Product details
Overview
HEF4555BP,652 from Nexperia is a dual 1-of-4 CMOS decoder/demultiplexer in SO16 package, operating from 3 V to 15 V supply, with active-LOW enable inputs (1E, 2E), two address inputs per section (1A0/1A1, 2A0/2A1), and eight active-HIGH outputs (1Y0–1Y3, 2Y0–2Y3). It enables address decoding and data routing in industrial control logic and legacy microprocessor peripheral interfaces.
For engineers reviewing the HEF4555BP,652 datasheet, HEF4555BP,652 pinout, HEF4555BP,652 application, or HEF4555BP,652 equivalent, key selection criteria include its dual-decoder architecture, wide VDD range (3–15 V), -40 °C to +85 °C temperature rating, SO16 pin compatibility, and demultiplexing capability using nE as data input.
Technical Context
The HEF4555BP,652 integrates two independent 1-of-4 decoders, each with fully static CMOS operation and symmetrical output drive. Its enable inputs are active LOW, and outputs are mutually exclusive and active HIGH - ensuring only one output per section asserts at any valid address combination.
It supports three standard supply voltages (5 V, 10 V, 15 V) with parametric ratings verified across all, and exhibits high noise immunity with HBM ESD protection exceeding 2000 V. Propagation delays scale inversely with VDD: e.g., tPHL from nA0/nA1 to nYn is typ. 45 ns at 10 V (CL = 50 pF), and 30 ns at 15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VDD) | 3 V to 15 V - supports mixed-voltage system interfacing without level shifters |
| Operating Temperature | -40 °C to +85 °C - qualified for industrial ambient environments |
| Propagation Delay (tPHL/tPLH) | 30 ns max at 15 V (CL = 50 pF) - enables reliable timing in medium-speed digital control |
| Output Drive (IOL/IOH) | ±3.6 mA at 15 V - sufficient to directly drive TTL loads or small LED indicators |
| Input Leakage Current | ±1.0 μA max at 15 V - ensures low standby power and stable logic levels with high-impedance sources |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 for robust handling in assembly |
| Static Power Dissipation | 600 μA max IDD at 15 V - ultra-low quiescent current for battery-backed or energy-sensitive designs |
Pinout & Package
HEF4555BP,652 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 PCB assembly and IPC-7351 footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1E, 2E | Active-LOW enable inputs - assert decoder function only when LOW; HIGH forces all outputs LOW |
| 2, 3, 14, 13 | 1A0, 1A1, 2A0, 2A1 | Binary address inputs - select one of four outputs per decoder section (00→Y0, 01→Y1, etc.) |
| 4–7, 9–12 | 1Y0–1Y3, 2Y0–2Y3 | Active-HIGH decoded outputs - only one per section is HIGH per valid address+enable state |
| 8 | VSS | Ground reference - must be connected to system GND; unused inputs tied here meet logic LOW requirement |
| 16 | VDD | Positive supply - powers both decoder sections; supports 3–15 V with full parametric compliance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent decoders | Two fully isolated 1-of-4 sections on one die - eliminates need for two discrete ICs in address/data fanout |
| Wide VDD range (3–15 V) | Operates across legacy 5 V, modern 3.3 V (with margin), and high-voltage industrial rails - no external regulators required |
| Demultiplexing mode | Enable input (nE) serves as data path - transforms decoder into 1-to-4 data switch with address-controlled routing |
| JEDEC JESD13-B compliance | Guarantees interoperability with industry-standard CMOS logic families and test methodologies |
| High noise immunity | CMOS input thresholds (VIH ≥ 11 V @ 15 V, VIL ≤ 4 V @ 15 V) provide >4 V noise margin in high-noise industrial settings |
Applications
| Industrial PLC I/O Expansion | Legacy Microprocessor Address Decoding |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar decoder/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4555BE | Same dual 1-of-4 function but TI-manufactured; wider VDD range (3–18 V); slightly higher max propagation delay (75 ns @ 15 V) | Valid for higher-voltage industrial systems (>15 V) but lacks JEDEC JESD13-B certification | Prefer HEF4555BP,652 when JEDEC compliance or tighter timing (30 ns vs 75 ns) is required |
| 74HC155 | Single 1-of-4 decoder with dual enable (active HIGH + active LOW); 2–6 V VDD range; faster (19 ns @ 5 V) but narrower voltage support | Suitable for 5 V-only systems needing lower propagation delay, but requires two ICs for dual-section functionality | Choose HEF4555BP,652 when dual independent decoders and 3–15 V operation are mandatory |
Compared with CD4555BE and 74HC155, the HEF4555BP,652 uniquely delivers dual-section decoding, JEDEC-compliant operation, and guaranteed sub-65 ns timing across the full 3–15 V range - making it optimal for industrial control upgrades requiring drop-in compatibility with legacy 4000-series logic.

FAQ
What is the maximum supply voltage the HEF4555BP,652 can tolerate continuously?
The HEF4555BP,652 has an absolute maximum supply voltage (VDD) of +18 V per Table 4 in its datasheet. However, continuous operation above 15 V is not recommended - the device is fully characterized and guaranteed only up to 15 V under recommended operating conditions. Exceeding 15 V risks violating parametric limits and may cause accelerated aging or failure.
Can the HEF4555BP,652 be used as a 1-to-4 demultiplexer, and how is that configured?
Yes, the HEF4555BP,652 functions as a 1-to-4 demultiplexer by using the enable input (1E or 2E) as the data input and the address inputs (1A0/1A1 or 2A0/2A1) to select the output. When nE is LOW, the selected nYn output mirrors the nE logic state (i.e., HIGH), while all others remain LOW - enabling true data routing behavior confirmed in Table 3 (Function Selection).
Does the HEF4555BP,652 support 3.3 V logic systems, and what are the input threshold implications?
Yes, the HEF4555BP,652 operates down to 3 V VDD and supports 3.3 V systems. At VDD = 3.3 V, VIH is min. 2.31 V and VIL is max. 0.99 V (interpolated from Table 6), providing ~0.7 V noise margin for standard 3.3 V CMOS outputs. Input leakage remains below 150 μA, ensuring compatibility with high-impedance 3.3 V drivers.
How does the HEF4555BP,652 handle unused inputs, and why is this critical?
Unused inputs on the HEF4555BP,652 must be tied to VDD, VSS, or another driven input - floating CMOS inputs cause increased supply current, erratic switching, and potential latch-up. This requirement is explicitly stated in Section 1 and enforced by the device's high-impedance gate structure; leaving inputs unconnected violates recommended operating conditions and risks functional failure.
Is the HEF4555BP,652 pin-compatible with older HEF4555P variants in DIP packages?
No - the HEF4555BP,652 uses SO16 (SOT109-1) packaging, while legacy HEF4555P variants use 16-pin DIP (SOT38-4). Although both share identical logic function and pin numbering (per functional diagram and pin description), the physical package, thermal characteristics, and soldering requirements differ. PCB layout and reflow profiles must be updated for SO16.
