Product details
Overview
SN74LVC1G3208 from Texas Instruments is a single 3-input positive OR-AND gate performing Y = (A + B) ● C in 1.65-V to 5.5-V operation, with 5 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for live insertion. It enables configurable logic in space-constrained portable and battery-powered systems.
For engineers reviewing the SN74LVC1G3208 datasheet, SN74LVC1G3208 pinout, SN74LVC1G3208 application, or SN74LVC1G3208 equivalent, key selection criteria include its dual-function capability (OR-AND / OR / AND), 3.3-V/5-V compatibility, nano-packaged footprint, and Ioff-enabled partial-power-down robustness.
Technical Context
The SN74LVC1G3208 implements a fixed Boolean function Y = (A + B) ● C using CMOS logic with input hysteresis (250 mV typ at 3.3 V) for noise immunity. Its inputs accept voltages up to 5.5 V independent of VCC, enabling level translation.
It supports three functional configurations via external pin tying: full 3-input OR-AND (all inputs active), 2-input OR (C tied to VCC), or 2-input AND (A or B tied to GND). The Ioff circuit disables outputs during power-down to prevent back-drive current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without external level shifters. |
| Max tpd | 5 ns at 3.3 V - Ensures timing-critical signal routing in high-speed digital control paths with minimal latency. |
| Output Drive | ±24 mA at 3.3 V - Sufficient to directly drive multiple LVC inputs or small capacitive loads without buffering. |
| Ioff | ±10 µA max - Prevents damaging back-current flow when VCC is unpowered, supporting hot-swap and partial-power-down systems. |
| Input Hysteresis | 250 mV typ at 3.3 V - Rejects slow-rising or noisy input edges, improving reliability in industrial or automotive sensor interface circuits. |
| ESD Rating | 2000-V HBM - Meets standard robustness requirements for handling and board-level integration without special ESD precautions. |
Pinout & Package
SN74LVC1G3208 is packaged in the SC70-6 (DCK) package: 2.0 mm × 1.25 mm × 0.9 mm body, 0.65 mm pitch, lead-free (NIPDAU/SN), MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | First OR operand in Y = (A + B) ● C; can be tied to GND to configure as 2-input AND (Y = B ● C). |
| 2 (B) | Input B | Second OR operand; can be tied to GND to configure as 2-input AND (Y = A ● C). |
| 3 (GND) | Ground | Reference return path for all internal logic and output stages; must be low-impedance for stable switching. |
| 4 (C) | Input C | AND operand; tying to VCC configures device as 2-input OR gate (Y = A + B). |
| 5 (Y) | Output | Active-high, non-inverting output delivering the result of (A + B) ● C; drives loads up to ±24 mA. |
| 6 (VCC) | Supply | Power rail for logic core and output buffers; supports 1.65–5.5 V; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Function | Single device delivers OR-AND, OR, or AND behavior via external pin ties-reducing BOM count and PCB footprint. |
| Voltage Translation | Inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), enabling seamless interfacing between mixed-voltage subsystems. |
| Ioff Protection | Outputs enter high-impedance state with leakage < ±10 µA when VCC = 0 V-enabling safe live insertion into powered backplanes. |
| NanoFree™ Packaging | DCK (SC70-6) package uses die-as-package construction for ultra-small area (2.5 mm²) and low thermal resistance (259 °C/W). |
| Low Static Power | Max ICC = 10 µA across full VCC range-critical for always-on battery-backed logic and IoT endpoint nodes. |
Applications
| Portable Power Management | Industrial Sensor Interface |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DCKR | Fixed 2-input AND gate; no OR-AND or configurability; identical DCK package and VCC range. | Lacks multi-function flexibility; suitable only when AND-only behavior is required. | Select when design needs dedicated AND logic without reconfiguration overhead or pin tie complexity. |
| SN74LVC1G32DCKR | Fixed 2-input OR gate; no AND capability; same package, drive strength, and Ioff support. | Cannot implement AND or OR-AND functions; limited to OR-only use cases. | Choose when OR functionality suffices and eliminates need for unused input management or external pull-ups/downs. |

FAQ
What logic functions does the SN74LVC1G3208 support?
The SN74LVC1G3208 natively performs Y = (A + B) ● C. By tying input C to VCC, it operates as a 2-input OR gate (Y = A + B); by tying A or B to GND, it functions as a 2-input AND gate (Y = B ● C or Y = A ● C). All configurations retain the same SN74LVC1G3208 pinout and electrical specs.
Can SN74LVC1G3208 interface between 3.3-V and 5-V systems?
Yes. SN74LVC1G3208 inputs accept voltages up to 5.5 V regardless of VCC, allowing 5-V signals to safely drive its inputs when VCC = 3.3 V. Its outputs swing rail-to-rail (0 V to VCC), so SN74LVC1G3208 output levels match the 3.3-V domain unless buffered.
Does SN74LVC1G3208 support partial power-down?
Yes. SN74LVC1G3208 features Ioff circuitry that disables outputs and limits leakage to ±10 µA when VCC = 0 V, preventing back-current flow from live inputs or outputs. This makes SN74LVC1G3208 suitable for hot-swap and modular power architectures.
What is the maximum operating temperature for SN74LVC1G3208?
The SN74LVC1G3208 is rated for operation from –40°C to +125°C ambient temperature. This extended range is validated per JEDEC JESD78 latch-up testing (>100 mA) and supported across all package variants including DCK, DBV, and YZP.
Is there an automotive-grade version of SN74LVC1G3208?
Yes. The SN74LVC1G3208-Q1 is the AEC-Q100 qualified automotive variant, tested for high-reliability operation in vehicle environments. It shares identical logic functionality, pinout, and package options with the commercial SN74LVC1G3208 but adds enhanced screening and traceability.
