJR, the HEF4104BT/S400118 uniquely supports asymmetric high-voltage translation (e.g., 5 V → 15 V) with true complementary outputs and robust industrial temperature/ESD specs - making it irreplaceable in legacy system upgrades and high-reliability sensor interfacing.

FAQ
What is the maximum allowable voltage difference between VDD(A) and VDD(B) for HEF4104BT/S400118?
The HEF4104BT/S400118 requires VDD(B) ≥ VDD(A), with no fixed maximum delta specified. Absolute maximum ratings permit VDD(A) up to +18 V and VDD(B) up to +18 V independently, but the functional specification mandates VDD(B) ≥ VDD(A). For reliable operation, maintain VDD(B) within 0.5 V to 15 V above VDD(A) - e.g., 5 V on A-side and 12 V on B-side is valid, while 15 V on A-side and 5 V on B-side violates the architecture and will cause malfunction. Always refer to Figure 4 (operating area) in the datasheet.
Can HEF4104BT/S400118 translate signals from a 3.3 V microcontroller to a 15 V display driver?
Yes, the HEF4104BT/S400118 is explicitly rated for this use case: VDD(A) = 3.3 V and VDD(B) = 15 V satisfies both the recommended operating conditions (VDD(A) ≥ 3.0 V, VDD(B) ≤ 15.0 V) and the functional requirement VDD(B) ≥ VDD(A). Input thresholds scale with VDD(A), so 3.3 V logic levels meet VIH/VIL margins, and outputs swing rail-to-rail from 0 V to 15 V. The device's 15 V parametric rating and 100 mA total power dissipation ensure stable operation under these conditions.
Does HEF4104BT/S400118 support hot-swap or live insertion into a powered system?
No, the HEF4104BT/S400118 is not hot-swap rated. Its absolute maximum ratings do not cover powered insertion scenarios, and the input clamp diodes are intended for transient overvoltage protection - not sustained back-powering. Applying VDD(A) or VDD(B) before establishing VSS, or asserting OE before supplies stabilize, may cause latch-up or excessive current. System-level hot-swap requires external sequencing circuitry, current limiting, and dedicated hot-swap controllers - the HEF4104BT/S400118 itself provides no built-in hot-swap protection.
How does the complementary output structure (Bn and Bn) benefit system design with HEF4104BT/S400118?
The complementary outputs (e.g., B0 and B0) of the HEF4104BT/S400118 provide true logic inversion without external inverters - enabling differential signaling, active-low bus control, or wired-OR configurations. This reduces component count and propagation delay skew in timing-critical paths. For example, driving a 74HC138 decoder's active-low enable and select inputs simultaneously from one A0 input eliminates gate delays and layout mismatches, improving setup/hold timing margins in industrial multiplexed I/O systems.
Is HEF4104BT/S400118 suitable for automotive applications?
No, HEF4104BT/S400118 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 14 and confirms no AEC-Q100 qualification or automotive testing. While it operates from −40 °C to +85 °C - overlapping with some automotive ambient ranges - it lacks automotive-specific stress testing, failure mode analysis, PPAP documentation, and zero-defect manufacturing controls. Use only in industrial, commercial, or consumer equipment; for automotive designs, select Nexperia's automotive-grade alternatives like the 74LVC4245ABQ.
