Product details
Overview
74HCT1G02GW,165 from Nexperia is a single 2-input NOR gate logic IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, 24 ns typical propagation delay at 50 pF load, and TSSOP5 (SOT353-1) 5-pin surface-mount package. It delivers symmetrical output drive, high noise immunity, and operates across -40 °C to +125 °C for industrial control signal conditioning.
For engineers reviewing the 74HCT1G02GW,165 datasheet, 74HCT1G02GW,165 pinout, 74HCT1G02GW,165 application, or 74HCT1G02GW,165 equivalent, this device serves as a compact, temperature-resilient logic gate for level-shifting, enable/disable control, and combinational logic in space-constrained embedded systems.
Technical Context
The 74HCT1G02GW,165 implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with TTL-level input compatibility-VIH(min) = 2.0 V and VIL(max) = 0.8 V at VCC = 4.5–5.5 V-enabling direct interfacing with legacy 5 V microcontrollers and peripheral drivers. Its CMOS output stage provides rail-to-rail swing and ±2.0 mA drive capability.
Designed for robust industrial use, it features input clamp diodes supporting current-limiting resistor interfacing to voltages exceeding VCC, latch-up immunity >100 mA per JESD78 Class II Level B, and ESD protection rated at HBM >2000 V and CDM >1000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate (Y = NOT(A OR B)), enabling basic combinational logic and active-low enable control |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V TTL/CMOS system rails without level translation |
| Propagation Delay | 24 ns typical (A/B to Y, VCC = 4.5 V, CL = 50 pF) - supports reliable timing in sub-40 MHz digital control paths |
| Output Drive | ±2.0 mA - sufficient to directly drive LED indicators, small logic loads, or subsequent gate inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor control, and industrial automation environments |
| Input Thresholds | VIH(min) = 2.0 V, VIL(max) = 0.8 V - ensures compatibility with 5 V TTL outputs and noise margin >0.4 V |
| Power Dissipation | CPD = 19 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi) for low-power design |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Second logic input; accepts TTL-level signals; includes internal clamp diode to VCC/GND |
| 2 (A) | Data input | Primary logic input; electrically identical to Pin 1; used for dual-input NOR evaluation |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance for noise immunity |
| 4 (Y) | Data output | Inverted OR result; CMOS push-pull output capable of sourcing/sinking ±2.0 mA |
| 5 (VCC) | Supply voltage | Positive supply rail (4.5–5.5 V); decoupling capacitor required within 10 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables plug-in replacement of legacy 74LS02 without redesign; eliminates external level shifters |
| Symmetrical output impedance | Ensures matched rise/fall times (tpLH ≈ tpHL), reducing signal distortion in timing-critical paths |
| Clamp diodes on all inputs | Allows safe interface to voltages > VCC using series resistors-critical for mixed-voltage board designs |
| High noise immunity | Guaranteed 0.4 V noise margin at VCC = 5 V, improving reliability in electrically noisy motor or relay environments |
| Wide temperature range | Validated operation from -40 °C to +125 °C supports deployment in uncontrolled industrial enclosures |
Applications
| Industrial PLC Input Conditioning | Microcontroller Peripheral Enable Control |
|---|---|
Use Scenario: Isolating and debouncing mechanical switch inputs before feeding into a PLC CPU module. IC Role / Device Role / Timing Role: NOR gate configured as an active-low OR combiner to aggregate multiple limit switch signals into one interrupt line. Use Value: Eliminates need for discrete diodes/resistors; leverages built-in clamp diodes and 125 °C rating for cabinet-mounted operation. |
Use Scenario: Enabling/disabling SPI flash memory or UART transceivers based on system power state. IC Role / Device Role / Timing Role: Logic-level translator and gating element that asserts /CS or /EN only when both MCU GPIO and power-good signals are asserted. Use Value: Reduces BOM count by replacing two discrete gates; TTL input thresholds match 5 V MCU I/O without pull-ups. |
| Motor Driver Fault Signal Aggregation | Legacy System Bus Arbitration |
Use Scenario: Combining overcurrent, overtemperature, and undervoltage fault flags from a 3-phase inverter driver IC. IC Role / Device Role / Timing Role: Active-low fault aggregator: output goes LOW if any input fault is asserted, triggering system shutdown. Use Value: Propagation delay <27 ns ensures fast fault response; ±2 mA drive directly interfaces to optocoupler LED inputs. |
Use Scenario: Resolving bus contention between two 8051-family microcontrollers sharing a common address/data bus. IC Role / Device Role / Timing Role: Bus grant arbitration logic: NOR output enables one controller's bus drivers only when the other is inactive. Use Value: Matches 5 V TTL timing budgets; symmetrical delays prevent metastability during handoff transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G02GV,125 | Same logic function and electrical specs, but in SC-74A (SOT753) package - 3.1 mm × 1.7 mm vs. TSSOP5's 2.2 mm × 1.35 mm | Lower profile (1.1 mm max height) and larger pad spacing aid manual rework; less suitable for ultra-dense layouts | Select when board assembly uses wave soldering or requires larger solder joints for reliability validation |
| SN74LVC1G02DBVR | Wider VCC range (1.65–5.5 V), lower ICC (<1 μA), but VIH/VIL tied to VCC - not TTL-compatible at 5 V | Requires external pull-up or level-shifting for legacy 5 V TTL sources; better suited for mixed-voltage battery-powered systems | Choose only if supply flexibility or ultra-low quiescent current outweighs need for direct TTL interoperability |
Compared with 74HCT1G02GV,125, the 74HCT1G02GW,165 offers superior board-area efficiency and thermal performance in TSSOP5; versus SN74LVC1G02DBVR, it guarantees seamless integration with existing 5 V TTL infrastructure without signal conditioning.

FAQ
Is the 74HCT1G02GW,165 pin-compatible with the 74HC1G02GW,165?
Yes-both share identical TSSOP5 (SOT353-1) pinout and terminal assignment (A, B, GND, Y, VCC). However, the 74HCT1G02GW,165 uses TTL input thresholds (VIH = 2.0 V min), while the 74HC1G02GW,165 uses CMOS thresholds (VIH = 3.15 V min at VCC = 4.5 V), making them electrically non-interchangeable without verifying source logic levels.
Can the 74HCT1G02GW,165 operate at 3.3 V supply?
No-it is not characterized or guaranteed for 3.3 V operation. The 74HCT1G02 series is specified only for 4.5 V to 5.5 V supply; at 3.3 V, input thresholds become undefined and propagation delay increases significantly. For 3.3 V systems, use the 74LVC1G02 or 74AUP1G02 instead.
What is the maximum capacitive load the 74HCT1G02GW,165 can drive reliably?
The device is characterized up to 50 pF load capacitance with guaranteed 27 ns max propagation delay at VCC = 4.5 V. Driving >50 pF increases delay nonlinearly and may cause marginal timing; for loads >75 pF, add a series resistor (22–47 Ω) near the output to damp ringing and maintain signal integrity.
Does the 74HCT1G02GW,165 require external pull-up or pull-down resistors on unused inputs?
Unused inputs must be terminated-either tied to VCC or GND-to prevent floating states that cause excessive ICC and potential oscillation. Internal clamp diodes do not eliminate this requirement; leaving inputs open violates recommended operating conditions and risks erratic behavior or increased power consumption.
