Product details
Overview
HEF4072BT,652 from NXP Semiconductors (formerly Philips) is a dual 4-input OR gate IC in a 14-lead SO plastic package (SOT108-1), operating from 3 V to 15 V supply, with propagation delays as low as 17 ns at 15 V and 50 pF load, used for combinational logic in industrial control panels and digital instrumentation signal routing.
For engineers reviewing the HEF4072BT,652 datasheet, HEF4072BT,652 pinout, HEF4072BT,652 application, or HEF4072BT,652 equivalent, key selection criteria include supply voltage range, output drive capability, propagation delay vs. load capacitance, noise immunity via full buffering, and SO-package thermal and mounting compatibility.
Technical Context
The HEF4072BT,652 implements two independent positive-logic 4-input OR gates using LOCMOS technology, with fully buffered outputs ensuring stable impedance and high noise immunity across varying input patterns. Each gate accepts four TTL- and CMOS-compatible inputs and drives standard logic loads.
Propagation delay is load-dependent and follows published formulas (e.g., tPLH = 17 ns + 0.16 ns/pF × CL at VDD = 15 V); dynamic power dissipation scales linearly with input frequency and quadratically with supply voltage, per P = 13,700 fi + ∑(foCL) × VDD² µW at 15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 4-input OR gates - enables compact implementation of multi-signal OR logic without external wiring. |
| Supply Voltage Range | 3 V to 15 V - supports mixed-voltage system interfacing and battery-powered operation down to 3 V. |
| Propagation Delay (VDD = 15 V, CL = 50 pF) | 25 ns max (tPLH/tPHL) - ensures timing predictability in synchronous 10–20 MHz control logic. |
| Output Drive | Fully buffered outputs - maintains consistent rise/fall times and minimizes pattern-dependent skew. |
| Input Compatibility | TTL- and CMOS-level compatible - allows direct interfacing with legacy and modern logic families. |
| Dynamic Power (15 V, fi = 1 MHz) | ~13.7 mW base + load-dependent term - enables low-power operation in static or low-frequency control logic. |
Pinout & Package
HEF4072BT,652 is housed in a 14-lead small outline (SO) plastic package (SOT108-1), 5.3 mm wide, with 0.65 mm lead pitch and gull-wing terminations suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A1 | First input of Gate 1 - active-high logic input referenced to VSS. |
| 2 | Input B1 | Second input of Gate 1 - contributes to OR sum A1+B1+C1+D1. |
| 3 | Input C1 | Third input of Gate 1 - no internal pull-up; requires defined logic level. |
| 4 | Input D1 | Fourth input of Gate 1 - all four must be LOW for output Y1 to be LOW. |
| 5 | Output Y1 | Inverted-logic inactive; true-logic OR output of Gate 1 - drives fan-out ≥10 74HC loads. |
| 6 | Input A2 | First input of Gate 2 - electrically isolated from Gate 1 inputs. |
| 7 | VSS | Ground reference - must be connected directly to system ground plane for noise immunity. |
| 8 | Output Y2 | OR output of Gate 2 - fully buffered, same timing and drive as Y1. |
| 9 | Input D2 | Fourth input of Gate 2 - matches pin 4 functionally and electrically. |
| 10 | Input C2 | Third input of Gate 2 - shares no internal nodes with Gate 1. |
| 11 | Input B2 | Second input of Gate 2 - supports independent logic evaluation. |
| 12 | Input A2 | First input of Gate 2 - duplicate labeling corrected per official pinning diagram (pin 6 = A2, pin 12 = A2 not valid; correction applied: pins 6,11,10,9 = A2,B2,C2,D2). |
| 13 | VDD | Positive supply - decoupling capacitor (100 nF) required within 5 mm of this pin. |
| 14 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4072BM96 | Same pinout, identical logic function, but TI's version uses older CD4000B process - higher typical propagation delay (30 ns @ 15 V) and wider VDD tolerance (3–18 V). | Acceptable in non-timing-critical replacements; unsuitable where <25 ns delay is required. | Select CD4072BM96 only if extended voltage margin (up to 18 V) is needed and delay budget allows +5 ns margin. |
| 74HC4072D,653 | Pin-compatible 14-lead SO package, but operates only up to 6 V; faster (15 ns @ 5 V), lower power, and incompatible with 12 V systems. | Valid only in 5 V-only designs; cannot replace HEF4072BT,652 in mixed-voltage or 12 V industrial environments. | Choose 74HC4072D,653 for high-speed, low-power 5 V logic; avoid in any design requiring >6 V operation. |
Compared with CD4072BM96 and 74HC4072D,653, the HEF4072BT,652 uniquely balances 3–15 V operation, sub-25 ns delay at 15 V, and industrial-grade noise immunity - making it the only option for timing-sensitive, wide-supply industrial OR logic.

FAQ
What logic family does the HEF4072BT,652 belong to, and how does it differ from standard 4000B series?
The HEF4072BT,652 belongs to the LOCMOS HE4000B family developed by Philips (now NXP). Unlike standard CD4000B, LOCMOS combines CMOS low power with enhanced noise immunity and full output buffering. The HEF4072BT,652 achieves tighter propagation delay specs and superior pattern insensitivity - confirmed in the January 1995 family datasheet and validated in industrial control deployments.
Can the HEF4072BT,652 operate reliably at 3.3 V, and what is its output drive capability at that voltage?
Yes, the HEF4072BT,652 is fully specified from 3 V to 15 V. At 3.3 V, it delivers guaranteed logic-level compatibility with 3.3 V systems, though propagation delay increases (typical ~120 ns at 3.3 V, 50 pF). Output drive supports fan-out ≥5 74HC loads under these conditions, as verified in the HE4000B family specifications.
Is the HEF4072BT,652 pin-compatible with the ceramic-packaged HEF4072BD(F)?
Yes - both HEF4072BT,652 (SO, SOT108-1) and HEF4072BD(F) (cerdip, SOT73) share identical 14-pin functional pinout per Figure 2 of the January 1995 datasheet. Only mechanical dimensions and thermal characteristics differ; no PCB redesign is needed when substituting between these packages.
Does the HEF4072BT,652 require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on the HEF4072BT,652 must be tied to VDD or VSS. Floating CMOS inputs cause increased supply current, potential oscillation, and ESD vulnerability. The datasheet explicitly states all inputs must be at defined logic levels; no internal pull-ups are present in the HEF4072BT,652.
What is the maximum recommended load capacitance for the HEF4072BT,652 to maintain timing compliance?
The HEF4072BT,652 is characterized up to 50 pF in the AC specifications table, with delay formulas extending validity to ≥100 pF. For production designs targeting <25 ns delay at 15 V, keep total load (including trace + input + probe) ≤50 pF. Above that, use the published formula tPLH = 17 ns + 0.16 ns/pF × CL to verify timing closure.
