NXP Semiconductors HEF4001BP,652

Overview

HEF4001BP,652 from Nexperia is a quad 2-input NOR gate CMOS logic IC operating from 3.0 V to 15.0 V supply, delivering symmetrical output drive, high noise immunity, and fully static operation across -40 °C to +125 °C. It integrates input clamp diodes enabling safe interfacing with voltages exceeding VDD using current-limiting resistors, and is commonly used in digital control logic, reset signal conditioning, and combinational logic synthesis.

For engineers reviewing the HEF4001BP,652 datasheet, HEF4001BP,652 pinout, HEF4001BP,652 application, or HEF4001BP,652 equivalent, key selection criteria include supply voltage range (3–15 V), guaranteed operation up to +125 °C, SO14 package compatibility, propagation delay (20–120 ns depending on VDD and load), and ESD robustness (HBM >2000 V, CDM >1000 V).

Technical Context

The HEF4001BP,652 implements four independent 2-input NOR gates in a single monolithic CMOS structure, each with identical input/output characteristics and rail-to-rail voltage handling. Its inputs feature integrated clamp diodes referenced to VSS and VDD, allowing overvoltage tolerance when used with external series resistors.

It supports three standard supply rails - 5 V, 10 V, and 15 V - with parametric ratings verified across all, and complies with JEDEC JESD13-B for standardized logic behavior. Static operation ensures zero dynamic power consumption at DC, while propagation delays scale predictably with supply voltage and capacitive load per extrapolation formulas in the datasheet.

FAQ

What is the maximum supply voltage rating for HEF4001BP,652?

The absolute maximum supply voltage (VDD) for HEF4001BP,652 is +18 V, though the recommended operating range is 3.0 V to 15.0 V. Operation above 15 V is not characterized for timing or drive performance and may impact long-term reliability. All parametric specifications - including propagation delay, output drive, and noise margins - are guaranteed only within the 3–15 V range per the datasheet.

Does HEF4001BP,652 support operation at +125 °C?

Yes, HEF4001BP,652 is fully specified and tested for continuous operation from -40 °C to +125 °C. Static and dynamic parameters - including VIH/VIL thresholds, VOL/VOH levels, propagation delay, and supply current - are guaranteed across this full range. The SO14 package (SOT108-1) is thermally rated for this temperature span with appropriate PCB copper pour and airflow.

Is HEF4001BP,652 pin-compatible with CD4001BE?

Yes, HEF4001BP,652 and CD4001BE share identical pinout (14-pin SO), logic function, and terminal assignments (VSS = pin 7, VDD = pin 14, etc.). However, HEF4001BP,652 offers JEDEC JESD13-B compliance and documented HBM/CDM ESD ratings (>2000 V / >1000 V), whereas CD4001BE does not specify these in its public documentation. Electrical behavior is otherwise functionally equivalent.

What is the typical propagation delay of HEF4001BP,652 at 5 V supply?

At VDD = 5 V and CL = 50 pF, the typical propagation delay (tPHL/tPLH) of HEF4001BP,652 is 60 ns, with a maximum of 120 ns. This value is derived from the extrapolation formula tPHL = 33 + 0.55 × CL (ns), confirmed in Table 7 of the datasheet. Delay decreases significantly at higher supply voltages - e.g., 20 ns typical at 15 V.

Can HEF4001BP,652 inputs safely interface with 24 V signals?

No - HEF4001BP,652 inputs tolerate only up to VDD + 0.5 V per the limiting values table. With VDD = 15 V, the absolute maximum input voltage is +15.5 V. For 24 V signal interfacing, an external series current-limiting resistor must be used in conjunction with the internal clamp diodes, and VDD must be set to ≥18 V (beyond absolute max) - which is not allowed. Instead, use a dedicated level translator or voltage divider to reduce the 24 V signal to ≤15.5 V before applying it to HEF4001BP,652.
