Product details
Overview
HEF4028BP,652 from Nexperia is a 4-bit BCD-to-decimal decoder IC in SO16 package, operating from 3.0 V to 15.0 V supply, delivering active-HIGH 1-of-10 decoded outputs (Y0–Y9) with propagation delays as low as 30 ns at 15 V, and specified for -40 °C to +85 °C industrial temperature range. It functions as a BCD decoder, 1-of-8 decoder with active-low enable (A3), or 8-output demultiplexer.
For engineers reviewing the HEF4028BP,652 datasheet, HEF4028BP,652 pinout, HEF4028BP,652 application, or HEF4028BP,652 equivalent, key selection considerations include its wide VDD range, CMOS low-power operation, symmetrical output drive, JEDEC JESD13-B compliance, and validated use in discrete logic control, display decoding, and address selection circuits.
Technical Context
The HEF4028BP,652 implements static CMOS logic with fully decoded BCD input mapping (A0–A3) to ten independent active-HIGH outputs (Y0–Y9). Its functional flexibility includes reconfiguration as a 3-bit enabled decoder (A0–A2 select Y0–Y7; A3 = active-low enable) or as an 8-output demultiplexer (A0–A2 = address, A3 = data).
Input clamp diodes allow safe interfacing to voltages exceeding VDD when used with current-limiting resistors. Static characteristics include VIH ≥ 11.0 V and VIL ≤ 4.0 V at 15 V VDD, VOH ≥ 14.95 V, VOL ≤ 0.05 V, and IOL up to 3.6 mA at 15 V - enabling direct LED drive or TTL-level fanout without external buffers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar BCD-to-decimal decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4028BE | Same 4000-series CMOS architecture but packaged in PDIP-16; slightly higher typical propagation delay (180 ns @5 V) | Preferred where through-hole assembly or breadboard prototyping is required | Select CD4028BE only if SO16 surface-mount is incompatible with assembly process or thermal constraints |
| 74HC42D | High-speed CMOS variant; operates only at 2–6 V; no 10–15 V support; faster (20 ns @5 V) but narrower voltage range | Suitable for modern 3.3 V or 5 V digital systems requiring tighter timing margins | Choose 74HC42D when VDD is strictly ≤6 V and sub-25 ns delay is critical; avoid for multi-rail or 10/15 V systems |
Compared with CD4028BE and 74HC42D, the HEF4028BP,652 uniquely supports 3–15 V operation with industrial temperature range and SO16 packaging - making it the only option for mixed-voltage industrial control, legacy system upgrades, and space-constrained 10-output decoding where voltage flexibility and reliability outweigh raw speed.

FAQ
What is the maximum supply voltage rating for HEF4028BP,652?
The absolute maximum supply voltage (VDD) for HEF4028BP,652 is +18 V, per IEC 60134 limiting values. However, the recommended operating range is 3.0 V to 15.0 V. Operation above 15 V is not guaranteed for parametric performance or long-term reliability, and sustained use beyond 15 V may cause accelerated degradation or failure. Always refer to Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) in the official Nexperia HEF4028BP,652 datasheet for design margin guidance.
Does HEF4028BP,652 support demultiplexer functionality?
Yes, HEF4028BP,652 can operate as an 8-output demultiplexer: inputs A0–A2 serve as 3-bit address lines selecting outputs Y0–Y7, while A3 acts as the active-low data input. When A3 is LOW, the addressed output goes HIGH; when A3 is HIGH, all Y0–Y7 remain LOW. This behavior is explicitly defined in Section 1 (General Description) and confirmed in Table 3 (Function Table) of the HEF4028BP,652 datasheet.
What is the pinout compatibility between HEF4028BP,652 and CD4028BE?
HEF4028BP,652 (SO16, SOT109-1) and CD4028BE (PDIP-16) share identical logical pin assignments: A0 (10), A1 (13), A2 (12), A3 (11), Y0 (3), Y1 (14), Y2 (2), Y3 (15), Y4 (1), Y5 (6), Y6 (7), Y7 (4), Y8 (9), Y9 (5), VSS (8), VDD (16). While mechanical packages differ, the HEF4028BP,652 provides true pinout equivalence for redesigns - enabling direct schematic reuse and layout adaptation with only footprint changes required.
Can HEF4028BP,652 drive LEDs directly without external transistors?
Yes, HEF4028BP,652 can directly drive standard LEDs: at 15 V VDD, it delivers up to 3.6 mA sink current (IOL) per output, sufficient for low-current indicator LEDs (e.g., 2 mA @ 2 V forward drop). Use a series current-limiting resistor calculated as R = (VDD − VF) / ILED. For higher-brightness or multiplexed displays, verify total package power dissipation (Ptot ≤ 500 mW) and per-output limit (P ≤ 100 mW) using the HEF4028BP,652 dynamic power formula in Table 8.
Is HEF4028BP,652 qualified for automotive applications?
No, HEF4028BP,652 is not automotive-qualified. The Nexperia datasheet explicitly states in Section 14 (Legal information) that "Unless this data sheet expressly states that this specific Nexperia product is automotive qualified, the product is not suitable for automotive use." HEF4028BP,652 is rated for industrial temperature (-40 °C to +85 °C) but lacks AEC-Q100 qualification, automotive-grade screening, or extended lifetime validation required for automotive ECUs, ADAS, or infotainment systems.
