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 flexible logic reconfiguration in space-constrained portable power management and interface signal conditioning circuits.
For engineers reviewing the SN74LVC1G3208 datasheet, SN74LVC1G3208 pinout, SN74LVC1G3208 application, or SN74LVC1G3208 equivalent, key selection criteria include its dual-voltage input tolerance (up to 5.5 V), nanoscale SOT-23 (DBV) package, Ioff-enabled partial-power-down capability, and configurable 2-input OR/AND mode via pin strapping.
Technical Context
The SN74LVC1G3208 implements a fixed positive-logic OR-AND function with three inputs (A, B, C) and one output (Y), where output state depends on simultaneous evaluation of A+B followed by AND with C. Its Ioff circuitry actively disables outputs during power-down to prevent back-drive current, supporting hot-plug and mixed-voltage system interconnects.
Input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow-rising signals, while voltage translation capability allows interfacing 5-V inputs with lower VCC rails. The device operates across –40°C to 125°C and meets JESD 78 Class II latch-up and JESD 22 ESD standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct connection to common supply rails including 1.8 V, 2.5 V, 3.3 V, and 5 V systems |
| Max tpd | 5 ns at 3.3 V - enables use in high-speed digital control paths with sub-10 ns timing budgets |
| Output Drive | ±24 mA at 3.3 V - sufficient to directly drive multiple LVC inputs or small capacitive loads without buffering |
| Ioff Current | ±10 µA max - ensures safe isolation during partial power-down, preventing current backflow into powered sections |
| Input Voltage Range | –0.5 V to 5.5 V - accepts overvoltage-tolerant inputs up to 5.5 V regardless of VCC level |
| Operating Temp | –40°C to 125°C - qualified for industrial and extended-temperature embedded applications |
Pinout & Package
SOT-23 (DBV) 6-pin package: 1.45 mm max height, 2.9 mm × 1.6 mm body, gull-wing leads, JEDEC MO-178 compliant, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | First OR input; tied to GND to configure as 2-input AND gate (Y = B ● C) |
| 2 (B) | Input | Second OR input; tied to GND to configure as 2-input AND gate (Y = A ● C) |
| 3 (GND) | Ground Reference | Power return path; required for stable logic threshold and Ioff functionality |
| 4 (C) | Input | AND-enable input; tied to VCC to configure as 2-input OR gate (Y = A + B) |
| 5 (Y) | Output | Active-high logic output; drives CMOS loads with rail-to-rail swing and 24-mA sink/source |
| 6 (VCC) | Supply | Core power rail; powers internal logic and enables Ioff control during power sequencing |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Function | Supports three modes - OR-AND (Y = (A+B)●C), OR (Y = A+B when C=VCC), AND (Y = B●C when A=GND) - reducing BOM count in multi-function designs |
| Ioff Partial-Power-Down | Disables outputs when VCC = 0 V, eliminating back-drive risk during hot-swap or power-gating sequences |
| Input Hysteresis | 250 mV typical at 3.3 V - suppresses chatter on noisy or slowly transitioning control lines without external Schmitt triggers |
| Voltage Translation | Accepts 5.5-V inputs while operating at VCC as low as 1.65 V - simplifies level-shifting between legacy and low-voltage subsystems |
| NanoStar™ Packaging | Dies-as-packages reduce footprint and thermal resistance - DBV variant measures only 2.9 mm × 1.6 mm with 1.45 mm height |
Applications
| Industrial Sensor Interface | Portable Power Sequencing |
|---|---|
Use Scenario: Combining fault signals from multiple sensors (e.g., temperature, pressure, current) before triggering MCU interrupt or shutdown logic. IC Role / Device Role / Timing Role: Performs wired-OR aggregation with enable gating - only asserts output when any sensor fault occurs AND system is active (C = VCC). Use Value: Eliminates need for discrete diodes or additional logic gates; leverages Ioff to isolate during sleep mode without leakage. | Use Scenario: Enabling downstream DC-DC converters only after primary rail reaches regulation and microcontroller grants permission. IC Role / Device Role / Timing Role: Acts as an AND gate (A = primary rail OK, C = MCU enable, B unused or tied) to enforce sequential power-up dependencies. Use Value: Uses single gate instead of dedicated power sequencer IC; benefits from 5.5-V tolerant inputs monitoring 5-V rails while running at 3.3 V. |
