Product details
Overview
74HC20PW,118 from Nexperia is a dual 4-input CMOS 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, used for digital logic level translation and combinational logic in industrial control and embedded interface circuits.
For engineers reviewing the 74HC20PW,118 datasheet, 74HC20PW,118 pinout, 74HC20PW,118 application, or 74HC20PW,118 equivalent, this device supports high-noise-immunity logic design, voltage-level flexible interfacing via input clamp diodes, and robust latch-up performance exceeding 100 mA per JESD78 Class II Level B.
Technical Context
The 74HC20PW implements two independent 4-input NAND functions with CMOS input thresholds (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), enabling reliable interfacing with TTL and other 3.3 V/5 V logic families. Each gate output drives ±4.0 mA at VCC = 4.5 V with VOL ≤ 0.26 V and VOH ≥ 3.98 V.
It features integrated input clamp diodes allowing safe interface to voltages above VCC when used with current-limiting resistors, and meets JEDEC JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V) standards. ESD protection exceeds 2000 V HBM and 1000 V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct operation across 3.3 V and 5 V systems without level shifters. |
| Propagation Delay (tpd) | 8 ns (typ) at VCC = 6.0 V, CL = 50 pF - Supports >50 MHz toggle rates in synchronous logic paths. |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - Sufficient to drive 10 LS-TTL loads or multiple CMOS inputs. |
| Input Clamp Diodes | Integrated - Allows safe overvoltage input handling up to VCC + 0.5 V with external current limiting. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood industrial and extended-temperature embedded applications. |
| Power Dissipation (Ptot) | 500 mW max (derates 7.3 mW/K above 81 °C) - Matches thermal limits of TSSOP14 footprint on standard PCBs. |
| Static Supply Current (ICC) | 40 μA max at VCC = 6.0 V, -40 °C to +125 °C - Ensures ultra-low quiescent power in battery-backed logic. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, body width 4.4 mm, 0.65 mm lead pitch, 1.20 mm max height - optimized for high-density PCB layouts with improved thermal dissipation vs SO14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | 1A, 1B, 1C, 1D | Inputs to first NAND gate - all four must be HIGH for output 1Y to go LOW. |
| 3, 11 | n.c. | No-connect pins - must remain unconnected; no internal connection or function. |
| 6 | 1Y | Active-Low output of first NAND gate - sinks or sources current per logic state. |
| 7 | GND | Ground reference (0 V) - return path for all input/output currents and supply decoupling. |
| 8 | 2Y | Active-Low output of second NAND gate - electrically isolated from 1Y. |
| 9, 10, 12, 13 | 2A, 2B, 2C, 2D | Inputs to second NAND gate - fully independent logic channel from first gate. |
| 14 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V - eliminates need for separate voltage rails in mixed-supply systems. |
| High noise immunity | Typical VIH/VIL margins >1.3 V at VCC = 4.5 V - rejects transient coupling in noisy industrial environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during ESD or surge events. |
| Input clamp diodes | Enabled on all inputs - permits safe interfacing to 12 V control signals using simple series resistors. |
| Low dynamic power | CPD = 22 pF - enables sub-mW switching power at 1 MHz with 50 pF load. |
Applications

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; Ptot derates 10.1 mW/K above 100 °C. | Better board-level thermal mass; less suitable for ultra-high-density layouts than TSSOP. | Select when legacy footprint compatibility or higher thermal inertia is required. |
| SN74HC20DR | Texas Instruments part; identical logic function but different VIL/VOH specs (VIL = 1.2 V min at VCC = 4.5 V). | Slightly lower noise margin; not drop-in for designs relying on Nexperia's tighter VIH/VIL thresholds. | Choose only after validating input threshold compatibility in target voltage corners. |
Compared with 74HC20D,653, the 74HC20PW,118 offers finer pitch and lower profile for space-constrained boards; versus SN74HC20DR, it delivers superior noise immunity due to higher VIH (3.15 V) and lower VIL (1.35 V) at 4.5 V.

FAQ
What is the maximum clock frequency supported by the 74HC20PW,118?
The 74HC20PW,118 is a combinational logic device with no internal clock; its usable toggle rate depends on propagation delay and load. With tpd = 8 ns (typ) at VCC = 6.0 V and CL = 50 pF, it supports reliable operation up to ~50 MHz in feedback-free configurations. For oscillatory use, external RC timing must account for worst-case 27 ns delay at 125 °C.
Can the 74HC20PW,118 safely interface with 12 V signals?
Yes - all inputs include clamp diodes to VCC and GND. When a 12 V signal is applied through a current-limiting resistor (e.g., 10 kΩ), input current remains below ±20 mA absolute maximum, preventing damage. The resistor value must ensure IIK ≤ 20 mA at (12 V − VCC), e.g., 470 Ω minimum for VCC = 5 V.
Are pins 3 and 11 internally connected?
No - pins 3 and 11 are explicitly designated "n.c." (no connect) in the official Nexperia datasheet. They have no internal bond wire or silicon connection and must remain unconnected on PCB layout to avoid parasitic coupling or unintended current paths.
How does the 74HC20PW,118 differ from the 74HCT20 variant?
The 74HC20PW,118 uses CMOS input thresholds (VIH ≈ 70% VCC), while 74HCT20 uses TTL-compatible thresholds (VIH = 2.0 V fixed). This makes the HC version better suited for mixed-voltage systems where VCC varies, whereas HCT ensures compatibility with legacy 5 V TTL outputs regardless of supply voltage.
