Product details

Overview

74HC02PW-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and propagation delay as low as 7 ns at VCC = 6.0 V. It serves as a fundamental logic building block in automotive body control modules, powertrain interface circuits, and infotainment system signal conditioning.

For engineers reviewing the 74HC02PW-Q100 datasheet, 74HC02PW-Q100 pinout, 74HC02PW-Q100 application, or 74HC02PW-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS), guaranteed operation across extended automotive temperature range, output drive capability (±25 mA), and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

This device implements four independent 2-input NOR gates using silicon-gate CMOS technology, enabling high noise immunity and low static power consumption. Each gate features integrated input clamp diodes, allowing safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

The logic function follows standard Boolean NOR behavior: output is HIGH only when both inputs are LOW; otherwise, output is LOW. Input thresholds are referenced to VCC (VIH ≥ 70% VCC, VIL ≤ 30% VCC), ensuring robust switching margins across the full 2.0–6.0 V supply range.

Key Specifications

Supply Voltage Range	2.0 V to 6.0 V - supports wide-rail automotive and industrial systems without level-shifting
Propagation Delay	7 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-20 MHz synchronous logic paths
Output Drive	±25 mA - sufficient to directly drive LEDs, small MOSFET gates, or fan-out to ≥10 74HC loads
Operating Temperature	-40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and transmission control units

7	2Y	Output of Gate 2 - active-low NOR result of inputs 2A and 2B
8	4A	Input A of Gate 4 - one of two inputs defining Gate 4's logic state
9	2A	Input A of Gate 2 - paired with 2B to form second NOR function
10	3Y	Output of Gate 3 - active-low NOR result of inputs 3A and 3B
11	2B	Input B of Gate 2 - completes Gate 2's dual-input structure
12	3B	Input B of Gate 3 - paired with 3A to define Gate 3's output
13	GND	Ground reference - low-impedance return path for all internal circuitry and outputs
14	3A	Input A of Gate 3 - primary input for third NOR gate

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing
Input clamp diodes	Enables overvoltage-tolerant interfacing (e.g., 12 V sensor signals into 5 V logic) with simple series resistors
Low dynamic power dissipation	CPD = 22 pF - minimizes switching current in high-frequency clock distribution or address decoding
High noise immunity	Typical noise margin > 40% of VCC - rejects EMI-induced glitches in electrically noisy vehicle environments
Side-wettable flanks (SWF)	Facilitates automated optical inspection (AOI) of solder joints on bottom-side terminations in TSSOP package

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT02PW-Q100	TTL-compatible inputs (VIH = 2.0 V min), fixed 4.5–5.5 V supply range	Better suited for mixed-logic systems with legacy 5 V TTL peripherals	Select when interfacing to 5 V TTL outputs; not recommended for 3.3 V-only or wide-supply designs
SN74LVC02APWRE4	Lower VCC range (1.65–5.5 V), higher speed (tpd = 4.5 ns @ 3.3 V), non-automotive grade	Lacks AEC-Q100 qualification; suitable for industrial/commercial but not automotive safety-critical use	Use only in non-automotive applications requiring faster timing or lower voltage operation

Compared with 74HC02PW-Q100, the 74HCT02PW-Q100 trades supply flexibility for TTL interoperability, while the SN74LVC02APWRE4 offers superior speed and voltage scalability at the cost of automotive qualification - making the original part uniquely balanced for AEC-Q100-compliant 2–6 V logic integration.

FAQ

Is 74HC02PW-Q100 pin-compatible with standard 74HC02 in SO14 or DHVQFN packages?

Yes - all variants (74HC02D-Q100, 74HC02PW-Q100, 74HC02BQ-Q100) share identical pin functions and logic behavior. Only physical package dimensions and thermal characteristics differ; PCB layout must match TSSOP14 (SOT402-1) footprint, not SO14 or DHVQFN.

Can this device safely interface with 12 V sensor signals in automotive applications?

Yes - its integrated input clamp diodes allow connection of 12 V signals through a current-limiting resistor (e.g., 10 kΩ), clamping excess voltage to VCC + 0.5 V. This eliminates external protection components while maintaining logic integrity across -40 °C to +125 °C.

What is the maximum output current per pin, and how does it vary with temperature?

The absolute maximum output current is ±25 mA per pin, specified over the full -40 °C to +125 °C range. DC output drive remains stable within datasheet limits; however, total package power dissipation derates linearly above +81 °C (7.3 mW/K) to maintain junction temperature safety.

Does this part support mixed-voltage operation, such as 3.3 V logic interfacing with 5 V peripherals?

No - it operates from a single VCC rail (2.0–6.0 V). For mixed-voltage systems, level translation is required. The 74HCT02PW-Q100 variant supports TTL-level inputs at 5 V, but both variants require matched VCC for proper output voltage swing and noise margin.
