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. It supports 5-V VCC, delivers ±24-mA output drive at 3.3 V, exhibits 5 ns max propagation delay at 3.3 V, and features Ioff for live insertion-used in logic-level translation and configurable gate applications within portable power management systems.
For engineers reviewing the SN74LVC1G3208 datasheet, SN74LVC1G3208 pinout, SN74LVC1G3208 application, or SN74LVC1G3208 equivalent, key selection factors include its dual-mode configurability (OR/AND via input tie-offs), 250-mV input hysteresis for noise immunity, Ioff-enabled partial-power-down capability, and NanoFree™/NanoStar™ packaging for ultra-compact PCB layouts.
Technical Context
The SN74LVC1G3208 implements a fixed Boolean function Y = (A + B) ● C using CMOS logic with Schmitt-trigger input hysteresis (250 mV typ at 3.3 V). Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current and enabling hot-swap compatibility.
All inputs tolerate up to 5.5 V regardless of VCC level, enabling voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. The device operates across –40°C to 125°C and meets JESD 78 Class II latch-up performance (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables interoperability across legacy and low-voltage logic families without level shifters. |
| Max tpd | 5 ns at 3.3 V - Supports high-speed timing-critical paths in portable MCU peripherals and sensor interface logic. |
| Output Drive | ±24 mA at 3.3 V - Sufficient to directly drive multiple LVC inputs or small capacitive loads (<15 pF) without buffering. |
| Ioff Current | ±10 µA max - Ensures safe isolation during partial-power-down, critical for hot-pluggable modules and battery-backed subsystems. |
| Input Hysteresis | 250 mV typ at 3.3 V - Rejects slow-rising or noisy signals (e.g., mechanical switch inputs, long traces), eliminating external RC filtering. |
| Operating Temp | –40°C to 125°C - Qualified for under-hood automotive, industrial control, and extended-temperature embedded applications. |
Pinout & Package
SN74LVC1G3208 is available in three ultra-small packages: SOT-23 (DBV), SC70 (DCK), and DSBGA (YZP), all 6-pin. The YZTR suffix corresponds to the YZP (DSBGA) package with 0.5-mm pitch, 1.418 mm × 1.358 mm body, and 0.5-mm max height-optimized for space-constrained wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | First OR operand; tied to GND to configure as 2-input AND gate (Y = B ● C). |
| 2 (B) | Input B | Second OR operand; tied to GND to configure as 2-input AND gate (Y = A ● C). |
| 3 (C) | Input C | AND-enable input; tied to VCC to configure as 2-input OR gate (Y = A + B). |
| 4 (GND) | Ground | Reference return path for logic and I/O; must be low-impedance for noise immunity and Ioff functionality. |
| 5 (Y) | Output | Active-high combinational output; drives full rail-to-rail swing (VOH ≥ VCC – 0.1 V, VOL ≤ 0.55 V at 3.3 V). |
| 6 (VCC) | Supply | Single supply input; powers internal logic and output stage; accepts 1.65–5.5 V with no external regulation required. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Function | Supports OR-AND (Y = (A + B) ● C), 2-input OR (C = VCC), or 2-input AND (A or B = GND) - reduces BOM count in multi-function designs. |
| Ioff Partial-Power-Down | Disables outputs when VCC = 0 V, blocking back-current flow - enables safe insertion into live backplanes or hot-swap power rails. |
| Voltage Translation | Inputs accept 0–5.5 V independent of VCC - allows interfacing 5-V sensors or switches with 1.8-V microcontrollers without discrete translators. |
| NanoFree™ Packaging | YZP DSBGA uses die-as-package construction - eliminates bond wires and leadframe, reducing parasitic inductance and footprint by >50% vs. SOT-23. |
| High Noise Immunity | 250-mV input hysteresis - suppresses false triggering on slow edges or EMI-coupled signals in motor control or industrial environments. |
Applications
| Portable Power Sequencing | Industrial Sensor Interface |
|---|---|
