Product details
Overview
74LVC1G08SE-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT353 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.3V. It supports partial power-down via IOFF circuitry and enables voltage-level shifting in mixed-voltage digital interfaces such as USB peripheral control logic or I²C signal conditioning.
For engineers reviewing the 74LVC1G08SE-7 datasheet, 74LVC1G08SE-7 pinout, 74LVC1G08SE-7 application, or 74LVC1G08SE-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), IOFF-enabled isolation during power sequencing, 3.3V-compatible output drive strength, and SOT353 footprint compatibility with space-constrained portable electronics designs.
Technical Context
This device implements standard Boolean AND logic (Y = A • B) using CMOS technology with push-pull outputs. Its IOFF feature actively disables output terminals when VCC = 0V, preventing back-current flow in partially powered systems - critical for hot-swap and multi-rail power domain isolation.
Input tolerance up to 5.5V allows direct interfacing with higher-voltage logic families while powered from lower supplies (e.g., 1.8V or 2.5V), and its propagation delay ranges from 0.5ns (typ) at 5.0V to 2.1ns (typ) at 3.3V, supporting timing-critical signal gating in microcontroller peripheral enable paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables operation across 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - Allows safe connection of 5V signals to inputs even when VCC is as low as 1.65V. |
| Output Drive Strength | ±24mA at VCC = 3.3V - Sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads (<30pF). |
| Propagation Delay | 0.5ns (min) to 4.5ns (max) at 3.3V - Supports >100MHz toggle rates in non-critical timing paths. |
| IOFF Leakage Current | ±200μA max at -40°C to +125°C - Ensures robust signal isolation during system power-down sequences. |
| ESD Protection | 2000V HBM, 1000V CDM - Meets industrial-grade ESD robustness requirements without external protection. |
| Operating Temperature | -40°C to +125°C - Qualified for automotive under-hood and industrial control environments. |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm lead pitch) - ultra-compact 5-pin SC-70 package optimized for high-density PCB layouts in portable and battery-powered devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First logic input; accepts 0V–5.5V regardless of VCC level; internally clamped. |
| 2 (B) | Data Input | Second logic input; identical electrical behavior to Pin 1; supports wired-OR expansion. |
| 3 (GND) | Ground Reference | Primary return path for all internal current; must be connected before VCC for reliable startup. |
| 4 (Y) | Data Output | Push-pull AND result output; drives high/low actively; sinks or sources up to 24mA at 3.3V. |
| 5 (VCC) | Supply Voltage | Power rail input; powers internal logic and output stage; IOFF activates when VCC = 0V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range (1.65–5.5V) | Eliminates need for separate voltage translators when interfacing 1.8V FPGAs with 3.3V peripherals. |
| IOFF Partial Power-Down Support | Prevents backfeeding into powered-down sections - essential for PCIe slot power management and USB OTG host negotiation. |
| 5.5V-Tolerant Inputs | Enables direct connection to legacy 5V GPIOs or microcontroller reset lines without external resistors or diodes. |
| Low Dynamic Power Consumption | Typical ICC = 0.1μA at 3.3V - reduces quiescent current in always-on sensor interface circuits. |
| Small SOT353 Footprint | 2.0mm × 2.0mm area saves >40% board space vs. SOIC-8 AND gates - critical for wearable and hearing aid PCBs. |
Applications

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 | Texas Instruments SOT23-5 variant; identical logic function and voltage specs but slightly higher typical tPD (2.5ns vs. 2.1ns at 3.3V). | Same SOT footprint but different pad layout (0.95mm pitch vs. 0.65mm); requires PCB redesign. | Select when TI ecosystem alignment or existing SOT23-5 land pattern is preferred. |
| 74AUP1G08GW,125 | Nexperia XSON-6 package; lower static current (0.05μA typ) and improved 1.2V–3.6V range, but no 5.5V input tolerance. | Not suitable for mixed 5V/3.3V interfaces; limited to sub-3.6V systems like Bluetooth LE modules. | Choose for ultra-low-power battery applications where 5V tolerance is unnecessary. |
Compared with SN74LVC1G08DBVR, the 74LVC1G08SE-7 offers tighter propagation delay and smaller SOT353 footprint; versus 74AUP1G08GW, it provides broader voltage interoperability at the cost of marginally higher ICC - making it optimal for mixed-supply embedded control points.

FAQ
Can 74LVC1G08SE-7 operate reliably at 1.65V supply?
Yes. The device is fully characterized down to 1.65V: propagation delay remains within 8.0ns (max), output drive meets ±4mA (min), and input thresholds scale correctly (VIH = 0.65×VCC). This enables use in 1.8V systems with margin, including battery-powered IoT sensors operating near end-of-life voltage.
Does the SOT353 package support reflow soldering per JEDEC J-STD-020?
Yes. The SOT353 package is rated for standard lead-free reflow profiles (peak 260°C, 20–40 sec above 217°C). Thermal resistance θJA = 371°C/W confirms suitability for moderate-power-density layouts; recommended pad layout matches Diodes' published footprint (C1 = 1.90mm, G = 1.30mm).
What happens to the output when VCC = 0V and inputs are pulled high?
When VCC = 0V, the IOFF circuit disables the output stage, placing Y in high-impedance state with leakage ≤±200μA. Inputs remain 5.5V-tolerant, so externally driven A/B signals will not backfeed - enabling safe hot-insertion into live backplanes or modular systems.
Is 74LVC1G08SE-7 pin-compatible with other 74LVC1G08 variants in different packages?
No. While logic function and pin functions (A, B, Y, VCC, GND) are identical, physical pinouts differ: SOT353 uses 1-A, 2-B, 3-GND, 4-Y, 5-VCC; SOT25 uses 1-A, 2-B, 3-GND, 4-Y, 5-VCC - same order but incompatible pitch (0.65mm vs. 0.95mm). DFN variants have entirely different terminal arrangements.
