Product details
Overview
74LVC2G32GT,115 from Nexperia is a dual 2-input OR gate logic IC in XSON8 package (SOT833-1), operating from 1.65 V to 5.5 V supply, featuring IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and 5 V-tolerant I/O in mixed-voltage systems. It enables level translation between 3.3 V and 5 V domains in compact space-constrained interfaces.
For engineers reviewing the 74LVC2G32GT,115 datasheet, 74LVC2G32GT,115 pinout, 74LVC2G32GT,115 application, or 74LVC2G32GT,115 equivalent, this device serves as a low-power, high-noise-immunity dual OR gate for voltage-level interfacing, bus arbitration, and signal combining in industrial control, portable electronics, and embedded system I/O expansion.
Technical Context
The 74LVC2G32GT implements two independent OR logic functions with Schmitt-trigger inputs that accept slow-rising/falling signals and tolerate input overvoltage up to 5.5 V. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It supports full rail-to-rail operation across 1.65–5.5 V, delivers ±24 mA output drive at 3.0 V, and maintains guaranteed propagation delay ≤4.0 ns (VCC = 4.5–5.5 V) over –40 °C to +125 °C. Input thresholds scale with VCC per JEDEC standards JESD8-7/8-5/8C/36.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input OR gate - enables parallel signal combination without interaction between channels. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. |
| IOFF Protection | Active at VCC = 0 V - prevents damaging back-current flow during hot-insertion or partial power-down sequences. |
| Propagation Delay | ≤4.0 ns max (VCC = 4.5–5.5 V, –40 °C to +125 °C) - ensures timing-critical combinational logic integrity in high-speed control paths. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads without buffering. |
| Input Thresholds | VIL ≤0.3×VCC, VIH ≥0.7×VCC (VCC = 4.5–5.5 V) - provides robust noise margin and compatibility with TTL and CMOS logic levels. |
| Operating Temperature | –40 °C to +125 °C - qualified for extended industrial and under-hood automotive auxiliary applications. |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1); no leads; 8 terminals; body dimensions 1.0 mm × 1.95 mm × 0.5 mm; thermal pad not present; pin 1 index located on lower-left corner below marking "V32".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A | Input A of Gate 1 / Gate 2 | Primary OR operand inputs; Schmitt-triggered for noise rejection and slow-edge tolerance. |
| 1B, 2B | Input B of Gate 1 / Gate 2 | Secondary OR operand inputs; identical electrical characteristics to 1A/2A pins. |
| 1Y, 2Y | Output Y of Gate 1 / Gate 2 | CMOS push-pull outputs; 5 V tolerant in power-down mode; support IOFF isolation. |
| GND | Ground reference | 0 V return path for all internal circuitry and output sinks; must be low-impedance for noise control. |
| VCC | Positive supply | Single supply rail powering both gates; IOFF function activates only when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V operation - eliminates need for external level shifters in multi-rail systems. |
| Overvoltage-tolerant inputs | Withstand up to 5.5 V regardless of VCC - enables safe connection to higher-voltage buses without clamping diodes. |
| IOFF partial power-down | Outputs disabled with leakage <±2 μA when VCC = 0 V - prevents backfeed in hot-swap or battery-backed subsystems. |
| Schmitt-trigger inputs | Hysteresis ≥0.1×VCC - rejects noise on long traces or unshielded lines in industrial environments. |
| High ESD robustness | HBM >2000 V, CDM >1000 V - reduces field failure risk during handling and board assembly. |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
|
Use Scenario: Combining fault signals from multiple temperature, pressure, and motion sensors into a single alert line feeding a microcontroller interrupt pin. IC Role / Device Role / Timing Role: Dual OR gate performing wired-OR aggregation with deterministic propagation delay (<4 ns) and no added latency jitter. Use Value: Reduces PCB footprint versus discrete diode-OR solutions while guaranteeing noise-immune signal integrity across –40 °C to +125 °C ambient. |
Use Scenario: Enabling system power-up sequence where multiple enable signals (e.g., battery OK, charger ready, thermal OK) must all be HIGH before releasing main DC-DC converter EN pin. IC Role / Device Role / Timing Role: Logic combiner implementing "any one fault → disable" behavior using OR inversion via external inverter or firmware polling. Use Value: Leverages IOFF to isolate downstream circuitry during brown-out or battery removal, preventing backfeed into powered-off sections. |
| USB-C Port Controller Support Logic | Automotive Body Control Module I/O Expansion |
|
Use Scenario: Merging USB-C CC line detection status and VBUS presence signals to generate a unified "port active" flag for host controller. IC Role / Device Role / Timing Role: Level-translating OR gate accepting 5 V CC-line inputs and 3.3 V VBUS sense, outputting 3.3 V-compatible logic to MCU GPIO.

