Product details
Overview
74HC20D-Q100 from Nexperia is a dual 4-input NAND gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V–6.0 V, propagation delay as low as 8 ns at VCC = 6.0 V/CL = 50 pF, and CMOS-level input compatibility - deployed in engine control unit (ECU) logic sequencing and body electronics power-on reset coordination.
For engineers reviewing the 74HC20D-Q100 datasheet, 74HC20D-Q100 pinout, 74HC20D-Q100 application, or 74HC20D-Q100 equivalent, key selection considerations include automotive temperature compliance, dual independent NAND functionality with clamp diodes for overvoltage-tolerant interfacing, SO14 package mechanical fit, and static/dynamic DC characteristics across full VCC and temperature range.
Technical Context
This device implements two independent 4-input NAND gates in a single monolithic CMOS structure, each with Schmitt-trigger–free inputs and rail-to-rail output swing. Input clamp diodes enable safe interface to signals exceeding VCC when used with current-limiting resistors.
It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports HBM ESD >2000 V and CDM >1000 V, and exhibits latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 4-input NAND gate - enables compact implementation of multi-input logic conditions without external fan-in. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration into 3.3 V and 5.0 V automotive subsystems without level-shifting. |
| Propagation Delay | 8 ns typical at VCC = 6.0 V, CL = 50 pF - ensures timing-critical combinatorial logic meets sub-10 ns budget in ECU signal conditioning paths. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission-control module deployment. |
| Input Clamp Diodes | Integrated on all inputs - permits robust interfacing to 12 V-sourced sensors or switches via simple series resistors. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC-series inputs or small LED indicators directly. |
| Power Dissipation | 500 mW max (SO14), derates 10.1 mW/K above 100 °C - enables thermal design margin in sealed junction box environments. |
Pinout & Package
74HC20D-Q100 uses the SOT108-1 (SO14) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 1C, 1D | Gate 1 inputs | Four logic inputs for first NAND gate; clamp diodes allow safe biasing above VCC with external resistor. |
| 1Y | Gate 1 output | Inverted AND of inputs 1A–1D; drives HC-compatible loads up to ±4 mA at VCC = 4.5 V. |
| 2A, 2B, 2C, 2D | Gate 2 inputs | Four independent logic inputs for second NAND gate; electrically isolated from Gate 1. |
| 2Y | Gate 2 output | Independent inverted AND output; supports concurrent logic evaluation without shared timing path. |
| GND (Pin 7) | Ground reference | Primary 0 V return for all internal circuitry and output sinks; must be low-impedance for noise immunity. |
| VCC (Pin 14) | Supply voltage | CMOS core and I/O supply; decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
| n.c. (Pins 3, 11) | No-connect terminals | Internally unconnected; must remain floating - no PCB trace or solder mask relief required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including lifetime reliability stress testing. |
| Input clamp diode protection | Enables direct connection to 12 V sensor outputs using only a 10 kΩ series resistor - eliminates external clamping components. |
| High noise immunity | Typical VIH = 3.15 V and VIL = 1.35 V at VCC = 4.5 V - provides >1.8 V noise margin against coupled transients in vehicle harnesses. |
| Low dynamic power | CPD = 22 pF - limits switching power to <100 μW at 1 MHz/5 V, reducing thermal load in dense ECUs. |
| JEDEC-compliant I/O levels | Fully compatible with TTL and 74HC families - allows mixed-logic-system interoperability without translators. |
Applications
| Engine Control Unit Logic | Body Control Module Reset Coordination |
|---|---|
|
Use Scenario: Combining cam/crank sensor readiness, oil pressure OK, and coolant temp valid signals before enabling fuel injection sequence. IC Role / Device Role / Timing Role: Dual NAND gate performs synchronous validation of four parallel status bits per engine cycle phase.

| ADAS Camera Power Sequencing | Electric Power Steering Diagnostic Logic |
|

IC Role / Device Role / Timing Role: First NAND verifies four thermal zones; second NAND gates camera enable based on system watchdog timeout. Use Value: Prevents sensor damage from premature power-up - replaces 3x discrete logic ICs with single SO14 footprint and zero firmware overhead. |
Use Scenario: Detecting simultaneous failure of torque sensor, motor phase current monitor, and steering angle validity flags. IC Role / Device Role / Timing Role: Each NAND evaluates four fault inputs; outputs feed OR logic to trigger EPS fail-safe mode.

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 |
|---|---|---|---|
| 74HC20PW-Q100 | TSSOP14 package (SOT402-1), 4.4 mm body width, 0.65 mm pitch - lower profile but higher thermal resistance (7.3 mW/K derating above 81 °C). | Better suited for space-constrained PCBs where height <1.2 mm is mandatory; less optimal for high-ambient under-hood locations. | Select when board area is constrained and thermal environment remains ≤85 °C - verify reflow profile compatibility with fine-pitch leads. |
| SN74HC20QPWRQ1 | Texas Instruments variant; identical logic function and AEC-Q100 Grade 1 rating, but VIH/VIL thresholds differ slightly (VIH min = 3.5 V at VCC = 4.5 V vs. Nexperia's 3.15 V). | Marginally reduced noise immunity in noisy 12 V domains; requires verification of input signal rise/fall rates per TI's recommended 83 ns/V spec. | Prefer when TI ecosystem alignment or existing TI-based BOM simplification is prioritized - confirm VIH/VIL margins match actual sensor output swing. |
Compared with 74HC20PW-Q100 and SN74HC20QPWRQ1, the 74HC20D-Q100 offers superior thermal derating margin for under-hood use, tighter input threshold consistency across temperature, and broader legacy design support in European automotive Tier 1s.

FAQ
Is 74HC20D-Q100 pin-compatible with non-automotive 74HC20 variants?
Yes - the SO14 pinout matches standard 74HC20 devices (e.g., 74HC20N, 74HC20D), including identical pin assignments for inputs, outputs, VCC, GND, and n.c. terminals. However, only the Q100 version guarantees AEC-Q100 Grade 1 qualification, extended temperature operation, and automotive-grade traceability.
Can 74HC20D-Q100 drive LEDs directly?
Yes - at VCC = 5.0 V, it sources up to 4.0 mA (VOH ≥ 3.98 V) and sinks up to 4.0 mA (VOL ≤ 0.26 V), sufficient for low-current indicator LEDs (e.g., 2 mA @ 2.0 V forward voltage). Use a series resistor ≥1.2 kΩ for 5 V supply; avoid continuous DC drive above 3 mA to maintain output voltage margin.
What is the maximum clock frequency supported by 74HC20D-Q100?
It is a combinational logic device with no internal clock - propagation delay defines maximum usable toggle rate. With tpd = 8 ns (VCC = 6.0 V), the theoretical maximum toggle frequency is ~62.5 MHz, but practical use in synchronous systems is limited by input transition rates (Δt/ΔV ≤ 83 ns/V at VCC = 6.0 V) and load capacitance.
Does 74HC20D-Q100 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied HIGH or LOW to prevent floating states that cause increased ICC and potential oscillation. The internal CMOS structure has no weak pull-ups; leaving an input open risks undefined output and elevated power consumption due to partial conduction in the input stage.
