Product details
Overview
74LVC1G32QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive OR gate in SOT25 package, operating from 1.65V to 5.5V with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial-power-down protection. It performs Y = A + B logic in Grade 1 (-40°C to +125°C) environments for voltage-level shifting and signal isolation in automotive control modules.
For engineers reviewing the 74LVC1G32QW5-7 datasheet, 74LVC1G32QW5-7 pinout, 74LVC1G32QW5-7 application, or 74LVC1G32QW5-7 equivalent, key selection criteria include IOFF-enabled power-down safety, 5.5V input tolerance across VCC range, propagation delay ≤6.0ns at 3.3V, and AEC-Q100 qualification for automotive deployment.
Technical Context
This OR gate implements standard positive-logic Boolean function Y = A + B using CMOS technology with push-pull output stage. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and mixed-voltage system interfacing.
Input voltage tolerance up to 5.5V-regardless of VCC level-supports level translation between 1.8V, 2.5V, 3.3V, and 5V domains. Propagation delay is specified from 0.5ns (min) to 6.0ns (max) at 3.3V, with input transition rate support up to 10 ns/V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Positive OR: Y = A + B, implemented with CMOS push-pull output |
| Supply Voltage Range | 1.65V to 5.5V - enables direct use in 1.8V, 2.5V, 3.3V, and 5V systems |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC - allows safe interfacing with higher-voltage controllers |
| IOFF Support | Active output disable during power-down - prevents damaging back-current in partial-power-down modes |
| Output Drive | ±24mA at VCC = 3.0V - sufficient to drive multiple LVC loads or small capacitive traces |
| Propagation Delay | 0.5–6.0ns at VCC = 3.3V - ensures timing predictability in high-speed digital control paths |
| Operating Temperature | -40°C to +125°C (Grade 1) - qualified for under-hood automotive ECUs and industrial controls |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with moisture sensitivity level 1 per J-STD-020 and matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First OR operand input; 5.5V-tolerant, compatible with all supported VCC levels |
| 2 (B) | Data Input | Second OR operand input; identical electrical behavior to Pin 1 |
| 3 (GND) | Ground Reference | Return path for supply and signals; must be low-impedance for noise immunity |
| 4 (Y) | Data Output | OR result output; push-pull structure supports active high/low drive without external pull-ups |
| 5 (VCC) | Supply Voltage | Power rail input; IOFF functionality requires this pin to be at valid logic-low or floating during power-down |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial-Power-Down Protection | Prevents reverse current flow when VCC = 0V while inputs remain active - critical for hot-swap and multi-rail systems |
| 5.5V-Tolerant Inputs | Enables direct connection to 5V microcontrollers or sensors without level-shifter circuitry |
| AEC-Q100 Grade 1 Qualification | Validated for automotive applications requiring -40°C to +125°C operation and PPAP compliance |
| Low Dynamic Power Consumption | Typical CPD = 16pF at 10MHz - reduces switching losses in battery-powered or thermally constrained modules |
| ESD Robustness | 2000V HBM / 1000V CDM - exceeds AEC-Q100-002/-011, improving board-level reliability in manufacturing and field use |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Same logic function and IOFF, but rated only to +85°C (commercial grade), not AEC-Q100 qualified | Lacks automotive qualification and extended temperature support - unsuitable for under-hood or chassis-mounted use | Select only for cost-sensitive non-automotive industrial or consumer designs where Grade 1 temp range is unnecessary |
| 74LVC1G32GW,125 | Identical AEC-Q100 Grade 1 spec, but in SOT353 (2.15mm × 2.1mm) package with 0.65mm pitch | Smaller footprint but higher thermal resistance (θJA = 385°C/W vs. 184°C/W) - limits high-duty-cycle operation in compact layouts | Prefer for space-constrained PCBs where thermal load is low; choose W5 for better thermal performance in dense automotive modules |
Compared with SN74LVC1G32DBVR and 74LVC1G32GW,125, the 74LVC1G32QW5-7 uniquely balances AEC-Q100 qualification, superior thermal dissipation in SOT25, and proven 5.5V input tolerance - making it optimal for automotive power sequencing and industrial safety interlocks requiring long-term reliability.

FAQ
What is the maximum input voltage the 74LVC1G32QW5-7 can tolerate?
The device accepts input voltages up to 5.5V regardless of VCC level, enabling direct interface with 5V logic or sensors without level-shifting circuitry. This specification is validated per AEC-Q100 and applies across the full operating temperature range (-40°C to +125°C).
Does the 74LVC1G32QW5-7 support partial power-down operation?
Yes - its IOFF circuitry actively disables the output when VCC is at 0V or near-ground, preventing damaging back-current from live inputs into a powered-down system. This feature is fully characterized and required for AEC-Q100 Grade 1 compliance.
What is the typical propagation delay at 3.3V supply?
At VCC = 3.3V and TA = +25°C, typical propagation delay is 2.1ns, with guaranteed maximum of 6.0ns across -40°C to +125°C. This value applies to both tPLH and tPHL transitions and is measured under standard load conditions (CL = 50pF, RL = 500Ω).
Is the 74LVC1G32QW5-7 RoHS and halogen-free compliant?
Yes - it is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes Incorporated definition: <900ppm Br, <900ppm Cl, <1000ppm Sb). Compliance documentation is available on the manufacturer's quality portal.
