Product details
Overview
74HCT1G02GW,125 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 performs basic Boolean NOR logic in signal conditioning, enable/disable control, and bus arbitration circuits within industrial microcontroller peripherals.
For engineers reviewing the 74HCT1G02GW,125 datasheet, 74HCT1G02GW,125 pinout, 74HCT1G02GW,125 application, or 74HCT1G02GW,125 equivalent, this device is selected for level translation between TTL-output sources and CMOS loads, low-power active-low logic combining, and compact board-level combinational control where thermal performance and IEC-compliant ESD robustness are required.
Technical Context
The 74HCT1G02GW,125 implements a single two-input NOR function using silicon-gate CMOS technology with TTL-level input voltage thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL outputs without level shifters. Its symmetrical output drive supports ±2.0 mA output current at VCC = 4.5 V.
Designed for operation across -40 °C to +125 °C, it features clamp diodes on all inputs for overvoltage tolerance, JESD78 Class II latch-up immunity (>100 mA), and HBM ESD protection exceeding 2000 V. Propagation delay variation is minimized by balanced tPLH/tPHL characteristics and low input capacitance (1.5 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate - provides active-low OR output (Y = NOT(A OR B)) for discrete logic control |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage systems |
| Propagation Delay | 24 ns typical (VCC = 4.5 V, CL = 50 pF) - enables reliable timing in sub-40 MHz digital control paths |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees noise-immune recognition of TTL logic levels |
| Output Drive | ±2.0 mA at VCC = 4.5 V - sufficient to drive 10 LS-TTL loads or multiple CMOS inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor control, and industrial ambient environments |

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 |
|---|---|---|---|
| 74LVC1G02GW,125 | Lower VCC range (1.65–5.5 V); CMOS input thresholds; 3.7 ns faster tpd at 3.3 V | Better suited for 3.3 V-only systems; incompatible with 5 V TTL input sources | Select when operating exclusively at 3.3 V and requiring higher speed; avoid for mixed 5 V TTL/CMOS interfaces |
| SN74LVC1G02DBVR | Same logic function; SOT-23-5 package; 1.65–5.5 V supply; CMOS inputs | Larger footprint (SOT-23 vs TSSOP5); no 5 V TTL input compatibility | Choose for legacy SOT-23 board reuse; verify PCB land pattern and thermal derating versus TSSOP5 |
Compared with 74HCT1G02GW,125, the 74LVC1G02GW,125 offers superior speed at 3.3 V but lacks TTL input compatibility, while SN74LVC1G02DBVR trades package miniaturization and thermal performance for broader distributor availability in SOT-23 form factor.

FAQ
What is the maximum clock frequency supported by the 74HCT1G02GW,125?
The 74HCT1G02GW,125 is a combinational logic gate, not a clocked device, so it has no defined clock frequency. Its usable toggle rate is limited by propagation delay and load capacitance: with 50 pF load and 4.5 V supply, maximum reliable switching frequency is approximately 20 MHz, derived from tpd = 24 ns and minimum pulse width constraints per datasheet timing diagrams.
Can the 74HCT1G02GW,125 operate at 3.3 V supply?
No - the 74HCT1G02GW,125 is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, input thresholds become undefined, VOH/VOL margins collapse, and functionality is not guaranteed. For 3.3 V systems, use the pin-compatible 74LVC1G02GW,125 instead.
Does the 74HCT1G02GW,125 require external pull-up or pull-down resistors on inputs?
No - inputs are TTL-compatible with defined VIH/VIL thresholds and include internal clamp diodes. External resistors are unnecessary for normal logic operation. They are only needed if interfacing to voltages exceeding VCC, leveraging the built-in clamps with current limiting per datasheet Section 1.
Is the 74HCT1G02GW,125 automotive-qualified?
No - this part is not AEC-Q100 qualified. While it operates from -40 °C to +125 °C, Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products are unsuitable for safety-critical or life-support applications, including automotive ECUs, ADAS, or powertrain systems.