Use Scenario: Adding programmable OR logic to legacy BCM designs where dedicated MCU GPIOs are exhausted but simple wake-up or alarm combination is required. IC Role / Device Role / Timing Role: Standalone combinational logic block interfacing with 5 V sensor outputs and 3.3 V MCU inputs in CAN/LIN gateway modules. Use Value: Qualified to –40 °C to +125 °C and compliant with JEDEC JESD8C (2.7–3.6 V), meeting automotive under-hood auxiliary logic requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G32DBVR | TSSOP8 (SOT23-8) package; 3.0 mm body width; 0.65 mm pitch; higher thermal resistance (RθJA = 213 K/W vs. 250 K/W for XSON8). | Better manual solderability and test probe access; less suitable for ultra-dense layouts than XSON8. | Select when board assembly uses standard reflow profiles optimized for TSSOP, or when thermal margin exceeds 100 mW dissipation. |
| 74AUP2G32GT,115 | Lower static current (ICC ≤ 0.9 μA typical); wider VCC range (0.8–3.6 V); slower max tpd (7.3 ns at 3.3 V); no 5 V input tolerance. | Optimized for battery-powered sub-1 V logic; incompatible with 5 V signal sources without external clamping. | Select only for ultra-low-power, single-supply (≤3.6 V) systems where 5 V tolerance is unnecessary and speed <7 ns is acceptable. |
Compared with SN74LVC2G32DBVR, the 74LVC2G32GT,115 offers superior board-area efficiency and thermal performance in high-density designs; compared with 74AUP2G32GT,115, it trades higher quiescent current for essential 5 V input tolerance and faster switching in mixed-voltage industrial interfaces.

FAQ
Does the 74LVC2G32GT,115 support true bidirectional level translation?
No. The 74LVC2G32GT,115 is a unidirectional OR gate with 5 V-tolerant inputs and CMOS outputs referenced to VCC. It performs voltage-level *acceptance* (e.g., 5 V inputs into 3.3 V system) but does not translate output voltage beyond VCC. True bidirectional translation requires dedicated level-shifter ICs like NXSL1T240.
Can the 74LVC2G32GT,115 be used with VCC = 1.8 V while driving 3.3 V-tolerant inputs?
Yes. At VCC = 1.8 V, VOH ≥1.62 V (0.9×VCC) and VOL ≤0.18 V meet the VIH/VIL thresholds of 3.3 V LVC devices (VIH ≥2.0 V, VIL ≤0.8 V). However, fanout is limited to ≤2 LVC loads due to reduced drive strength; verify with actual load capacitance and timing margins.
What is the maximum capacitive load the 74LVC2G32GT,115 can drive at 10 MHz with VCC = 3.3 V?
At VCC = 3.3 V and f = 10 MHz, the dynamic power limit (Ptot ≤ 250 mW) and CPD = 14 pF/gate allow ≤150 pF total load capacitance per output. This includes PCB trace, probe, and input capacitance of driven devices. Exceeding this risks excessive rise/fall time degradation and localized heating.
Is the GND pin electrically isolated from the die attach pad in the SOT833-1 package?
Yes. The SOT833-1 (XSON8) package has no thermal pad; all eight terminals are signal/power connections. GND (pin 4) is the sole ground reference and must be connected to the system ground plane with low-inductance routing to ensure stable noise immunity and IOFF functionality.
