Nexperia USA Inc. 74LVC1G99GF,115

Overview

74LVC1G99GF,115 from Nexperia is an ultra-configurable single-gate logic IC with 3-state output, Schmitt-trigger inputs, and configurable logic functions (AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer, MUX) via direct VCC/GND pin strapping. It operates from 1.65 V to 5.5 V, supports mixed-voltage interfacing with 5 V tolerant inputs, and delivers ±24 mA output drive at 3.0 V - used in space-constrained board-level logic reconfiguration and voltage-level translation.

For engineers reviewing the 74LVC1G99GF,115 datasheet, 74LVC1G99GF,115 pinout, 74LVC1G99GF,115 application, or 74LVC1G99GF,115 equivalent, key selection criteria include its 8-pin XSON package footprint, IOFF power-down protection, Schmitt-trigger noise immunity, and support for partial power-down in battery-backed or hot-swap systems.

Technical Context

The device implements a programmable logic cell using four Schmitt-trigger inputs (A–D), one active-low output enable (OE), and a single 3-state output (Y). Configuration is achieved by hardwiring A–D to VCC or GND - no external components or configuration registers required.

Its IOFF circuit blocks backflow current during power-down, and input overvoltage tolerance (up to 5.5 V) enables safe interfacing across 1.65 V–5.5 V supply domains without level shifters. The hysteresis (VH = 0.30–1.40 V, depending on VCC) ensures clean signal regeneration from slow or noisy inputs.

FAQ

What logic functions can be implemented with the 74LVC1G99GF,115?

The 74LVC1G99GF,115 supports 18 distinct logic configurations including AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer, and 2-input multiplexer - selected by hardwiring its four Schmitt-trigger inputs (A–D) to VCC or GND. No external programming or clocking is needed; all functions are static and deterministic once strapped.

Does the 74LVC1G99GF,115 require external pull-up or pull-down resistors for configuration?

No. The device accepts direct connections of A–D inputs to VCC or GND for configuration - internal input structures eliminate the need for external resistors. This simplifies layout, reduces component count, and avoids resistor tolerance or leakage effects that could compromise function selection.

How does the IOFF feature protect the device during power-down?

When VCC = 0 V, the IOFF circuit disables both inputs and the output, limiting leakage current to ±2 μA maximum. This prevents back-current flow from live signal lines into a powered-down domain - protecting downstream circuitry and meeting IEC 61000-4-2 and ISO 11898-2 requirements for automotive and industrial systems.

Can the 74LVC1G99GF,115 interface directly with 5 V TTL outputs?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), enabling direct connection to standard 5 V TTL outputs without level-shifting circuitry. The device maintains valid logic thresholds and hysteresis across the full supply range, ensuring reliable signal interpretation.
