Product details
Overview
HEF4023BP,652 from NXP Semiconductors (formerly Philips) is a triple 3-input NAND gate IC in the HE4000B LOCMOS logic family, operating at supply voltages of 5 V, 10 V, or 15 V, with propagation delays as low as 15 ns at 15 V and CL = 50 pF, used in digital control logic, address decoding, and combinational logic circuits.
For engineers reviewing the HEF4023BP,652 datasheet, HEF4023BP,652 pinout, HEF4023BP,652 application, or HEF4023BP,652 equivalent, key selection criteria include supply voltage range (5–15 V), triple-gate integration, DIL-14 plastic package compatibility, and noise-immune buffered outputs for stable TTL/CMOS interface designs.
Technical Context
The HEF4023BP,652 implements three independent 3-input NAND gates using LOCMOS (Low-power CMOS) technology, delivering high noise immunity via fully buffered outputs and pattern-insensitive output impedance. Each gate exhibits symmetrical HIGH-to-LOW and LOW-to-HIGH propagation delays across its rated VDD range.
AC performance is specified at Tamb = 25 °C with CL = 50 pF and input transition times ≤20 ns; delay values scale predictably with load capacitance per published formulas (e.g., tPLH = 17 ns + 0.16 ns/pF × CL at VDD = 15 V), enabling accurate timing budgeting in synchronous logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | HE4000B LOCMOS - enables direct interfacing with TTL and standard CMOS while maintaining low static power draw |
| Supply Voltage (VDD) | 5 V / 10 V / 15 V - supports multi-rail legacy industrial and instrumentation systems without level-shifting |
| Propagation Delay (tPLH/tPHL) | 15 ns max at VDD = 15 V, CL = 50 pF - ensures reliable operation in 30 MHz+ clock domains with margin |
| Output Drive | Fully buffered outputs - eliminates waveform distortion under varying capacitive loads and improves signal integrity |
| Input Transition Time | ≤20 ns - defines maximum allowable edge rate for guaranteed timing compliance and noise rejection |
| Dynamic Power (P) | 16.4 mW × fi + Σ(foCL) × VDD² at 15 V - allows precise power estimation for thermal design in dense logic layouts |
Pinout & Package
HEF4023BP,652 uses a 14-lead dual-in-line plastic package (SOT27-1, DIP-14), with 0.3-inch body width and standard through-hole mounting footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A/B/C of Gate 1 | Three independent logic inputs to first NAND gate; all must be HIGH for LOW output |
| 4 | Output Y1 | Active-LOW output of Gate 1; drives downstream logic or pull-up networks |
| 5, 6, 13 | Input A/B/C of Gate 2 | Three inputs to second NAND gate; pin 13 is shared with Gate 3 input for compact layout |
| 7 | VSS | Ground reference for all gates; requires low-impedance PCB connection to minimize noise coupling |
| 8, 9, 10 | Input A/B/C of Gate 3 | Inputs to third NAND gate; pin 8 is shared with Gate 2 input (pin 5) per functional diagram |
| 11 | Output Y2 | Active-LOW output of Gate 2; electrically isolated from Y1/Y3 but shares VDD/VSS rails |
| 12 | Output Y3 | Active-LOW output of Gate 3; supports fan-out to ≥10 standard CMOS loads |
| 14 | VDD | Positive supply rail; decoupling capacitor (100 nF) required within 10 mm of pin for AC stability |
Key Features
| Feature | Design Value |
|---|---|
| Triple 3-input NAND function | Integrates three independent logic gates in one DIP-14 package, reducing board space and interconnect count vs. discrete gates |

Applications
| Industrial Control Logic | Legacy Instrumentation Interface |
|---|---|

| Digital Panel Mux Control | Power Sequencing Enable Logic |
Use Scenario: Selecting between multiple display segments on an LED-based status panel using three front-panel switch inputs. IC Role / Device Role / Timing Role: HEF4023BP,652 acts as a combinatorial selector enabling/disabling segment drivers based on user-configurable dip-switch settings. Use Value: Low input capacitance (<10 pF) prevents loading of mechanical switch nodes, eliminating debounce circuitry in cost-sensitive designs. | Use Scenario: Enabling 5 V, 12 V, and 3.3 V power rails only after all preconditions (voltage OK, thermal OK, enable button pressed) are met. IC Role / Device Role / Timing Role: HEF4023BP,652 serves as a hardware-enforced AND-of-three condition (inverted as NAND), providing fail-safe power-up sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4023BE | Same pinout and logic function; higher typical propagation delay (40 ns @ 15 V, CL = 50 pF) and wider delay variation across temperature | Less suitable for timing-critical 10+ MHz control paths; acceptable for slow-switching power management logic | Select CD4023BE only when legacy BOM alignment or distributor stock availability outweighs timing performance needs |
| 74HC10N,652 | Pin-compatible 14-lead DIP; operates at 2–6 V only; faster (15 ns @ 6 V) but incompatible with 10/15 V systems | Requires level-shifting or separate 5 V rail; unsuitable for existing 12/15 V industrial designs without redesign | Choose 74HC10N,652 only in new 5 V-only designs prioritizing speed and lower dynamic power over voltage flexibility |
Compared with CD4023BE and 74HC10N,652, the HEF4023BP,652 uniquely supports 5–15 V operation with predictable delay scaling and buffered outputs-making it the sole option for retrofitting legacy 12/15 V systems while maintaining timing integrity and noise resilience.

FAQ
What is the maximum operating supply voltage for HEF4023BP,652?
The HEF4023BP,652 supports a maximum supply voltage of 15 V DC, with full AC and DC specifications guaranteed across 5 V, 10 V, and 15 V operation. Operation above 15 V risks permanent damage and voids parametric guarantees. The HEF4023BP,652 must be decoupled with a 100 nF ceramic capacitor placed within 10 mm of the VDD pin to maintain stability at this voltage.
Does HEF4023BP,652 have pin-to-pin compatibility with CD4023BE?
Yes, HEF4023BP,652 and CD4023BE share identical pinout, terminal functions, and DIP-14 package dimensions (SOT27-1). However, HEF4023BP,652 offers tighter propagation delay specs and superior noise immunity due to its fully buffered outputs-so while physically interchangeable, timing-critical designs may require validation when substituting HEF4023BP,652 for CD4023BE.
What is the input capacitance specification for HEF4023BP,652?
The typical input capacitance of HEF4023BP,652 is 7.5 pF per input pin, with a maximum of 10 pF over temperature and voltage ranges. This low value minimizes loading on upstream drivers and enables reliable operation with high-impedance sources such as mechanical switches or open-collector outputs-critical for HEF4023BP,652 applications in industrial control panels.
Can HEF4023BP,652 drive LED loads directly?
No, HEF4023BP,652 is not designed for direct LED driving: its output current capability is limited to ±1 mA (typical) at VDD = 15 V, insufficient for visible LEDs requiring 5–20 mA. For indicator use, HEF4023BP,652 outputs must interface with external driver transistors or buffer ICs-this limitation is inherent to LOCMOS output stage design and applies across all HE4000B family members.
Is HEF4023BP,652 RoHS compliant?
HEF4023BP,652 was originally manufactured prior to RoHS enforcement and contains lead in its solderable leads and internal die attach. NXP does not offer a RoHS-compliant reflowable variant of this exact part number. For new designs requiring RoHS compliance, consider functional alternatives like 74HC10N,652 (RoHS-compliant, 5 V only) or contact Aetrix Electronics for verified drop-in replacements with full compliance documentation.
