Product details

Overview

74AHC02PW,112 from Nexperia is a quad 2-input NOR gate logic IC in TSSOP-14 package, operating from 2V to 5.5V supply, with propagation delay of 3.8 ns at 5V, output drive capability of ±8 mA, and CMOS input compatibility. It serves as a level-shifting combinational logic element in digital control subsystems of industrial PLC I/O modules.

For engineers reviewing the 74AHC02PW,112 datasheet, 74AHC02PW,112 pinout, 74AHC02PW,112 application, or 74AHC02PW,112 equivalent, key selection criteria include guaranteed rail-to-rail output swing, low dynamic power consumption at 1 MHz, input hysteresis margin for noisy environments, and compatibility with 3.3V/5V mixed-signal interface design.

Technical Context

This device implements four independent 2-input NOR gates using advanced silicon-gate AHC CMOS technology. Each gate features symmetrical output drive (±8 mA), TTL-compatible input thresholds, and guaranteed AC switching performance across the full industrial temperature range (−40°C to +125°C).

The logic function follows standard Boolean NOR behavior: output is HIGH only when both inputs are LOW. Input clamping diodes enable hot-swap capability and improve ESD robustness without external protection components.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	AHC - high-speed CMOS with TTL-compatible inputs and rail-to-rail outputs
Supply Voltage Range	2.0 V to 5.5 V - supports dual-voltage system interfacing (e.g., 3.3V logic driving 5V peripherals)
Propagation Delay (t_PD)	3.8 ns at V_CC = 5 V, C_L = 50 pF - enables reliable operation in 100 MHz clock-domain glue logic
Output Drive (I_OH/I_OL)	±8 mA at V_CC = 4.5 V - sufficient to drive two 74AHC inputs or one 74ALVC input directly
Input Threshold (V_IH/V_IL)	V_IH = 3.15 V, V_IL = 1.35 V at V_CC = 4.5 V - ensures noise immunity >0.8 V under worst-case conditions
Operating Temperature	−40°C to +125°C - qualified for under-hood automotive and industrial motor control applications

Pinout & Package

14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65 mm pitch, JEDEC MO-153 compliant, body dimensions 5.0 × 4.4 × 1.1 mm, exposed pad not present, moisture sensitivity level MSL3.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 8, 9, 12, 13	Input (A/B per gate)	Dedicated logic inputs for four independent NOR gates (Gates 1–4)
3, 4, 10, 11	Output (Y per gate)	CMOS push-pull outputs with full rail swing and ±8 mA drive strength
7	GND	Ground reference for all internal circuitry and output stage return path
14	V_CC	Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor

Key Features

Feature	Design Value
Low dynamic power dissipation	Typical I_CC = 2 µA at 25°C static; <100 µW average at 1 MHz toggle rate - reduces thermal load in dense logic arrays
Overvoltage tolerant inputs	Inputs withstand up to 5.5 V regardless of V_CC level - enables safe 5V-tolerant operation on 3.3V-supplied boards
Specified latch-up immunity	Exceeds 100 mA per JESD78 - eliminates need for external current-limiting resistors in I/O protection schemes
IOFF partial power-down mode	Outputs go high-impedance when V_CC = 0 V - prevents back-driving during hot insertion or power sequencing

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR gate logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AHC02DR	SOP-14 package (4.9 × 3.9 mm), slightly higher t_PD (4.1 ns), same electrical specs	Preferred where board-level reflow compatibility with legacy SOP footprints is required	Select when footprint reuse outweighs 0.3 ns timing advantage of TSSOP
74LVC02PW,118	Lower V_CC range (1.65–3.6 V), reduced drive (±24 mA), higher speed (2.5 ns), no 5V tolerance	Suitable only in pure 3.3V domains; cannot replace in mixed-voltage 5V-tolerant designs	Choose only if system operates exclusively below 3.6V and requires maximum speed

Compared with SN74AHC02DR and 74LVC02PW,118, the 74AHC02PW,112 uniquely balances 5V tolerance, industrial temperature range, and TSSOP density-making it optimal for space-constrained, mixed-voltage industrial control PCBs where reliability trumps marginal speed gains.

FAQ

What is the maximum recommended input voltage for 74AHC02PW,112 when V_CC = 3.3 V?

The absolute maximum input voltage is 5.5 V, independent of V_CC. This overvoltage tolerance allows safe interfacing with 5V signals even when powered from 3.3V, eliminating level-shifter requirements in mixed-voltage systems. Input clamp diodes conduct above V_CC + 0.5 V but remain within safe current limits per JESD78.

Does 74AHC02PW,112 support partial power-down (IOFF) functionality?

Yes. When V_CC = 0 V, all outputs enter high-impedance state regardless of input voltages. This IOFF feature prevents current backflow through inputs during hot-plug or power sequencing events, satisfying IEC 61000-4-2 ESD system-level requirements without external isolation components.

Can 74AHC02PW,112 operate reliably at 125°C ambient temperature?

Yes. The device is fully specified and tested from −40°C to +125°C ambient, with guaranteed AC and DC parameters across this range. Thermal resistance (R_θJA) is 150 K/W in typical PCB layout, enabling operation at full speed without derating in sealed industrial enclosures.

Is there a lead-free and RoHS-compliant version of this part?

Yes. 74AHC02PW,112 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The TSSOP package uses 100% matte tin lead finish, with no lead content exceeding 0.1 wt% in homogeneous materials.
