Product details
Overview
SN74LVC1G08DBVTG4 from Texas Instruments is a single 2-input positive-AND gate in SOT-23-5 (DBV) package, performing Y = A • B logic with 3.6ns max propagation delay at 3.3V, ±24mA output drive, and 5.5V-tolerant inputs - used for power sequencing control and signal gating in compact embedded systems.
For engineers reviewing the SN74LVC1G08DBVTG4 datasheet, SN74LVC1G08DBVTG4 pinout, SN74LVC1G08DBVTG4 application, or SN74LVC1G08DBVTG4 equivalent, key selection criteria include input overvoltage tolerance (up to 5.5V), Ioff-enabled live insertion support, ultra-low ICC (≤10μA), 1.65V–5.5V supply range, and verified operation across –40°C to 125°C industrial temperature range.
Technical Context
This device implements standard CMOS positive-logic AND functionality with balanced push-pull outputs capable of sourcing and sinking equal current (±24mA at 3.3V). Its Ioff circuitry disables all outputs when VCC = 0V, enabling safe hot-plug operation and back-drive protection.
The SN74LVC1G08DBVTG4 features overvoltage-tolerant inputs (VI up to 5.5V independent of VCC), supports voltage-level translation down to VCC, and maintains guaranteed switching performance across 1.65V–5.5V supply voltages - including 3.6ns tpd at 3.3V/CL=15pF and 4.5ns tpd at 3.3V/CL=30pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive-AND (Y = A • B); enables basic digital enable/control gating |
| Propagation Delay (tpd) | 3.6ns max at 3.3V, CL = 15pF - ensures timing-critical signal path compatibility in high-speed logic interfaces |
| Supply Voltage Range | 1.65V to 5.5V - supports mixed-voltage system integration and battery-backed operation |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC - allows interfacing with higher-voltage controllers without level shifters |
| Output Drive Strength | ±24mA at 3.3V - sufficient to directly drive multiple 74LVC inputs or small capacitive loads (≤50pF) |
| Quiescent Current (ICC) | 10μA max - enables always-on monitoring circuits with negligible standby power impact |
| Ioff Support | Active at VCC = 0V - prevents back-driving and enables live insertion in modular systems |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 2.8mm body, 2.9mm × 1.6mm footprint, 1.45mm height, gull-wing leads, RoHS-compliant, moisture sensitivity level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Primary logic input; accepts 0–5.5V; must be terminated to VCC or GND if unused |
| 2 | B | Secondary logic input; identical electrical behavior to Pin 1; forms AND operand pair with A |
| 3 | GND | Ground reference for all internal circuitry and output sink paths; requires low-impedance PCB connection |
| 4 | Y | CMOS push-pull output; drives HIGH to VCC–0.1V (min) and LOW to ≤0.1V (max) under load |
| 5 | VCC | Positive supply input; requires local 0.1μF bypass capacitor; supports 1.65–5.5V operation |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Accepts up to 5.5V regardless of VCC - eliminates need for external level translators in mixed-supply systems |
| Ioff partial-power-down mode | Disables outputs and limits leakage to ±10μA when VCC = 0V - enables safe hot-swap in modular backplanes |
| Ultra-fast switching | 3.6ns max tpd at 3.3V/15pF - meets timing budgets for 100+ MHz control logic and clock-enable paths |
| Low static power | 10μA max ICC across full temperature range - suitable for battery-powered sensor nodes and always-on monitors |
| Robust ESD protection | 2000V HBM per JESD22-A114 - exceeds industrial handling requirements without additional protection circuitry |
Applications
| Power Sequencing Control | Signal Enable Gating |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Same silicon, tape-and-reel packaging (3000 pcs/reel vs. 250 pcs for DBVTG4); identical electrical specs and pinout | No functional difference; optimized for high-volume automated assembly rather than prototyping or low-quantity orders | Select DBVR for production runs requiring full reel delivery and SMT placement efficiency |
| 74LVC1G08GW,125 | NXP variant in SC-70-5 (SOT353) package; 3.5ns tpd at 3.3V but rated only to 125°C (vs. TI's 125°C max); 5.5V input tolerance confirmed | Smaller footprint (2.0mm × 1.25mm) but lower thermal resistance margin; same industrial temp range and logic function | Choose GW,125 only when board area is constrained below SOT-23 limits and thermal derating is verified |
Compared with SN74LVC1G08DBVTG4, the DBVR offers identical performance with volume-optimized packaging, while the NXP 74LVC1G08GW,125 trades slightly better speed for smaller size and tighter thermal margins - making SN74LVC1G08DBVTG4 optimal for general-purpose industrial designs prioritizing supply chain consistency and thermal robustness.

FAQ
What is the maximum operating temperature for SN74LVC1G08DBVTG4?
The SN74LVC1G08DBVTG4 is rated for continuous operation from –40°C to +125°C ambient temperature. This specification is validated per JEDEC JESD78 Class II latch-up testing and thermal characterization across the full SOT-23-5 package variant, ensuring reliability in industrial and automotive under-hood environments where the SN74LVC1G08DBVTG4 is commonly deployed.
Does SN74LVC1G08DBVTG4 support 5V logic inputs while powered from 3.3V?
Yes, the SN74LVC1G08DBVTG4 supports input voltages up to 5.5V independent of VCC, enabling direct interfacing with 5V microcontrollers or sensors even when VCC is set to 3.3V, 2.5V, or 1.8V. This overvoltage tolerance is implemented via internal protection circuitry - no external level shifters are required when using SN74LVC1G08DBVTG4 in mixed-voltage signal paths.
Can SN74LVC1G08DBVTG4 be used for power sequencing in server motherboards?
Yes, the SN74LVC1G08DBVTG4 is explicitly applied in server motherboard and PSU designs for power sequencing verification. Its ability to perform real-time AND logic on multiple power-good signals (e.g., VDD_CPU and VDD_SOC), combined with Ioff support and 125°C operation, makes SN74LVC1G08DBVTG4 suitable for validating rail readiness before releasing processor reset in high-density computing platforms.
What is the recommended bypass capacitor for SN74LVC1G08DBVTG4?
Texas Instruments recommends a 0.1μF ceramic bypass capacitor placed as close as possible to the VCC pin (Pin 5) of the SN74LVC1G08DBVTG4, with a low-inductance ground return path. For enhanced noise suppression across frequency bands, pairing the 0.1μF cap with a 1μF capacitor in parallel is advised - consistent with layout guidance provided in the official SN74LVC1G08DBVTG4 datasheet.
Is SN74LVC1G08DBVTG4 pin-compatible with other SOT-23-5 logic gates?
The SN74LVC1G08DBVTG4 uses the standard SOT-23-5 pinout (A-B-GND-Y-VCC), matching TI's SN74LVC1Gxx series and compatible with industry-standard 2-input logic gates in the same package. However, function-specific pin assignments (e.g., AND vs. OR vs. NAND) differ - always verify logic diagram and truth table before substitution, as SN74LVC1G08DBVTG4 is not functionally interchangeable with non-AND variants despite identical pin mapping.
