Product details
Overview
SN74LVC1G02DBVR from Texas Instruments is a single 2-input positive NOR gate in ultra-small X2SON-5 (DPW) package, supporting 1.65V–5.5V supply operation, delivering 3.6ns max propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled live insertion for partial-power-down systems. It performs Y = A + B logic in portable audio docks and SSD power sequencing.
For engineers reviewing the SN74LVC1G02DBVR datasheet, SN74LVC1G02DBVR pinout, SN74LVC1G02DBVR application, or SN74LVC1G02DBVR equivalent, key selection factors include its over-voltage tolerant inputs (up to 5.5V), ultra-low ICC (10μA max), 0.8mm × 0.8mm body size, and guaranteed operation from –40°C to 125°C.
Technical Context
The SN74LVC1G02DBVR implements standard CMOS NOR logic with balanced push-pull outputs capable of sourcing and sinking equal current (±24mA at 3.3V). Its input structure includes over-voltage tolerance and clamp diodes, enabling interoperability across mixed-voltage domains without level shifters.
It features Ioff circuitry that disables all outputs when VCC = 0V, limiting leakage to ±10μA and preventing back-drive during hot-swap or partial-power-down. The device operates across full industrial temperature range (–40°C to 125°C) with guaranteed timing performance down to 1.65V supply.
Key Specifications

Pinout & Package
X2SON-5 (DPW) package: 0.8mm × 0.8mm body, 0.5mm pitch, no exposed thermal pad, compatible with standard reflow profiles and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | First NOR operand; accepts 0–5.5V regardless of VCC; must be terminated to VCC or GND if unused |
| B | Input | Second NOR operand; identical voltage tolerance and termination requirements as Pin A |
| GND | Ground | Reference return path for all internal circuitry and output current sinking |
| Y | Output | Active-low NOR result; push-pull structure provides rail-to-rail swing and fast edge rates |
| VCC | Power Terminal | Positive supply input; powers internal logic and defines VOH/VOL thresholds; requires local 0.1μF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant inputs | Accepts up to 5.5V on A/B pins while VCC = 1.65V–5.5V - eliminates need for external level translators in mixed-supply systems |
| Ioff partial-power-down support | Disables outputs and limits leakage to ±10μA when VCC = 0V - enables safe live insertion and back-drive protection |
| Ultra-small X2SON-5 footprint | 0.64mm² board area (0.8mm × 0.8mm body) - ideal for space-critical applications like wireless headsets and SSD modules |
| Wide temperature operation | Guaranteed functionality from –40°C to 125°C - suitable for automotive infotainment and industrial embedded controllers |

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) | SC-70-5 package (2.0mm × 1.25mm body); 3.7ns tpd at 3.3V; identical electrical specs except slightly higher ICC (15μA max) | Larger footprint; same functional behavior but less suitable for ultra-dense layouts where DPW's 0.64mm² is critical | Choose when SC-70 assembly infrastructure is already in place and board area is not constrained. |
| NC7SZ02P5X (ON Semiconductor) | SOT-353 (SC-70) package; 3.9ns tpd at 3.3V; supports 1.65V–5.5V; Ioff specified at ±20μA (vs. ±10μA for SN74LVC1G02DBVR) | Higher Ioff leakage may impact reliability in deep-sleep modes; otherwise functionally interchangeable in most consumer designs | Prefer for cost-sensitive volume production where minor leakage increase is acceptable and SC-70 is preferred. |
Compared with 74LVC1G02GW,125 and NC7SZ02P5X, the SN74LVC1G02DBVR offers the smallest board footprint (0.64mm²), lowest Ioff leakage (±10μA), and best timing consistency across voltage/temperature - making it optimal for space- and power-constrained portable electronics.

FAQ
What is the maximum operating temperature for the SN74LVC1G02DBVR?
The SN74LVC1G02DBVR is rated for continuous operation from –40°C to +125°C ambient temperature. This specification is validated per JEDEC JESD78 Class II latch-up testing and confirmed across all recommended supply voltages (1.65V–5.5V), making it suitable for under-hood automotive modules and enclosed industrial enclosures where thermal management is limited. The SN74LVC1G02DBVR maintains full timing and DC parameter compliance across this full range.
Does the SN74LVC1G02DBVR require external pull-up or pull-down resistors on its inputs?
No - the SN74LVC1G02DBVR does not require external pull-up or pull-down resistors for normal operation, but all unused inputs must be actively terminated to either VCC or GND to prevent floating states that cause excessive current draw and oscillation. TI explicitly states in the datasheet that "all unused inputs of the device must be held at VCC or GND to establish proper device operation." The SN74LVC1G02DBVR has standard CMOS inputs with no internal biasing.
Can the SN74LVC1G02DBVR interface directly with a 5V microcontroller while powered from 3.3V?
Yes - the SN74LVC1G02DBVR supports over-voltage tolerant inputs up to 5.5V independent of VCC, so it can safely accept 5V logic signals while operating from a 3.3V supply. This eliminates external level-shifting components in mixed-voltage systems. The SN74LVC1G02DBVR's input clamp structure and specified VI = 0–5.5V range ensure robustness without damage or undefined behavior when interfacing with 5V controllers.
What is the purpose of the Ioff feature in the SN74LVC1G02DBVR?
The Ioff feature in the SN74LVC1G02DBVR disables all outputs and limits leakage current to ±10μA when VCC = 0V, enabling safe live insertion, partial-power-down operation, and back-drive protection. This prevents current flow from powered sections into unpowered sections of a system - a critical requirement in hot-pluggable modules and multi-rail power architectures. The SN74LVC1G02DBVR implements this via internal circuitry that isolates the output stage during VCC absence.
Is the SN74LVC1G02DBVR pin-compatible with other packages of the same part number?
No - the SN74LVC1G02DBVR (X2SON-5, DPW) is not pin-compatible with other package variants like DBV (SOT-23), DCK (SC-70), or YZP (DSBGA), as pin assignments differ across packages. For example, Pin 1 is Input A in DPW but Input A in DBV and DCK - however, Pin 3 is GND in DPW/DBV/DCK but NC in DRY/DSF. The SN74LVC1G02DBVR requires its own layout and cannot be substituted without PCB revision.
