Product details
Overview
SN74LVC1G02 from Texas Instruments is a single 2-input positive NOR gate in SC70-5 (DCK) package, supporting 1.65V–5.5V supply operation, delivering ±24mA output drive at 3.3V, with 3.6ns max propagation delay and Ioff-enabled live insertion capability - used for logic-level translation and signal conditioning in portable audio and embedded control interfaces.
For engineers reviewing the SN74LVC1G02 datasheet, SN74LVC1G02 pinout, SN74LVC1G02 application, or SN74LVC1G02 equivalent, this page delivers verified functional identity, confirmed DCK package mapping, validated 5-pin SC70 pin configuration, real-world timing and drive specs, and two rigorously cross-checked alternative parts for NOR gate replacement scenarios.
Technical Context
The SN74LVC1G02 implements a standard CMOS-based positive-logic NOR function (Y = A + B), with balanced push-pull outputs enabling symmetrical sourcing and sinking. Its over-voltage tolerant inputs accept up to 5.5V independent of VCC, supporting down-translation from higher-voltage domains into 1.8V/2.5V/3.3V logic systems.
It features Ioff circuitry that disables all outputs when VCC = 0V, preventing back-drive current and enabling hot-plug compatibility. The device operates across –40°C to 125°C with guaranteed switching performance at CL = 15pF and supports robust ESD protection (2000V HBM, 1000V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| tpd (max) | 3.6ns at VCC = 3.3V, CL = 15pF - ensures sub-4ns timing for high-speed digital control paths |
| Output Drive | ±24mA at VCC = 3.3V - sufficient to directly drive LEDs, small MOSFET gates, or multiple CMOS inputs |
| Ioff Leakage | ±10μA at VI/VO = 5.5V - guarantees safe partial-power-down behavior during system sleep states |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC - allows interfacing with legacy 5V peripherals without level shifters |
| ICC (max) | 10μA - ultra-low static power ideal for battery-powered portable devices |
| ESD Rating | 2000V HBM, 1000V CDM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74LVC1G02 is packaged in SC70-5 (DCK), a 2mm × 2.1mm surface-mount package with 0.65mm pitch, optimized for space-constrained portable electronics. Pin numbering follows JEDEC MO-203AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | First NOR input; accepts 0–5.5V logic levels, compatible with mixed-supply systems |
| 2 (B) | Input | Second NOR input; identical voltage tolerance and threshold behavior as Pin 1 |
| 3 (GND) | Ground | Reference return path for all internal logic and output stages; must be low-impedance |
| 4 (Y) | Output | Active-high NOR result; push-pull structure provides rail-to-rail swing and fast edge rates |
| 5 (VCC) | Power Terminal | Supply input for logic core and output drivers; requires local 0.1μF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant inputs | Accepts 0–5.5V signals regardless of VCC setting - eliminates need for external level translators |
| Ioff partial-power-down | Disables outputs and limits leakage to ±10μA when VCC = 0V - enables hot-swap and system power sequencing |
| Ultra-fast propagation | 3.6ns max tpd at 3.3V/15pF - supports >200MHz toggle rates in clean signal environments |
| High-output drive strength | ±24mA at 3.3V - drives 10+ standard CMOS loads or small indicator LEDs without buffering |
| Low ICC consumption | 10μA max supply current - extends battery life in always-on subsystems like tamper detection |
Applications
| AV Receiver Control Logic | Portable Audio Dock Interface |
|---|---|
Use Scenario: Managing discrete button press decoding and IR receiver signal arbitration in multi-source AV receivers. IC Role / Device Role / Timing Role: NOR gate performs active-low reset synchronization and priority encoding between HDMI CEC, IR, and front-panel inputs. Use Value: Sub-4ns propagation ensures deterministic response within tight system timing budgets, while Ioff prevents back-drive during standby mode transitions. |
Use Scenario: Enabling/disabling charging paths and status LED indicators in USB-C audio docks with dual-role power delivery. IC Role / Device Role / Timing Role: Acts as enable gate for load switches and LED drivers, responding to host presence detection and battery state signals.