Use Scenario: Enabling DC-DC converter rails only after system reset and temperature validation signals are asserted. IC Role / Device Role / Timing Role: Configured as AND gate (A = reset, C = temp_ok) to gate enable signal to PMIC. Use Value: Eliminates need for discrete AND gate + pull-up resistors; Ioff prevents leakage during deep sleep mode. |
Use Scenario: Combining fault flags from multiple analog front-end ICs before triggering MCU interrupt. IC Role / Device Role / Timing Role: OR-AND gate (A = ADC_err, B = DAC_err, C = valid_clock) ensures interrupt only when clock is present. Use Value: Reduces interrupt latency vs. software polling; hysteresis rejects transient noise on fault lines. |
| Automotive Body Control | Wearable Device Status Logic |
Use Scenario: Activating interior lighting only when door open AND ignition off AND ambient light below threshold. IC Role / Device Role / Timing Role: OR-AND gate (A = door_sw, B = ign_off, C = light_low) performs real-time combinatorial decision. Use Value: Meets AEC-Q100 requirements via SN74LVC1G3208-Q1 variant; 125°C rating supports under-dash mounting. |
Use Scenario: Controlling LED blink pattern based on battery charge state AND motion detection status. IC Role / Device Role / Timing Role: Configured as OR gate (C = VCC) to merge low-battery alert and activity pulse signals. Use Value: NanoFree YZP package fits <1.5 mm² area; 10-µA ICC minimizes quiescent drain in always-on wearable modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08YZPR | Dedicated 2-input AND gate; no OR-AND reconfigurability; identical VCC range, drive strength, and YZP package. | Lacks input tie-off flexibility; requires separate OR gate if OR-AND logic needed. | Select when only AND function is required and board layout already accommodates YZP footprint. |
| SN74LVC1G32YZPR | Dedicated 2-input OR gate; no AND-enable input; same electrical specs and YZP package. | Cannot implement AND logic or conditional gating; no hysteresis on inputs. | Choose for pure OR functions where input noise immunity is less critical than cost reduction. |
Compared with SN74LVC1G3208, SN74LVC1G08YZPR offers simpler AND-only behavior but forfeits reconfigurability, while SN74LVC1G32YZPR provides faster OR-only response yet lacks the conditional enable (C-input) essential for safety interlocks and multi-signal arbitration.

FAQ
What logic functions does the SN74LVC1G3208 support?
The SN74LVC1G3208 natively implements Y = (A + B) ● C. By tying input C to VCC, it functions as a 2-input OR gate (Y = A + B); by tying A or B to GND, it acts as a 2-input AND gate (Y = B ● C or Y = A ● C). All configurations retain the same Ioff, hysteresis, and voltage translation capabilities inherent to the SN74LVC1G3208.
Can the SN74LVC1G3208 operate with mixed-voltage inputs?
Yes. Inputs A, B, and C accept voltages from 0 V to 5.5 V regardless of VCC level (1.65 V to 5.5 V), enabling direct interfacing of 5-V switches or sensors with 1.8-V or 2.5-V controllers. This voltage translation capability is intrinsic to the SN74LVC1G3208's input structure and requires no external components.
What is the significance of Ioff in the SN74LVC1G3208?
Ioff disables the output buffers when VCC = 0 V, preventing damaging current from flowing back into the device through powered inputs. This feature makes the SN74LVC1G3208 suitable for live insertion, partial-power-down systems, and back-drive protection-critical in modular systems where boards may be hot-swapped while other sections remain active.
Which package options are available for the SN74LVC1G3208?
The SN74LVC1G3208 is offered in SOT-23 (DBV), SC70 (DCK), and DSBGA (YZP) packages. The YZTR suffix specifically denotes the YZP package: a 0.5-mm-pitch, 1.418 mm × 1.358 mm, 0.5-mm-max-height NanoFree™ die-size ball grid array ideal for ultra-thin wearables and space-limited IoT nodes.
Does the SN74LVC1G3208 meet automotive qualification standards?
The base SN74LVC1G3208 is not automotive-qualified, but TI offers the pin-compatible SN74LVC1G3208-Q1 variant qualified to AEC-Q100 Grade 1 (–40°C to 125°C) with enhanced reliability testing. For automotive body control or infotainment interfaces requiring zero-defect reliability, the Q1 version-not the standard SN74LVC1G3208-is specified.
