Product details
Overview
HCF4011BEY from STMicroelectronics is a quad 2-input NAND gate IC in CMOS B-series technology, housed in a 14-pin plastic DIP package. It delivers symmetrical buffered outputs, 60 ns typical propagation delay at VDD = 10 V, ±100 nA input leakage at 18 V, and operates across 3–20 V supply with guaranteed functionality from –55 °C to +125 °C - used in industrial control logic sequencing and power-up reset coordination.
For engineers reviewing the HCF4011BEY datasheet, HCF4011BEY pinout, HCF4011BEY application, or HCF4011BEY equivalent, key selection criteria include supply voltage range (3–20 V), output drive capability (±3.2 mA at VDD = 5 V), noise margin (≥2 V at 10 V), temperature rating (–55 to +125 °C), and JEDEC JESD13B compliance for B-series CMOS devices.
Technical Context
The HCF4011BEY implements four independent NAND gates using standard CMOS transistor pairs with buffered inputs and outputs, ensuring high noise immunity and consistent fan-out loading. Its symmetrical output characteristics support balanced rise/fall times (50/50 ns typical at VDD = 10 V) and rail-to-rail voltage swing.
Designed for wide-supply operation, it maintains specified quiescent current (≤0.5 µA at VDD = 10 V, TA = 25 °C) and input leakage (≤100 nA at VDD = 18 V) across its full –55 to +125 °C operating range, meeting JEDEC JESD13B requirements for B-series CMOS logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 3 V to 20 V - supports single-supply operation across 5 V, 10 V, and 15 V logic systems without level-shifting |
| tPD (Typ.) | 60 ns at VDD = 10 V - enables reliable timing in medium-speed digital control circuits up to ~8 MHz |
| IOH/IOL | –3.2 mA / +3.0 mA at VDD = 15 V - drives ≥2 standard CMOS loads or 1 TTL load directly |
| VIH/VIL | 7 V / 3 V at VDD = 10 V - provides 2 V noise margin for both logic states under nominal supply |
| II (Max) | 100 nA at VDD = 18 V, TA = 25 °C - ensures low standby power in battery-backed or energy-sensitive systems |
| Operating Temp | –55 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and aerospace-adjacent environments |

Key Features
| Feature | Design Value |
|---|---|
| Buffered I/O structure | Reduces capacitive loading sensitivity and improves signal integrity across mixed-logic interfaces |

| 100% tested quiescent current | Guarantees ≤0.5 µA ICC at VDD = 10 V, enabling ultra-low-power sleep-mode logic retention |
| JEDEC JESD13B compliance | Validates interoperability with legacy B-series CMOS families (e.g., CD4000, MC14000) in drop-in replacements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4011BE | Slightly higher tPD (150 ns typ. at 10 V); lower IOL (1.5 mA max at 10 V); no 100% ICC test | Same pinout and truth table; less robust noise margin (1.5 V at 10 V) | Acceptable where speed < 5 MHz and ambient noise is low |
| MC14011BDR2G | SOIC-14 only; tighter VOH/VOL specs (4.98 V / 0.02 V at 5 V); higher VIH (3.65 V min) | No DIP option; better for space-constrained PCBs but requires rework for through-hole legacy designs | Preferred for new SOIC-based designs requiring improved DC accuracy |
Compared with CD4011BE and MC14011BDR2G, the HCF4011BEY offers superior temperature range, guaranteed quiescent current, and DIP-14 availability - making it optimal for industrial repair, high-reliability power sequencing, and legacy-compatible upgrades.

FAQ
Is HCF4011BEY pin-compatible with CD4011BE?
Yes, HCF4011BEY uses identical DIP-14 pinout and truth table as CD4011BE. All eight inputs and four outputs map to the same pins, and both comply with JEDEC JESD13B. No PCB redesign is needed for direct replacement in legacy systems.
What is the maximum safe supply voltage for continuous operation?
The absolute maximum VDD is +22 V, but the recommended operating range is 3 V to 20 V. Continuous operation above 20 V risks permanent damage, even if within absolute ratings - ST specifies 20 V as the upper limit for guaranteed parametric performance and reliability.
Does HCF4011BEY support mixed-voltage interfacing (e.g., 5 V inputs driving a 15 V-powered device)?
No - all inputs must remain within –0.5 V to VDD + 0.5 V. A 5 V signal applied to a 15 V-powered HCF4011BEY violates VI limits and may cause latch-up or accelerated degradation. Level-shifting circuitry is required for cross-voltage domain interfacing.
Can HCF4011BEY drive LEDs directly without current-limiting resistors?
No - although it can sink/source up to 3.2 mA, sustained LED current must be limited externally. Driving an LED directly risks exceeding the 100 mW per-output-transistor rating and causing thermal overstress or parameter drift over time.