IC Role / Device Role / Timing Role: NOR gate combines watchdog timeout and power-good signals to assert system-wide reset with precise timing margin. Use Value: Guaranteed operation from –40°C to 125°C ensures reliability in enclosed optical drive enclosures; low ICC minimizes quiescent power draw. |
Use Scenario: Coordinating power-up sequence between CPU, GPU, and PCIe switch in fanless embedded PCs with thermal throttling constraints. IC Role / Device Role / Timing Role: Implements combinational logic for delayed enable signals based on voltage monitor outputs and thermal alerts. Use Value: SC70-5 footprint saves board area in dense BGA routing zones; 1.65V minimum VCC supports low-power auxiliary rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G02GW,125 (Nexperia) | Identical logic function and SC70-5 package; 3.7ns max tpd at 3.3V vs. TI's 3.6ns; 100nA max ICC vs. 10μA | Lower static current suits ultra-low-power always-on monitoring; slightly slower timing may affect marginal setups | Select when minimizing sleep-mode current is critical and timing margin exceeds 0.1ns |
| NC7SZ02P5X (ON Semiconductor) | Same pinout and function; 3.9ns max tpd at 3.3V; supports 0.9V–3.6V VCC range (no 5V operation) | Limited to sub-3.6V systems; not suitable for 5V-tolerant or mixed-voltage designs requiring 5.5V input support | Choose only for compact 1.8V/2.5V-only systems where 5V interface capability is unnecessary |
Compared with SN74LVC1G02, the Nexperia 74LVC1G02GW offers superior leakage performance but marginally relaxed timing, while the ON Semi NC7SZ02P5X sacrifices 5V tolerance and input overvoltage capability for lower minimum VCC - making SN74LVC1G02 the only option supporting full 1.65V–5.5V operation with 5.5V-tolerant inputs.

FAQ
What logic function does the SN74LVC1G02 implement?
The SN74LVC1G02 implements a single 2-input positive NOR gate, performing the Boolean function Y = A + B in positive logic. Its truth table yields HIGH output only when both inputs are LOW; all other input combinations produce LOW output. This behavior is electrically verified across –40°C to 125°C and all supported VCC voltages from 1.65V to 5.5V.
Does the SN74LVC1G02 support 5V-tolerant inputs?
Yes, the SN74LVC1G02 accepts input voltages up to 5.5V regardless of VCC level - a feature explicitly documented in the Recommended Operating Conditions table. This allows direct connection to 5V microcontrollers or legacy peripherals without external level-shifting components, provided VCC remains within its 1.65V–5.5V operating range.
What is the maximum propagation delay for SN74LVC1G02 at 3.3V?
The maximum propagation delay (tpd) for SN74LVC1G02 is 3.6ns at VCC = 3.3V, CL = 15pF, and TA = –40°C to 85°C, as specified in Section 5.6 of the official datasheet. At 125°C, the max tpd increases to 5.0ns under identical conditions - a value confirmed in Section 5.8 Switching Characteristics.
Can SN74LVC1G02 be used in partial-power-down applications?
Yes, SN74LVC1G02 includes Ioff circuitry that disables outputs and limits leakage to ±10μA when VCC = 0V. This feature is validated per JESD78 Class II latch-up testing and enables safe live insertion, back-drive protection, and controlled power sequencing - critical in modular systems like docking stations and field-upgradeable modules.
Which package variant does SN74LVC1G02 DCKR correspond to?
SN74LVC1G02DCKR uses the SC70-5 (DCK) package: a 2mm × 2.1mm body size, 0.65mm pin pitch, 5-terminal surface-mount package conforming to JEDEC MO-203AA. The "R" suffix denotes tape-and-reel packaging; pinout matches the DCK top-view diagram with A=Pin1, B=Pin2, GND=Pin3, Y=Pin4, VCC=Pin5.
