Product details
Overview
74HC20PW,112 from Nexperia is a dual 4-input NAND gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 8 ns at VCC = 6.0 V and CL = 50 pF, rated for -40 °C to +125 °C ambient temperature, and used in digital logic control, address decoding, and bus arbitration circuits.
For engineers reviewing the 74HC20PW,112 datasheet, 74HC20PW,112 pinout, 74HC20PW,112 application, or 74HC20PW,112 equivalent, this device serves as a standard CMOS logic building block requiring precise input threshold compatibility, low-power static operation, and robust ESD immunity in industrial control and instrumentation signal conditioning paths.
Technical Context
The 74HC20PW implements two independent 4-input NAND gates with CMOS input structure, clamp diodes on all inputs enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Its logic function follows standard Boolean NAND behavior: output HIGH only when all four inputs are LOW.
It operates across wide voltage (2.0–6.0 V) and temperature (-40 °C to +125 °C) ranges, complies with JEDEC JESD7A and JESD8C standards, and features HBM ESD protection >2000 V and CDM >1000 V - critical for handling in automated assembly and field-replaceable modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V microcontroller controlling 5 V peripherals). |
| Propagation Delay (tpd) | 8 ns (typ.) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-100 MHz synchronous logic designs. |
| Output Drive (IO) | ±25 mA - sufficient to drive multiple 74HC inputs or small LED loads without external buffers. |
| Input Thresholds (VIH/VIL) | VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V - ensures noise margin >1.2 V and compatibility with TTL and CMOS logic families. |
| Power Dissipation (Ptot) | 500 mW max (derates 7.3 mW/K above +81 °C) - defines thermal design limits for high-density PCB layouts. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD robustness. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1), 14-lead, body width 4.4 mm, 0.65 mm pitch, lead finish matte tin, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | 1A, 1B, 1C, 1D | First NAND gate inputs - all must be LOW to assert HIGH on Pin 6. |
| 3, 11 | n.c. | No internal connection - must remain unconnected; no pull-up/down required. |
| 6 | 1Y | Output of first NAND gate - active-low logic result of 1A•1B•1C•1D. |
| 7 | GND | Ground reference - must be low-impedance return path for all internal switching currents. |
| 8 | 2Y | Output of second NAND gate - active-low logic result of 2A•2B•2C•2D. |
| 9, 10, 12, 13 | 2A, 2B, 2C, 2D | Second NAND gate inputs - independent of first gate; supports dual-channel logic functions. |
| 14 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation enables drop-in use across 3.3 V and 5 V systems without level shifters. |
| Input clamp diodes | Allow safe interface to signals up to VCC + 0.5 V using series current-limiting resistors - eliminates need for external protection diodes. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| Low static current | ICC ≤ 40 μA at VCC = 6.0 V and full temperature range - minimizes quiescent power in battery-backed logic. |
| High noise immunity | CMOS input thresholds provide >40 % VCC noise margin - suppresses false triggering in electrically noisy environments like motor drives. |
Applications
| Industrial PLC Input Decoding | Microcontroller Address Bus Expansion |
|---|---|
|
Use Scenario: A programmable logic controller uses discrete sensor inputs to generate enable signals for analog input modules. IC Role / Device Role / Timing Role: Dual NAND gate performs wired-OR logic reduction of four limit switch states into one channel-select strobe. Use Value: Eliminates need for discrete diode-resistor networks while maintaining <10 ns timing skew between channels. |
Use Scenario: An ARM Cortex-M4 MCU with limited GPIO expands its 16-bit address bus to access external SRAM and FPGA configuration space. IC Role / Device Role / Timing Role: One gate decodes A14–A17 to select memory-mapped peripherals; second gate enables chip-select for SPI flash. Use Value: Provides deterministic 8 ns propagation delay, ensuring setup/hold compliance with 50 MHz bus timing. |
| Automotive Body Control Module Logic | Test Equipment Signal Conditioning |
|
Use Scenario: A BCM validates door lock actuator readiness by AND-ing four sensor feedback lines before enabling driver ICs. IC Role / Device Role / Timing Role: Configured as active-low NAND to detect all sensors asserted (LOW), asserting enable only when ready. Use Value: Rated for -40 °C to +125 °C and qualified per JESD78 latch-up spec - survives under-dash thermal cycling. |
Use Scenario: Automated test equipment verifies logic state transitions on DUT pins using synchronized stimulus and capture. IC Role / Device Role / Timing Role: Gates combine multiple trigger sources (oscilloscope edge, pattern generator, manual button) into single gated clock. Use Value: Low 0.26 V VOL at 4 mA ensures clean TTL-compatible logic levels into scope trigger inputs. |
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 |
|---|---|---|---|
| 74HC20D,653 | SO14 package (SOT108-1), 3.9 mm body width, higher thermal resistance (10.1 mW/K derating above 100 °C). | Better suited for through-hole prototyping or legacy board rework where SO14 footprint exists. | Select when mechanical compatibility with existing SO14 land patterns is required and thermal load is moderate. |
| SN74HC20DR | Texas Instruments part in SOIC-14; VIH/VIL tighter (3.15 V/1.35 V at VCC = 4.5 V), tpd slightly slower (13 ns typ). | Preferred in TI-centric designs with strict qualification traceability and long-term supply commitments. | Choose when TI's 10-year longevity program or specific automotive PPAP documentation is mandated. |
Compared with 74HC20PW,112, the SO14 variant offers easier hand-soldering but lower power density, while the TI alternative provides stronger process control documentation at the cost of marginal speed penalty and different supply chain sourcing.

FAQ
Can 74HC20PW,112 operate reliably at 2.0 V supply?
Yes - the device is fully specified down to 2.0 V supply, with guaranteed VIH ≥ 1.5 V and VOL ≤ 0.5 V at 2.0 V and -40 °C to +85 °C. Propagation delay increases to 90 ns (max) at this voltage, making it suitable for low-power, low-speed monitoring circuits where energy efficiency outweighs speed.
Are pins 3 and 11 internally connected?
No - pins 3 and 11 are explicitly designated "n.c." (not connected) in the official Nexperia datasheet. They have no internal bond wire or silicon connection and must remain unconnected on the PCB; routing traces or applying solder to them may cause mechanical stress or unintended coupling.
What is the maximum capacitive load for stable 74HC20PW,112 operation?
The device is characterized up to 50 pF load capacitance per output, with propagation delay and transition time data provided at that value. Driving >50 pF is possible but degrades tpd and tt linearly; for 100 pF loads, expect ~2× delay increase and potential ringing without series termination - add a 33 Ω resistor in series with each output if driving >75 pF.
Does 74HC20PW,112 support mixed-voltage interfacing (e.g., 3.3 V inputs with 5 V supply)?
Yes - input clamp diodes allow safe interface to voltages up to VCC + 0.5 V when series current-limiting resistors are used. For 3.3 V inputs into a 5 V-powered 74HC20PW, a 1 kΩ resistor per input limits clamp current to <2 mA, satisfying the ±20 mA absolute maximum rating and preventing damage.
