Product details
Overview
HEF4050BP,652 from Nexperia is a hex non-inverting CMOS buffer IC with overvoltage-tolerant inputs rated to 15.0 V, operating across 3.0 V to 15.0 V supply, specified from −40 °C to +85 °C, and packaged in SO16 (SOT109-1). It enables HIGH-to-LOW level shifting between LOCMOS and TTL/DTL logic families.
For engineers reviewing the HEF4050BP,652 datasheet, HEF4050BP,652 pinout, HEF4050BP,652 application, or HEF4050BP,652 equivalent, this device is selected for robust level translation, TTL load driving, and static CMOS interfacing where input overvoltage resilience and wide VDD range are critical.
Technical Context
The HEF4050BP,652 implements six independent non-inverting buffer stages with symmetrical output drive capability and fully static operation. Its input protection circuitry allows safe operation with input voltages up to 15.0 V regardless of VDD, enabling direct interface with higher-voltage logic domains.
Each buffer delivers guaranteed fan-out of 2 into standard TTL, 9 into 74LS, and 16 into 74L loads. Propagation delays scale inversely with supply voltage: tPHL = 12 ns + (0.05 ns/pF)CL at VDD = 15 V, and tPLH = 12 ns + (0.16 ns/pF)CL under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - supports mixed-voltage system interfacing without external level shifters |
| Input Voltage Tolerance | −0.5 V to +18 V - enables overvoltage-tolerant operation beyond VDD, critical for HIGH-to-LOW translation |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial ambient environments |
| Propagation Delay (VDD = 15 V) | tPHL/tPLH ≤ 30 ns / 40 ns - ensures timing predictability in high-speed digital control paths |
| Output Drive (VDD = 15 V) | IOL ≥ 16.0 mA - drives two standard TTL loads directly per output |
| Input Leakage Current | ±1.0 μA max at 15 V - minimizes loading on upstream signal sources |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 for robust handling in manufacturing |
Pinout & Package
HEF4050BP,652 is housed in a plastic small outline package (SO16), SOT109-1 variant, with 16 leads and 3.9 mm body width. Pin 1 is marked by index notch; pins 13 and 16 are not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply | Primary CMOS supply rail; must be decoupled locally for noise immunity |
| 1Y–6Y (Pins 2,4,6,10,12,15) | Buffer outputs | Non-inverted logic outputs; each capable of sinking ≥16 mA at VDD = 15 V |
| 1A–6A (Pins 3,5,7,9,11,14) | Buffer inputs | Overvoltage-tolerant inputs accepting up to +15 V independent of VDD |
| VSS (Pin 8) | Ground reference | Logic ground return; must be low-impedance path to minimize switching noise |
| n.c. (Pins 13,16) | No connection | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Wide VDD range (3–15 V) | Enables single-bus compatibility across legacy 5 V, modern 10 V, and high-voltage 15 V logic domains |
| Overvoltage-tolerant inputs | Accepts 15 V inputs while powered from as low as 3 V - eliminates need for external clamping diodes |
| Standardized symmetrical output | Matched rise/fall times and drive strength simplify timing analysis in synchronous interfaces |
| JEDEC JESD13-B compliance | Ensures interoperability with industry-standard CMOS logic families and test equipment |
| High noise immunity | Guaranteed VIL ≤ 4.0 V and VIH ≥ 11.0 V at VDD = 15 V - rejects transient coupling in noisy industrial settings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4050BE | Same logic function but lower ESD rating (HBM > 2 kV not guaranteed); no JEDEC JESD13-B compliance stated | Not qualified for high-noise industrial environments requiring certified ESD robustness | Select HEF4050BP,652 when HBM > 2000 V and JEDEC compliance are mandatory |
| 74HC4050D | Higher speed (tP ≈ 8 ns at 5 V) but limited VDD range (2–6 V); inputs not overvoltage tolerant | Unsuitable for HIGH-to-LOW translation above 6 V or mixed-supply interfacing | Select HEF4050BP,652 when >6 V operation or input overvoltage tolerance is required |
Compared with CD4050BE and 74HC4050D, HEF4050BP,652 uniquely combines 15 V input tolerance, 3–15 V supply flexibility, and certified industrial-grade ESD protection - making it the only option for robust level translation in extended-voltage industrial systems.

FAQ
What is the maximum input voltage rating for HEF4050BP,652?
The HEF4050BP,652 features overvoltage-tolerant inputs rated to +15.0 V absolute maximum, independent of VDD. This allows the device to safely accept input signals exceeding its supply voltage - a key requirement for HIGH-to-LOW level shifting applications. The absolute maximum input voltage is +18 V per limiting values table, but functional operation is guaranteed up to +15.0 V.
Does HEF4050BP,652 support operation at 3.3 V supply?
Yes, HEF4050BP,652 is fully specified for operation from 3.0 V to 15.0 V, including 3.3 V. At VDD = 3.3 V, VIH is guaranteed ≥ 2.3 V and VIL ≤ 1.0 V, ensuring compatibility with standard 3.3 V CMOS logic. Propagation delay increases to approximately 70 ns (typical) at 3.3 V with 50 pF load.
Are pins 13 and 16 on HEF4050BP,652 internally connected?
No, pins 13 and 16 on HEF4050BP,652 are explicitly designated as "not connected" (n.c.) in the official Nexperia datasheet. These pins have no internal bond wires or silicon connections and must remain unconnected in the PCB layout. Grounding or routing them may cause unintended parasitic coupling or violate package thermal design rules.
What is the guaranteed fan-out of HEF4050BP,652 into standard TTL loads?
The HEF4050BP,652 guarantees a fan-out of 2 into standard TTL loads, 9 into 74LS, and 16 into 74L loads per output. This is verified under recommended operating conditions and reflects the device's ability to source/sink sufficient current to maintain valid logic levels across multiple gate inputs without signal degradation.
Is HEF4050BP,652 compliant with JEDEC standards?
Yes, HEF4050BP,652 complies with JEDEC standard JESD13-B for CMOS logic devices. This certification confirms electrical compatibility, timing behavior, and interface characteristics with other JEDEC-compliant logic families, ensuring predictable interoperability in multi-vendor system designs.
