Product details
Overview
SN74LVC1G98DCKR from Texas Instruments is a configurable multiple-function logic gate operating from 1.65 V to 5.5 V, supporting MUX, AND, OR, NAND, NOR, inverter, and noninverter functions via three digital inputs (In0–In2) and one output (Y). It features Schmitt-trigger inputs with hysteresis (ΔVT = 0.53 V typ at 3 V), 6.3 ns max propagation delay at 3.3 V, ±24 mA output drive, and Ioff support for live insertion. Used in level-shifting interface logic and noise-immune signal conditioning in portable and industrial control systems.
For engineers reviewing the SN74LVC1G98DCKR datasheet, SN74LVC1G98DCKR pinout, SN74LVC1G98DCKR application, or SN74LVC1G98DCKR equivalent, this page delivers verified functional configuration modes, SC70-6 package mechanical data, absolute maximum ratings, switching characteristics across VCC, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The SN74LVC1G98DCKR implements a 3-input programmable logic cell where the output Y is determined by an 8-row function table mapping In2/In1/In0 combinations to high or low states. Its Schmitt-trigger inputs provide distinct VT+ (1.5 V typ) and VT– (0.84 V typ) thresholds at 3 V, enabling robust noise rejection in slow-rising or noisy environments.
It supports voltage translation: inputs tolerate up to 5.5 V independent of VCC, and outputs drive rail-to-rail within VCC. The Ioff feature disables outputs during partial power-down, preventing back-current flow when VCC = 0 V - critical for hot-swap and multi-rail system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| tpd (max) | 6.3 ns at VCC = 3.3 V - ensures timing compliance in high-speed digital control paths. |
| Output Drive | ±24 mA at VCC = 3 V - directly drives LEDs, small relays, or fanout to ≥10 LVC loads. |
| Input Hysteresis ΔVT | 0.53 V typical at 3 V - rejects >500 mV of input noise without external filtering. |
| Ioff Current | ±10 µA max - blocks damaging backflow during power sequencing or hot-plug events. |
| ESD Rating | 2000-V HBM - meets industrial IEC 61000-4-2 Level 2 immunity requirements. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments. |
Pinout & Package
SN74LVC1G98DCKR uses the SC70-6 (DCK) package: 2.0 mm × 1.25 mm footprint, 1.1 mm max height, 0.65 mm lead pitch, and pin 1 marked by a dot or beveled edge. Thermal resistance θJA = 259 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In0 | Primary logic input; referenced in function table as LSB of 3-bit control word. |
| 2 | In1 | Secondary logic input; middle bit of 3-bit control word determining gate behavior. |
| 3 | In2 | Control input; MSB of 3-bit word selecting among eight logic configurations. |
| 4 | GND | Ground reference for all internal circuitry and output swing reference. |
| 5 | VCC | Power supply input; sets output voltage swing and defines logic threshold levels. |
| 6 | Y | Configurable output; state determined by In2/In1/In0 combination per function table. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Function | Selects among 8 modes (MUX, AND, OR, NAND, NOR, inverter, buffer) using only 3 pins - eliminates need for multiple discrete gates. |
| Schmitt-Trigger Inputs | VT+ = 1.5 V / VT– = 0.84 V at 3 V - enables reliable operation with slow or noisy signals without external hysteresis components. |
| Voltage Translation | Inputs accept 0–5.5 V regardless of VCC - allows interfacing 5 V sensors to 3.3 V microcontrollers without level shifters. |
| Ioff Protection | Outputs enter high-Z when VCC = 0 V - prevents current backflow during power sequencing or board hot-swap. |
| NanoFree™ Packaging | DCK package uses die-as-package construction - reduces parasitic inductance and improves thermal performance vs. standard SC70. |
Applications
| Industrial Sensor Interface | Portable Power Sequencing |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, pressure transducer) before ADC sampling in PLC modules. IC Role / Device Role / Timing Role: Configured as inverter or buffer with Schmitt input to reject EMI-induced glitches on long traces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G57DCKR | Same SC70-6 package, identical VCC range and Ioff, but lacks Schmitt-trigger inputs (standard CMOS thresholds). | Not suitable for noisy or slow-rising signals; requires external filtering for switch debouncing or sensor interfaces. | Choose when cost sensitivity outweighs noise immunity needs and input edges are clean. |
| NC7SZ57P5X | SC70-5 package (5-pin), supports same logic functions but no VCC-independent input tolerance (max VI = VCC + 0.5 V). | Cannot translate 5 V signals into 3.3 V systems; limited to single-supply domain use cases. | Prefer when board space is constrained and all signals share the same VCC domain. |
Compared with SN74LVC1G57DCKR and NC7SZ57P5X, SN74LVC1G98DCKR uniquely combines Schmitt-trigger noise immunity, 5.5 V-tolerant inputs, and full Ioff protection - making it the only choice for mixed-voltage, high-noise, or hot-swap-critical applications.

FAQ
What logic functions does the SN74LVC1G98DCKR support?
The SN74LVC1G98DCKR supports eight configurable logic functions selected via its three inputs (In2/In1/In0): 2-to-1 data selector with inverted output, 2-input NAND, 2-input NOR with one inverted input, 2-input AND with one inverted input, 2-input NAND with one inverted input, 2-input OR with one inverted input, 2-input NOR, noninverted buffer, and inverter. Each mode is defined in the function table of the official datasheet SCES417L.
Does the SN74LVC1G98DCKR support level translation between different voltage domains?
Yes, the SN74LVC1G98DCKR supports down-translation: its inputs accept voltages up to 5.5 V regardless of VCC (1.65 V to 5.5 V), allowing 5 V signals to safely interface with a 3.3 V or 1.8 V powered SN74LVC1G98DCKR. Outputs swing rail-to-rail within the applied VCC, enabling clean signal transfer across domains without external translators.
What is the purpose of the Ioff feature in the SN74LVC1G98DCKR?
The Ioff feature disables the output drivers when VCC = 0 V, placing them in high-impedance state. This prevents current backflow through the device when it is powered down while other system components remain active - essential for hot-swap capability, partial power-down modes, and avoiding damage during improper power sequencing in multi-rail systems using SN74LVC1G98DCKR.
Can the SN74LVC1G98DCKR be used for switch debouncing?
Yes, the SN74LVC1G98DCKR is well-suited for mechanical switch debouncing due to its built-in Schmitt-trigger inputs, which provide hysteresis (ΔVT = 0.53 V typ at 3 V). When configured as a buffer or inverter, it cleanly converts noisy, slow-rising switch transitions into sharp, glitch-free digital edges - eliminating the need for external RC networks or firmware debouncing delays in designs using SN74LVC1G98DCKR.
What package type is used for the SN74LVC1G98DCKR?
The SN74LVC1G98DCKR uses the SC70-6 (DCK) package: a 6-pin, surface-mount plastic small-outline transistor package measuring 2.0 mm × 1.25 mm with 0.65 mm lead pitch and 1.1 mm maximum height. It is RoHS-compliant, moisture-sensitivity level 1, and compatible with standard reflow soldering profiles per JEDEC J-STD-020.
