Product details
Overview
74LVC1G08W5-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT25 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and IOFF partial-power-down protection. It enables voltage-level shifting and signal gating in mixed-voltage digital interfaces such as USB peripheral control and I²C bus buffering.
For engineers reviewing the 74LVC1G08W5-7 datasheet, 74LVC1G08W5-7 pinout, 74LVC1G08W5-7 application, or 74LVC1G08W5-7 equivalent, this device is selected for low-voltage logic interfacing where input overvoltage tolerance, compact footprint, and power-down isolation are required in space-constrained consumer and computing systems.
Technical Context
The 74LVC1G08W5-7 implements standard positive Boolean AND logic (Y = A · B) using CMOS technology with push-pull outputs. Its IOFF circuit disables output leakage during partial power-down, preventing backflow current when VCC = 0V while inputs remain active at up to 5.5V.
It supports wide-voltage operation (1.65–5.5V), delivers 24mA sink/source at 3.3V, and achieves propagation delays as low as 0.5ns (typ.) at 5.0V. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), enabling reliable TTL-level compatibility across supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive AND gate (Y = A · B); performs basic combinational logic gating in digital control paths. |
| Supply Voltage Range | 1.65V to 5.5V; enables direct interface between 1.8V, 2.5V, 3.3V, and 5V subsystems without level shifters. |
| Input Voltage Tolerance | Up to 5.5V independent of VCC; allows safe connection to higher-voltage signals in mixed-rail designs. |
| Output Drive Strength | ±24mA at VCC = 3.3V; sufficient to drive multiple LVC loads or small capacitive buses (e.g., I²C pull-up networks). |
| IOFF Leakage Current | ±200μA max at TA = –40°C to +125°C; ensures <100μA backfeed during system power sequencing or sleep states. |
| Propagation Delay | 0.5ns (min) to 6.0ns (max) at VCC = 3.3V; supports >100MHz toggle rates in non-critical timing paths. |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM; meets industrial-grade robustness requirements without external protection diodes. |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with exposed pad not connected internally.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Primary logic input; accepts 0–5.5V regardless of VCC; must be tied high/low if unused. |
| 2 | GND | Ground reference for logic and power; connects to PCB ground plane for noise immunity and thermal dissipation. |
| 3 | VCC | Positive supply rail; decoupling capacitor (100nF) required within 5mm for stable switching performance. |
| 4 | Y | Push-pull output; drives high/low actively; compatible with LVTTL, LVCMOS, and 5V-tolerant receivers. |
| 5 | B | Secondary logic input; electrically identical to Pin 1; supports asynchronous gating with A. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range (1.65–5.5V) | Eliminates need for dedicated level translators in multi-rail SoC peripherals and FPGA I/O banks. |
| 5.5V-Tolerant Inputs | Permits direct connection to legacy 5V logic or microcontroller GPIO without series resistors or clamps. |
| IOFF Partial-Power-Down Mode | Prevents destructive current flow from live inputs into unpowered VCC domains during hot-swap or sleep transitions. |
| ±24mA Output Drive at 3.3V | Drives 10+ LVC loads or 30pF bus capacitance at full speed, reducing fanout limitations in dense PCB layouts. |
| Low Dynamic Power (16pF Cpd) | Minimizes switching current in battery-powered devices; ICC < 200μA at 5.5V with static inputs. |
Applications
| USB Peripheral Control | I²C Bus Buffering |
|---|---|
|
Use Scenario: Enabling/disabling USB device enumeration based on host handshake signals. IC Role / Device Role / Timing Role: AND gate combines VBUS presence and reset assertion to gate downstream USB PHY enable. Use Value: Prevents spurious device activation during hot-plug; IOFF blocks backfeed when host powers down while VBUS remains active. |
Use Scenario: Isolating I²C master and slave segments during firmware update to prevent bus contention. IC Role / Device Role / Timing Role: Bidirectional signal gating element controlled by MCU GPIO to segment clock/data lines. Use Value: Maintains 5.5V-tolerant input compatibility with 3.3V I²C masters; 24mA drive sustains rise time across 200pF total bus capacitance. |
| Power Sequencing Logic | Low-Power Sensor Interface |
|
Use Scenario: Generating synchronized enable signals for multiple voltage rails in embedded power management. IC Role / Device Role / Timing Role: Combines "power good" and "system ready" flags to assert final rail enable only when both conditions are met. Use Value: Ensures strict sequencing order; IOFF prevents false triggering during brown-out recovery when one rail powers down before others. |
Use Scenario: Gating sensor data transmission to MCU only when motion detection and battery voltage thresholds are satisfied. IC Role / Device Role / Timing Role: Low-power logic gate combining accelerometer interrupt and ADC voltage comparator outputs. Use Value: Reduces average current draw by disabling RF transmission path until dual conditions are true; 1.65V operation extends battery life in coin-cell 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 part in SOT-23-5 package; identical logic function and 1.65–5.5V range but lower max output drive (±24mA same, but derated above 3.3V). | Lacks explicit IOFF specification; not rated for partial-power-down use with live inputs. | Select when TI ecosystem alignment or alternate sourcing is required; verify IOFF absence does not impact system power sequencing. |
| 74AUP1G08GW,125 | Nexperia part in SC-70-5; ultra-low power (ICC < 1μA typ.), but narrower supply range (0.8–3.6V) and lower drive (±4mA at 3.0V). | Optimized for sub-1V mobile I/O; incompatible with 5V-tolerant or 5V-bus interfacing. | Choose for battery-sensitive wearables where 3.3V-only operation and nanowatt static power dominate design priorities. |
Compared with SN74LVC1G08DBVR, the 74LVC1G08W5-7 provides guaranteed IOFF behavior critical for mixed-rail hot-swap systems; versus 74AUP1G08GW, it trades ultra-low static power for broader voltage support and higher drive-making it suitable for general-purpose industrial and computing interfaces.

FAQ
Can 74LVC1G08W5-7 operate with VCC = 1.5V?
No. The recommended minimum operating voltage is 1.65V per the datasheet's Recommended Operating Conditions table. At 1.5V, the device may retain state but fails to meet guaranteed VOH/VOL, tPD, or drive specifications-and is explicitly rated only for "data retention" below 1.65V. Use only within 1.65–5.5V for functional logic operation.
Is the NC pin on SOT25 package internally connected?
No. Pin 3 in the SOT25 top-view diagram is labeled "NC" (No Connection) and is not bonded to any internal die structure. It must remain unconnected on the PCB; soldering or routing to this pad has no electrical effect and risks mechanical stress or shorting if misaligned.
Does 74LVC1G08W5-7 support 5V logic inputs when VCC = 1.8V?
Yes. Inputs tolerate up to 5.5V regardless of VCC level, as confirmed in Absolute Maximum Ratings (VI = –0.5 to 6.5V) and Features ("Inputs Accept Up to 5.5V"). This allows safe interfacing with 5V microcontrollers driving a 1.8V domain, provided output loading remains within drive capability.
What is the thermal resistance (θJA) for SOT25 package?
The junction-to-ambient thermal resistance for the SOT25 package is 204°C/W under standard test conditions: mounted on FR-4 board with 2oz copper and Diodes' recommended pad layout. This value assumes natural convection; actual θJA improves with added copper area or airflow, and degrades with poor layout or enclosed enclosures.
