Product details
Overview
74LVC1G08FX4-7 from Diodes Incorporated is a single 2-input positive AND gate in a 6-pin X2-DFN1409-6 chip-scale package, operating from 1.65V to 5.5V 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 and I²C signal conditioning.
For engineers reviewing the 74LVC1G08FX4-7 datasheet, 74LVC1G08FX4-7 pinout, 74LVC1G08FX4-7 application, or 74LVC1G08FX4-7 equivalent, key selection criteria include its 1.4mm × 0.9mm footprint, IOFF-enabled isolation during system sleep states, input voltage tolerance beyond VCC, and propagation delay of 2.1ns (typ) at 3.3V.
Technical Context
This device implements standard Boolean AND logic (Y = A · B) using CMOS technology with push-pull outputs and no internal pull-ups or pull-downs. Its IOFF feature actively disables output leakage when VCC = 0V, preventing back-current flow in powered-down subsystems.
Input thresholds are voltage-ratio-based (e.g., VIH ≥ 0.65×VCC for 1.65–1.95V operation), enabling reliable interfacing across 1.8V, 2.5V, 3.3V, and 5V logic domains. ESD protection exceeds 2kV HBM and 1kV CDM, meeting industrial-grade robustness requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports direct interface between 1.8V/2.5V/3.3V/5V logic families without level shifters |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage signals even when VCC is at 1.65V |
| IOFF Leakage Current | ±200μA max at -40°C to +125°C - ensures signal isolation during partial power-down |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC/LVT inputs or small capacitive loads (<30pF) |
| Propagation Delay | 2.1ns typical at VCC = 3.3V - enables use in high-speed control paths up to ~100MHz toggle rate |
| Input Capacitance | 5pF typical - minimizes loading on upstream drivers in dense PCB layouts |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM - meets JEDEC JESD22-A114/A115/C101 for board-level reliability |
Pinout & Package
X2-DFN1409-6 is a 1.4mm × 0.9mm × 0.4mm chip-scale package with 6 solder pads on bottom; no leads; requires controlled thermal pad layout per Diodes Inc. recommended footprint (C = 1.000mm, G = 0.200mm, X = 0.400mm, Y = 0.150mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First logic input; accepts 0V to 5.5V regardless of VCC value |
| B | Data Input | Second logic input; identical voltage tolerance and threshold behavior as Pin A |
| GND | Ground Reference | Primary return path for supply current and output switching; must be low-impedance |
| VCC | Power Supply | Core supply rail (1.65–5.5V); powers internal logic and output stage |
| Y | Data Output | Push-pull CMOS output; sinks or sources current per logic state; no open-drain behavior |
| NC | No Connection | Unbonded die pad; must be left floating or connected to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Enables single part number deployment across 1.8V microcontroller I/O, 3.3V FPGA banks, and 5V legacy peripherals |
| IOFF partial power-down | Prevents destructive back-current when VCC is off but inputs remain active - critical for hot-swap and battery-backed subsystems |
| 5.5V-tolerant inputs | Eliminates need for external resistive dividers when interfacing 5V sensors or switches to low-voltage controllers |
| Low dynamic power (16pF Cpd) | Reduces switching noise and supply ripple in high-density logic arrays operating at >10MHz |
| Lead-free & halogen-free | Fully RoHS 2 compliant with <900ppm Br+Cl and <1000ppm Sb - suitable for consumer and medical end equipment |

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 logic function and IOFF, but in SOT-23-5 (5-pin) package with different pinout (no NC pin) | Requires PCB redesign due to 5-pin vs 6-pin layout and missing NC terminal | Select if board space allows larger SOT-23 footprint and NC functionality is unnecessary |
| 74LVC1G08GW,125 | NXP variant in SOT363-6 package; identical electrical specs but different thermal resistance (θJA = 371°C/W vs 470°C/W) | Higher power dissipation capability in continuous operation; less sensitive to local heating | Prefer for thermally constrained environments where junction temperature rise must be minimized |
Compared with SN74LVC1G08DBVR and 74LVC1G08GW,125, the 74LVC1G08FX4-7 offers the smallest footprint (1.26mm²) and highest input voltage tolerance margin (5.5V vs VCC+0.5V), making it optimal for ultra-compact, mixed-voltage portable designs where thermal headroom is secondary to area savings.

FAQ
Can 74LVC1G08FX4-7 operate reliably at 1.65V supply?
Yes. The device is fully specified down to 1.65V VCC, with guaranteed VOH ≥ VCC – 0.1V and VOL ≤ 0.45V at –40°C to +85°C under 4mA load. Input thresholds scale with VCC (VIH ≥ 0.65×VCC), ensuring noise margins remain valid across the entire supply range.
What is the function of the NC pin in X2-DFN1409-6?
The NC (No Connection) pin is an unconnected die pad with no internal bond wire. Per Diodes Inc. layout guidance, it may be left floating or tied to GND to improve thermal conduction and mechanical stability - but must never be connected to VCC or signal nets.
Does IOFF protect against reverse current when only one supply rail is powered?
Yes. IOFF activates whenever VCC is near 0V (≤0.2V), disabling both output FETs regardless of input voltage. This prevents current flow from a live 5.5V input into a grounded output node, satisfying JEDEC JESD78 latch-up immunity requirements.
How does thermal performance compare between X2-DFN1409-6 and SOT25 packages?
X2-DFN1409-6 has θJA = 470°C/W versus 204°C/W for SOT25 under identical FR-4 test conditions. While the chip-scale package saves area, its higher thermal resistance means lower maximum continuous power dissipation - limit ambient temperature or add copper pour if operating above 25°C with >1mA average output current.
