Product details
Overview
74LVC32AS14-13 from Diodes Incorporated is a quadruple 2-input OR gate logic IC operating from 1.65V to 3.6V, with 5.5V-tolerant inputs, IOFF partial-power-down protection, ±24mA output drive at 3.3V, and SO-14 package-used for voltage-level shifting and signal isolation in mixed-voltage digital systems.
For engineers reviewing the 74LVC32AS14-13 datasheet, 74LVC32AS14-13 pinout, 74LVC32AS14-13 application, or 74LVC32AS14-13 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF leakage (<20 µA), propagation delay (2.5–10.2 ns), output drive capability (±24mA), and dual-package availability (SO-14/TSSOP-14).
Technical Context
This device implements four independent positive-logic OR functions (Y = A + B) in a single monolithic CMOS structure. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and partial-power-down system architectures.
Input voltage tolerance up to 5.5V allows direct interfacing with legacy 5V logic while powered from 1.8V or 3.3V rails. The device supports voltage translation across supply domains without external level shifters, verified across –40°C to +125°C operating temperature range.
Key Specifications

|---|---|
| Supply Voltage Range | 1.65V to 3.6V - enables compatibility with 1.8V, 2.5V, and 3.3V logic families |
| Input Voltage Tolerance | Up to 5.5V - permits direct connection to 5V signals without clamping diodes or external translators |
| IOFF Leakage Current | <20 µA at VCC = 0V - ensures robust isolation during partial power-down states |
| Output Drive Strength | ±24mA at VCC = 3.3V - supports driving moderate capacitive loads and fan-out to multiple CMOS inputs |
| Propagation Delay | 2.5 ns (typ) at 3.3V - delivers high-speed performance suitable for 100+ MHz clock-domain boundary logic |
| ESD Protection | 2000V HBM, 200V MM - exceeds JEDEC standards for board-level handling and system-level robustness |
| Operating Temperature | –40°C to +125°C - qualified for industrial and extended-temperature embedded applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32APWRE4 (TI) | Same logic function, 1.65–3.6V supply, 5.5V-tolerant inputs, but TSSOP-14 only; IOFF leakage spec not published | Lacks explicit IOFF characterization - less suitable for partial-power-down safety-critical use cases | Select if TSSOP footprint preferred and IOFF verification not required |
| 74LVC32AD,118 (Nexperia) | Identical SO-14 package and pinout; same VCC range and 5.5V input tolerance; IOFF leakage ≤10 µA (tighter spec) | Higher ESD rating (4kV HBM), lower typical propagation delay (2.2 ns @ 3.3V) | Preferred for high-reliability industrial designs requiring tighter parametric control and enhanced ESD robustness |

FAQ
Can 74LVC32AS14-13 operate with a 5V supply?
No. The absolute maximum VCC rating is 6.5V, but the recommended operating range is strictly 1.65V to 3.6V. Applying 5V to VCC exceeds specification and risks permanent damage. However, inputs tolerate up to 5.5V regardless of VCC level-enabling safe 5V signal reception on a 3.3V-powered device.
What is the purpose of the IOFF feature?
The IOFF circuit disables all outputs when VCC = 0V, preventing current from flowing backward through I/O pins into a powered-down supply rail. This protects downstream circuitry during hot-plug, partial-power-down, or multi-rail sequencing scenarios-critical for system reliability in servers, telecom modules, and modular instrumentation.
Does this part support 1.8V logic interfaces?
Yes. With a minimum VCC of 1.65V and guaranteed VIH/VIL thresholds down to 1.65V (e.g., VIH ≥ 0.65×VCC), the 74LVC32AS14-13 fully supports 1.8V CMOS logic families. It delivers 1.2V VOH and 0.45V VOL at 1.65V supply, meeting standard 1.8V interface voltage margins.
Is there a pin-compatible TSSOP version?
Yes-the 74LVC32AT14-13 is the TSSOP-14 variant, sharing identical logic function, pinout, electrical specifications, and thermal characteristics (θJA = 159°C/W). It differs only in package dimensions (4.5mm × 5.1mm vs. SO-14's 8.7mm × 4.0mm) and tape-and-reel carrier (same -13 suffix).
