Product details
Overview
HCF4012M013TR from STMicroelectronics is a dual 4-input NAND gate IC in CMOS B-series technology, housed in a 14-pin SOIC package. It delivers symmetrical buffered outputs, 60 ns typical propagation delay at VDD = 10 V, input leakage ≤100 nA 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 legacy system level-shifting.
For engineers reviewing the HCF4012M013TR datasheet, HCF4012M013TR pinout, HCF4012M013TR application, or HCF4012M013TR equivalent, key selection criteria include supply voltage range (3–20 V), dual independent 4-input NAND topology, buffered I/O architecture, quiescent current test coverage up to 20 V, and JEDEC JESD13B compliance for B-series CMOS devices.
Technical Context
The HCF4012M013TR implements two independent 4-input NAND gates with fully buffered inputs and outputs, ensuring noise immunity and consistent drive strength. Its symmetrical output characteristics support balanced rise/fall times (50/50 ns typical at VDD = 10 V) and rail-to-rail voltage swing (VOL = 0.05 V, VOH = 9.95 V @ VDD = 10 V).
Designed for wide-supply operation, it meets JEDEC JESD13B specifications and supports 5 V, 10 V, and 15 V parametric ratings with validated quiescent current testing across all three voltages. Input leakage is specified at ±100 nA max at VDD = 18 V and TA = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 4-input NAND gate - enables compact implementation of complex combinational logic without external fan-in expansion |
| VDD Operating Range | 3 V to 20 V - supports direct integration into mixed-voltage legacy systems including 5 V, 10 V, and 15 V logic rails |
| tPD (Typ.) | 60 ns at VDD = 10 V, CL = 50 pF - defines maximum clock/data rate for synchronous logic stages in industrial timing circuits |
| II (Max) | 100 nA at VDD = 18 V, TA = 25 °C - ensures minimal loading on high-impedance sensor or reference signal sources |
| VOH / VOL | 9.95 V / 0.05 V at VDD = 10 V - provides >9.9 V logic-high margin and <50 mV logic-low threshold for robust noise margin in noisy environments |
| Input/Output Buffering | Fully buffered I/O - eliminates input capacitance stacking and guarantees consistent drive capability across temperature and voltage |
| Temperature Range | –55 °C to +125 °C - qualified for under-hood automotive modules, motor drive controllers, and industrial PLC backplanes |
Pinout & Package
Package: SO-14 (Small Outline Integrated Circuit, 14-pin, 3.9 mm body width, 1.27 mm pitch), per mechanical data PO13G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | J, K - Output | Two independent NAND gate outputs; each drives standard CMOS loads up to 50 pF with full rail-swing capability |
| 2–5 | A–D - Input | First 4-input NAND gate inputs; buffered to reject transient coupling and support daisy-chained logic fan-out |
| 7 | VSS | Negative supply reference (ground); must be low-impedance for stable noise margin and switching integrity |
| 9–12 | E–H - Input | Second 4-input NAND gate inputs; electrically isolated from first gate except via shared VDD/VSS rails |
| 14 | VDD | Positive supply input; accepts 3–20 V DC; internal regulation not present - external decoupling required |
| 6, 8 | NC | No-connect pins; must remain unconnected to avoid parasitic coupling or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC JESD13B Compliance | Fully conforms to B-series CMOS standard - ensures interoperability with legacy 4000-series logic families and predictable timing behavior |
| 100% Quiescent Current Tested | Every unit verified at 5 V, 10 V, and 15 V - guarantees low-power standby operation in battery-backed or energy-sensitive applications |
| Symmetrical Output Drive | Matched tPLH/tPHL (50/50 ns typ. @10 V) - eliminates duty-cycle distortion in clock distribution or pulse shaping networks |
| Wide-Voltage Noise Margin | ≥2 V at VDD = 10 V - sustains reliable logic discrimination in electrically harsh environments such as factory automation or power electronics |
| Buffered I/O Architecture | Input capacitance limited to 7.5 pF max - reduces loading on upstream drivers and enables longer trace routing without signal degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4012BE | DIP-14 package only; identical electrical specs but lacks SOIC variant; higher thermal resistance (RθJA ≈ 100 °C/W vs. 160 °C/W for SO-14) | Preferred for prototyping or through-hole assembly; unsuitable for surface-mount production or space-constrained layouts | Select when manual soldering or breadboard validation is required and board real estate is not constrained |
| MC14012BDR2G | Onsemi part with same pinout and function; wider VDD range (3–18 V vs. 3–20 V); slightly higher tPD (70 ns typ. @10 V) | Valid for most drop-in replacements but requires verification at 18–20 V operation and marginal timing paths | Choose when sourcing continuity is prioritized and 20 V operation is not required in final design |
Compared with CD4012BE and MC14012BDR2G, HCF4012M013TR uniquely supports 20 V absolute maximum supply and offers SO-14 packaging optimized for automated SMT assembly and thermal performance in dense industrial PCBs.

FAQ
Is HCF4012M013TR still in active production?
No - HCF4012M013TR is marked "Obsolete Product(s)" in ST's official documentation. However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle coordination support, including last-time buy planning and cross-reference guidance for functional replacements.
What is the maximum allowable input voltage relative to VDD?
The absolute maximum input voltage is VDD + 0.5 V, per JEDEC JESD13B. Exceeding this risks oxide breakdown in the input protection diodes. For safe operation, inputs must remain within 0 V to VDD, with transient overshoot clamped by external series resistors if needed.
Can HCF4012M013TR drive a 100 pF load reliably?
It is characterized for CL = 50 pF. Driving 100 pF will increase propagation delay (~+30%) and transition time (~+40%), potentially violating setup/hold margins in high-speed designs. For >50 pF loads, verify timing with actual layout parasitics or add a buffer stage.
Does HCF4012M013TR support 3.3 V logic levels?
Yes - it operates down to VDD = 3 V, with VIH = 2.1 V min and VIL = 0.9 V max at that voltage. However, output swing will be ~3.25 V/0.05 V, so interfacing with modern 3.3 V CMOS inputs requires verifying noise margin and fan-out capability per application.
