Product details
Overview
74LVC1G98DW-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in SOT363 package, supporting eight logic configurations (MUX, AND, OR, NAND, NOR, inverter, buffer) via input pin states. It operates from 1.65V to 5.5V, features ±24mA output drive at 3.3V, 5.1ns max propagation delay at 5V, and IOFF-enabled partial power-down protection. Used for voltage-level shifting and signal routing in portable computing peripherals.
For engineers reviewing the 74LVC1G98DW-7 datasheet, 74LVC1G98DW-7 pinout, 74LVC1G98DW-7 application, or 74LVC1G98DW-7 equivalent, this device serves as a space-saving, mixed-voltage-compatible logic configurator with Schmitt-trigger input hysteresis, IOFF isolation, and RoHS-compliant DFN/SOT packaging options.
Technical Context
The 74LVC1G98DW-7 implements a 3-bit truth table mapping (IN2/IN1/IN0 → Y) to select among seven standard logic functions plus multiplexer mode. Its inputs exhibit Schmitt-trigger action with hysteresis (0.30–1.40V depending on VCC), enabling noise immunity in noisy digital environments.
IOFF circuitry actively disables output during power-down, blocking backflow current when VCC = 0V while inputs remain at up to 5.5V - critical for hot-swap and partial-power-down system architectures. Input tolerance to 5.5V allows interoperability across 1.8V, 2.5V, 3.3V, and 5V domains without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic families. |
| Max Propagation Delay | 5.1ns at VCC = 5V, CL = 50pF - enables high-speed signal routing in timing-critical paths. |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC loads or moderate capacitive traces. |
| Input Hysteresis (ΔVT) | 0.30–1.40V - improves noise margin and prevents chatter on slow-rising signals. |
| IOFF Leakage Current | ±200μA at TA = –40°C to +125°C - ensures safe bus hold and isolation during power sequencing. |
| ESD Protection | 2kV HBM, 200V MM - exceeds JEDEC standards for robust handling in manufacturing and field use. |

Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Function | Selects MUX, AND, OR, NAND, NOR, inverter, or buffer via static IN0/IN1/IN2 states - eliminates need for multiple fixed-function gates. |
| IOFF Partial Power-Down | Disables output and blocks current flow when VCC = 0V, preventing backfeeding into powered subsystems during hot-plug or sleep modes. |
| 5.5V-Tolerant Inputs | Accepts 0–5.5V input signals regardless of VCC setting - enables seamless interfacing between disparate voltage domains without external translators. |
| Schmitt-Trigger Inputs | Provides 0.30–1.40V hysteresis to reject noise on slow or degraded edges - critical for reliable operation in noisy PCB environments. |
| Low Dynamic Power | 23pF typical power dissipation capacitance at 3.3V/10MHz - reduces switching current and heat generation in battery-powered devices. |
Applications
| USB Peripheral Interface | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Level-shifting and signal routing between 3.3V microcontroller GPIO and 5V USB transceiver control lines. IC Role / Device Role / Timing Role: Configured as non-inverting buffer to pass VBUS detection or pull-up enable signals with 5.5V-tolerant input and 3.3V-compatible output. Use Value: Eliminates discrete level shifter ICs; IOFF prevents backfeed during USB suspend when MCU is powered down. |
Use Scenario: Interfacing noisy analog sensor outputs (e.g., thermistor divider) to a 1.8V ADC controller in factory automation equipment. IC Role / Device Role / Timing Role: Configured as Schmitt-trigger inverter to clean up slow-rising sensor threshold crossings before digitization. Use Value: Hysteresis (≥0.62V at 3V) rejects EMI-induced glitches; low ICC (≤200μA) minimizes standby power in always-on monitoring nodes. |
| Portable Display Backlight Control | Automotive Infotainment I/O Expansion |
|
Use Scenario: Driving LED backlight enable/disable logic in tablets where main SoC runs at 1.2V but display driver requires 3.3V-level signals. IC Role / Device Role / Timing Role: Configured as OR gate to combine multiple low-voltage enable sources into one 3.3V-compatible output. Use Value: Wide VCC range (1.65–5.5V) allows direct 3.3V supply; ±24mA drive handles LED driver input capacitance without buffering. |
Use Scenario: Adding flexible logic gating for CAN/LIN transceiver enable signals in head unit designs with mixed 3.3V/5V subsystems. IC Role / Device Role / Timing Role: Configured as NAND gate to generate active-low enable based on two independent control bits. Use Value: IOFF protects LIN bus during MCU reset; 125°C rating ensures reliability under dashboard temperature extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G98DBVR | Texas Instruments variant in SOT-23-6; identical logic function and electrical specs, but IOFF leakage rated at ±10μA (TA ≤ 85°C) vs. ±200μA (TA ≤ 125°C) for Diodes' part. | Better suited for commercial-temperature consumer apps; less robust for industrial thermal cycling. | Choose SN74LVC1G98DBVR only if operating ambient stays below 85°C and tighter IOFF leakage is required. |
| 74AUP1G98GW,125 | Nexperia AUP-family version in TSSOP6; lower ICC (10μA typ), slower tPD (11.5ns @ 3.3V), and narrower VCC range (0.8–3.6V). | Optimized for ultra-low-power battery operation but incompatible with 5V systems or high-speed routing. | Select 74AUP1G98GW,125 only for sub-3.6V, sub-100kHz applications where quiescent current dominates design priority. |
Compared with SN74LVC1G98DBVR and 74AUP1G98GW,125, the 74LVC1G98DW-7 uniquely balances wide voltage operation (1.65–5.5V), industrial temperature support (–40°C to +125°C), and robust IOFF isolation - making it the preferred choice for mixed-voltage, thermally demanding embedded control nodes.

FAQ
What logic functions can the 74LVC1G98DW-7 implement?
The 74LVC1G98DW-7 implements eight distinct logic behaviors determined by its three inputs (IN2/IN1/IN0): MUX, AND, OR, NAND, NOR, inverter, non-inverting buffer, and a 2-to-1 data selector with inverted output. Each combination maps directly to a row in the truth table provided in the datasheet - no external programming or configuration registers are needed.
Does the 74LVC1G98DW-7 support hot-swap or partial power-down operation?
Yes - the device includes an IOFF circuit that automatically disables the output and blocks current backflow when VCC is removed or near zero, even if inputs remain at up to 5.5V. This feature is fully specified per JESD78 Class II latch-up testing and enables safe use in hot-plug interfaces and multi-rail power sequencing scenarios.
Can the 74LVC1G98DW-7 be used for level shifting between 1.8V and 5V domains?
Yes - its 5.5V-tolerant inputs accept signals up to 5.5V regardless of VCC setting, and its output swings rail-to-rail between GND and VCC. When powered at 1.8V, it safely reads 5V inputs and drives 1.8V-compatible loads; when powered at 5V, it reads 1.8V inputs (above VT− min of 0.30V) and drives 5V loads.
Is the SOT363 package of the 74LVC1G98DW-7 lead-free and RoHS compliant?
Yes - the 74LVC1G98DW-7 uses a "Green" molding compound with no intentionally added lead, bromine, chlorine, or antimony. It meets EU Directive 2011/65/EU (RoHS 2), contains <900ppm Br, <900ppm Cl, <1000ppm Sb, and is fully halogen-free and lead-free per Diodes Incorporated's AP02001 specification.
