Product details
Overview
SN74LVC2G00DCUTG4 from Texas Instruments is a dual 2-input positive-NAND gate IC operating from 1.65 V to 5.5 V, delivering 24-mA output drive at 3.3 V, with 4.3-ns propagation delay and Ioff partial-power-down protection. It performs Boolean Y = A × B on two independent gates and is used in telecom baseband units and optical networking signal conditioning.
For engineers reviewing the SN74LVC2G00DCUTG4 datasheet, SN74LVC2G00DCUTG4 pinout, SN74LVC2G00DCUTG4 application, or SN74LVC2G00DCUTG4 equivalent, key selection criteria include 5.5-V tolerant inputs, ±24-mA drive capability at 3.3 V, Ioff-enabled live insertion support, and VSSOP-8 (DCU) package compatibility with high-density PCB layouts.
Technical Context
The SN74LVC2G00DCUTG4 implements two independent CMOS NAND gates with rail-to-rail input voltage tolerance up to 5.5 V and output swing from GND to VCC. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-current flow during hot-swap or partial power-down scenarios.
Each gate follows standard positive-logic NAND truth table behavior (H,H→L; L,X→H; X,L→H), supports 100-MHz operation under light loads, and exhibits low ground bounce (VOLP < 0.8 V) and undershoot (VOHV > 2 V) at 3.3 V, enabling clean signal integrity in high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. |
| tpd (Max) | 4.3 ns at VCC = 3.3 V - Supports reliable timing in sub-100-MHz digital control paths. |
| IOL / IOH | ±24 mA at VCC = 3.3 V - Drives multiple 74LVC inputs or LEDs directly without buffering. |
| Ioff Current | ±10 μA max - Ensures safe isolation during power sequencing and hot-plug events. |
| Input Voltage Tolerance | 0 V to 5.5 V - Allows level translation from higher-voltage controllers into lower-VCC logic systems. |
| ESD Rating | 2000-V HBM - Meets industrial-grade robustness requirements for board-level handling and deployment. |
| Operating Temp | –40°C to +125°C - Qualified for extended-temperature telecom and infrastructure applications. |
Pinout & Package
VSSOP-8 (DCU) package: 2.30 mm × 2.00 mm body, 0.5-mm lead pitch, 0.9-mm max height, exposed pad not present, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Gate 1 | Accepts 0–5.5 V; must be tied to VCC or GND if unused to prevent floating logic states. |
| 1B | Input B of Gate 1 | Independent NAND input; shares no internal connection with Gate 2 inputs. |
| 2Y | Output Y of Gate 2 | Active-low NAND output; sinks or sources up to ±24 mA at 3.3 V. |
| GND | Ground Reference | Primary return path for all logic and output currents; requires low-impedance PCB plane. |
| 2A | Input A of Gate 2 | Electrically isolated from Gate 1; supports independent logic functions per gate. |
| 2B | Input B of Gate 2 | 5.5-V tolerant; compatible with mixed-voltage system interfacing. |
| 1Y | Output Y of Gate 1 | Provides complementary NAND result to 1A/1B; identical drive strength and timing as 2Y. |
| VCC | Power Supply Input | Supplies both gates; requires local 0.1-μF bypass capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ Packaging | Dies-as-package construction reduces footprint to 2.30 mm × 2.00 mm - ideal for space-constrained telecom modules. |
| Ioff Partial-Power-Down | Enables live insertion and back-drive protection by disabling outputs when VCC = 0 V - critical for modular chassis designs. |
| 5.5-V Input Tolerance | Allows interface with legacy 5-V microcontrollers while operating at 1.8-V or 3.3-V VCC - eliminates external level shifters. |
| Low ICC (10 μA Max) | Minimizes quiescent power in always-on monitoring circuits such as remote radio unit status logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G00DCUR | Same silicon, identical electrical specs, VSSOP-8 (DCU) package, NIPDAU finish, 3000-unit reel. | Higher volume procurement; same PCB layout but different tape-and-reel packaging. | Select SN74LVC2G00DCUR for production runs ≥3000 units; SN74LVC2G00DCUTG4 suits prototyping and low-volume builds (250-unit reel). |
| SN74AHC2G00DCUR | Higher VCC range (2–5.5 V), faster tpd (2.5 ns @ 5 V), higher ICC (40 μA), no Ioff support. | Lacks Ioff and 1.65-V operation; unsuitable for partial-power-down or ultra-low-VCC systems. | Choose SN74AHC2G00DCUR only when 5-V operation and maximum speed are required, and Ioff is not needed. |
Compared with SN74LVC2G00DCUR, SN74LVC2G00DCUTG4 offers identical functionality in the same VSSOP-8 package but optimized for small-batch deployment; versus SN74AHC2G00DCUR, it trades raw speed for broader voltage range, lower static power, and essential Ioff protection in modern modular infrastructure.

FAQ
What is the maximum operating voltage for SN74LVC2G00DCUTG4?
The SN74LVC2G00DCUTG4 supports a VCC range of 1.65 V to 5.5 V. Its absolute maximum supply voltage is 6.5 V, but sustained operation above 5.5 V violates recommended conditions and risks reliability degradation. All electrical characteristics-including propagation delay, drive strength, and noise margins-are guaranteed only within the 1.65–5.5-V window specified in the datasheet.
Does SN74LVC2G00DCUTG4 support partial power-down functionality?
Yes, SN74LVC2G00DCUTG4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap or partial-power-down events. This feature is explicitly characterized in the datasheet with Ioff ≤ ±10 μA across –40°C to 125°C and enables safe live insertion in modular telecom systems.
What is the pin configuration of SN74LVC2G00DCUTG4?
SN74LVC2G00DCUTG4 uses an 8-pin VSSOP (DCU) package with top-view pinout: Pin 1 = 1A, Pin 2 = 1B, Pin 3 = 2Y, Pin 4 = GND, Pin 5 = 2A, Pin 6 = 2B, Pin 7 = 1Y, Pin 8 = VCC. This matches the standardized DCU footprint and is verified in TI's mechanical drawing DCU0008A.
Can SN74LVC2G00DCUTG4 interface with 5-V logic inputs while running at 3.3 V?
Yes, SN74LVC2G00DCUTG4 inputs tolerate voltages up to 5.5 V regardless of VCC level-enabling direct connection to 5-V microcontrollers or sensors while operating at 3.3 V. This eliminates external level shifters and is confirmed in the "Inputs Accept Voltages to 5.5 V" feature and VI specification (0–5.5 V) in the datasheet.
What is the typical propagation delay of SN74LVC2G00DCUTG4 at 3.3 V?
The typical propagation delay (tpd) of SN74LVC2G00DCUTG4 is 4.3 ns at VCC = 3.3 V, TA = 25°C, with a maximum of 4.9 ns over the full –40°C to +125°C range. This value is measured under standard load conditions (CL = 50 pF, ΔV = ±0.3 V) and applies to both gates independently.