| USB-C Port Controller Support | Low-Power IoT Edge Node |
Use Scenario: Validating CC line detection status and VBUS presence before enabling USB data path or charging circuitry. IC Role / Device Role / Timing Role: Configured as OR-AND gate: OR of two CC pin states (A/B) ANDed with VBUS_OK (C) to confirm valid attachment. Use Value: Provides deterministic logic response within 5 ns; hysteresis prevents false toggling due to CC line noise during plug insertion. | Use Scenario: Controlling wake-up signal routing between motion sensor, BLE radio, and application MCU based on activity state and battery voltage threshold. IC Role / Device Role / Timing Role: Functions as OR gate (A = motion detect, B = BLE event, C = VBAT_OK) to assert wake-up only when power is sufficient. Use Value: Operates down to 1.65 V, matching Li-ion discharge curve; consumes <10 µA ICC, preserving battery life during deep sleep. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVT | Dedicated 2-input AND gate; no OR-AND configurability or Ioff support | Lacks input overvoltage tolerance and partial-power-down protection | Select when only fixed AND function is needed and system lacks hot-swap requirements |
| SN74LVC1G32DBVT | Dedicated 2-input OR gate; no AND-enable input or configurable mode | No voltage translation capability beyond VCC range; no Ioff | Choose for simple OR logic where C-input gating and 5.5-V input tolerance are unnecessary |
Compared with SN74LVC1G08DBVT and SN74LVC1G32DBVT, the SN74LVC1G3208 offers unique functional flexibility through pin-strappable OR-AND/AND/OR modes, critical Ioff protection for dynamic power domains, and 5.5-V input tolerance - making it superior for adaptive interface logic in mixed-voltage, power-aware systems.

FAQ
What logic function does the SN74LVC1G3208 implement by default?
The SN74LVC1G3208 implements the positive-logic OR-AND function Y = (A + B) ● C. Inputs A and B feed an OR stage whose output is ANDed with input C to produce Y. This base configuration is fixed in silicon and cannot be altered via control pins, though external strapping enables alternate 2-input OR or AND behavior.
Can the SN74LVC1G3208 operate with a 1.8-V supply and accept 3.3-V inputs?
Yes. The SN74LVC1G3208 supports VCC from 1.65 V to 5.5 V and accepts input voltages up to 5.5 V independent of VCC level. At 1.8 V VCC, it reliably interprets 3.3-V inputs as logic HIGH per its VIH specification (0.65 × VCC min), enabling seamless level translation without external components.
How does the Ioff feature of the SN74LVC1G3208 protect system-level interconnects?
The Ioff feature disables all outputs when VCC = 0 V, limiting off-state leakage to ±10 µA max. This prevents damaging back-current flow from live signal lines into a powered-down section - essential for hot-plug connectors, modular subsystems, and partial-power-down architectures. The SN74LVC1G3208 maintains this protection across –40°C to 125°C.
What is the maximum propagation delay of the SN74LVC1G3208 under typical conditions?
The maximum propagation delay (tpd) of the SN74LVC1G3208 is 5 ns at VCC = 3.3 V, CL = 15 pF, and TA = 25°C. Delay increases with load capacitance and decreases with higher VCC - e.g., 3.4 ns at 5 V and 14 ns at 1.8 V under same conditions. All values are guaranteed over –40°C to 125°C per datasheet limits.
Which package variants are available for the SN74LVC1G3208, and what is the footprint size of the DBV option?
The SN74LVC1G3208 is offered in SOT-23 (DBV), SC70 (DCK), and DSBGA (YZP) packages. The DBV variant measures 2.9 mm × 1.6 mm with 1.45 mm max height and 0.95 mm lead pitch. Its land pattern requires 0.6 mm × 0.95 mm pads, 0.7 mm solder mask openings, and 1.1 mm stencil apertures per IPC-7351 guidelines.
