Product details
Overview
74AHCT1G02GW,125 from Nexperia is a single 2-input NOR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5-pin TSSOP5 (SOT353-1) package, −40 °C to +125 °C operating range, and propagation delay of 3.5–7.0 ns (CL = 15–50 pF, VCC = 4.5–5.5 V). It serves as a level-translating combinational logic element in mixed-voltage digital control paths.
For engineers reviewing the 74AHCT1G02GW,125 datasheet, 74AHCT1G02GW,125 pinout, 74AHCT1G02GW,125 application, or 74AHCT1G02GW,125 equivalent, key selection criteria include TTL-level input compatibility, overvoltage-tolerant inputs up to 5.5 V, symmetrical output drive (±8 mA), industrial temperature support, and low dynamic power dissipation (CPD = 19 pF).
Technical Context
This device implements a single 2-input NOR function with true complementary CMOS output stage, delivering balanced tPLH/tPHL propagation delays and symmetrical output impedance. Its TTL-compatible input thresholds enable direct interfacing with legacy 5 V logic families while operating from 4.5–5.5 V supply.
The input structure supports overvoltage tolerance up to 5.5 V independent of VCC, allowing safe operation in mixed-supply systems where input signals may exceed the local rail. Static and dynamic characteristics are fully specified across −40 °C to +125 °C, with latch-up immunity exceeding 100 mA per JESD78 Class II Level A.

| Industrial temperature range | Validated operation from −40 °C to +125 °C supports deployment in automotive engine control units and industrial PLCs |
| Low dynamic power dissipation | CPD = 19 pF enables <1 μW/MHz static + dynamic power at 5 V - critical for battery-backed or thermally constrained modules |
Applications
| Motor Control Logic | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Combining fault signals (e.g., overcurrent, overtemperature, stall detection) in a BLDC motor driver to generate a unified shutdown command. IC Role / Device Role / Timing Role: NOR gate performs active-low OR logic on multiple fault inputs; output directly drives enable/disable input of gate driver IC. Use Value: Eliminates need for discrete diodes or additional logic stages; propagation delay <7 ns ensures real-time fault response within safety-critical timing budgets. |
Use Scenario: Converting open-collector sensor outputs (e.g., Hall-effect switches, limit switches) into clean CMOS-compatible active-high enable signals for ADC sampling control. IC Role / Device Role / Timing Role: Inverts and wires together multiple sensor status lines; acts as asynchronous event combiner before microcontroller interrupt input. Use Value: Overvoltage-tolerant inputs accept 5 V sensor outputs while operating from 5 V rail; symmetrical drive ensures fast edge integrity into MCU GPIO. |
| Power Sequencing Supervisor | Legacy System Bus Glue Logic |
|
Use Scenario: Monitoring multiple DC/DC converter OK signals to assert a global "power good" signal only when all rails are stable. IC Role / Device Role / Timing Role: NOR gate implements negative-logic AND function (via De Morgan's law); output asserts low only when all inputs are low (i.e., all converters OK). Use Value: Single-gate solution reduces board area vs. multi-input AND IC; −40 °C to +125 °C rating matches power supply thermal profile. |
Use Scenario: Adapting address decode logic between older 5 V ISA bus peripherals and newer 5 V microcontroller address spaces with partial decoding. IC Role / Device Role / Timing Role: Implements address-range masking and chip-select generation using fixed address bits and control strobes. Use Value: TTL input thresholds guarantee reliable recognition of ISA bus timing edges; 3.5 ns typical tpd preserves setup/hold timing margins in 8 MHz bus cycles. |
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 |
|---|---|---|---|
| 74AHCT1G02GV,125 | Same logic function and electrical specs, but in SC-74A (SOT753) package - 3.1 mm × 1.7 mm body, 0.95 mm pitch, no exposed pad | Preferred for manual assembly or wave soldering due to larger pad spacing and mechanical robustness | Select GV variant when PCB reflow profile lacks fine-pitch capability or when higher mechanical reliability under vibration is required |
| SN74LVC1G02DBVR | CMOS-level inputs (VIH = 2.0 V @ VCC = 3.3 V), wider supply range (1.65–5.5 V), but only rated to +85 °C | Suitable for 3.3 V–5 V mixed systems with less stringent temperature requirements; lacks industrial temp grade | Choose LVC variant only if operating ambient stays ≤+85 °C and supply flexibility outweighs temperature assurance |
Compared with 74AHCT1G02GV,125, the GW variant offers finer pitch and smaller footprint for high-density layouts; versus SN74LVC1G02DBVR, it delivers guaranteed +125 °C operation and superior noise immunity in noisy industrial environments, at the cost of fixed 4.5–5.5 V supply constraint.

FAQ
Is 74AHCT1G02GW,125 compatible with 3.3 V microcontroller outputs?
No - its TTL-level inputs require VIH ≥ 2.0 V, but are only guaranteed functional when VCC = 4.5–5.5 V. A 3.3 V MCU output may not reliably meet the 2.0 V VIH threshold under worst-case conditions (e.g., VCC = 4.5 V, temperature extremes). Use 74AHC1G02GW,125 for CMOS-level compatibility down to 2.0 V supply.
Can this device drive a 50 pF load at 10 MHz without signal degradation?
Yes - with CL = 50 pF and VCC = 5.0 V, propagation delay is ≤9.5 ns and output drive is ±8 mA, ensuring clean edges and <10% overshoot/undershoot. CPD = 19 pF yields dynamic power <1 μW/MHz, confirming suitability for sustained 10 MHz toggle rates in thermally managed designs.
What is the maximum allowable input voltage when VCC = 4.5 V?
The absolute maximum input voltage is +7.0 V per Table 5, but the overvoltage-tolerant design guarantees safe operation up to +5.5 V regardless of VCC. Applying >5.5 V risks permanent damage even if within the ±7.0 V limiting value, as clamping circuits are optimized for ≤5.5 V overvoltage events.
Does this part support hot-swap insertion into a live 5 V backplane?
Yes - overvoltage-tolerant inputs and JESD78 Class II Level A latch-up immunity (>100 mA) allow safe connection to powered systems. However, VCC must be ramped before applying input signals to avoid transient current injection through input protection diodes; follow Nexperia's recommended power sequencing guidelines.
