Texas Instruments SN74LVC1G98YEAR

Overview

SN74LVC1G98YEAR 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). It delivers 6.3 ns max propagation delay at 3.3 V, ±24 mA output drive, and Schmitt-trigger inputs for noise immunity. Used in level-shifting I/O interfaces and reconfigurable logic blocks in space-constrained industrial controllers.

For engineers reviewing the SN74LVC1G98YEAR datasheet, SN74LVC1G98YEAR pinout, SN74LVC1G98YEAR application, or SN74LVC1G98YEAR equivalent, key selection criteria include its 6-pin NanoFree™ DSBGA (YZP) package, Ioff support for live insertion, hysteresis-enabled input threshold stability (VT+ = 2.61 V / VT– = 1.87 V at 5.5 V), and compatibility with mixed-voltage systems up to 5.5 V on inputs.

Technical Context

The SN74LVC1G98YEAR implements a 3-input lookup table architecture where In0–In2 select one of eight logic functions mapped to output Y. Its Schmitt-trigger inputs provide asymmetric thresholds (ΔVT ≥ 0.71 V at 5.5 V), enabling robust operation in noisy environments. All inputs tolerate voltages up to 5.5 V independent of VCC, supporting down-translation from higher-voltage domains.

It features Ioff circuitry that disables outputs during partial power-down, preventing back-drive current when VCC = 0 V. The device is fully specified across –40°C to +125°C and supports 10 µA max ICC, making it suitable for low-power battery-backed and thermally demanding embedded applications.

FAQ

What logic functions can SN74LVC1G98YEAR implement?

SN74LVC1G98YEAR implements eight logic functions determined by its three inputs (In0–In2): 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 configuration is defined in the device's function table and verified across the full operating temperature range.

Does SN74LVC1G98YEAR support level translation between different supply voltages?

Yes, SN74LVC1G98YEAR supports down-translation: its inputs accept voltages up to 5.5 V regardless of VCC value (1.65 V to 5.5 V), allowing direct connection to 5 V peripherals while operating from 1.8 V or 3.3 V supplies. Output swing follows VCC, ensuring compatible logic levels for downstream receivers.

What is the purpose of the Schmitt-trigger inputs in SN74LVC1G98YEAR?

The Schmitt-trigger inputs in SN74LVC1G98YEAR provide hysteresis (ΔVT ≥ 0.71 V at 5.5 V), meaning VT+ and VT– thresholds differ significantly. This prevents oscillation on slow-rising or noisy signals - critical for reliable operation when interfacing with mechanical switches, analog comparators, or unfiltered sensor outputs in industrial environments.

Can SN74LVC1G98YEAR be used in hot-swap or partial-power-down systems?

Yes, SN74LVC1G98YEAR includes Ioff circuitry that actively disables outputs when VCC = 0 V. This prevents damaging current backflow through the device during live insertion or when other system rails remain active - a key requirement for modular backplane and hot-pluggable peripheral designs.

What package type does SN74LVC1G98YEAR use, and what are its key mechanical advantages?

SN74LVC1G98YEAR uses the 6-ball DSBGA (YZP) NanoFree™ package: 1.4 mm × 1.4 mm footprint, 0.5 mm max height, bottom-terminal ball grid. Its die-as-package construction eliminates leadframe parasitics, improves thermal performance (θJA = 123°C/W), and enables ultra-thin PCB stacking in wearables and compact IoT modules.
