Nexperia USA Inc. 74LVC1G99GS,115

Overview

74LVC1G99GS,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 -40 °C to +125 °C, and delivers ±24 mA drive at 3.0 V - used in voltage-level translation and reconfigurable signal routing in space-constrained industrial controllers.

For engineers reviewing the 74LVC1G99GS,115 datasheet, 74LVC1G99GS,115 pinout, 74LVC1G99GS,115 application, or 74LVC1G99GS,115 equivalent, key selection criteria include its 8-pin XSON package footprint, IOFF-enabled partial power-down capability, Schmitt-trigger noise immunity, and 5 V tolerant inputs enabling mixed-voltage interface design without external components.

Technical Context

The 74LVC1G99 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 programming interface or non-volatile memory is involved.

Its IOFF circuit disables output leakage during power-down, and input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V systems while powered from 1.8 V or 3.3 V rails. Propagation delay ranges from 1.6 ns (VCC = 5.5 V) to 30.8 ns (VCC = 1.8 V), with hysteresis (VH) of 0.30–1.40 V depending on supply.

FAQ

What logic functions can be implemented with the 74LVC1G99GS,115?

The 74LVC1G99GS,115 supports 16+ configurable logic functions including AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer, and 2-input multiplexer - selected by hardwiring its four inputs (A–D) to VCC or GND. No external configuration circuitry or programming is required, and all functions operate with full 3-state output control via OE.

Does the 74LVC1G99GS,115 require external pull-up or pull-down resistors?

No. The 74LVC1G99GS,115 has no internal weak pull-ups or pull-downs, but its inputs accept direct connection to VCC or GND for configuration - eliminating need for external resistors. Input leakage is ±0.1 μA max, ensuring stable logic levels without additional biasing components.

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

When VCC = 0 V, the IOFF circuit disables both inputs and output, limiting leakage current to ±2 μA maximum - preventing damaging back-current flow through the device from live signal lines into unpowered sections of the system, a critical requirement in hot-swap and multi-rail architectures.

Can the 74LVC1G99GS,115 be used with 5 V microcontrollers while powered from 3.3 V?

Yes. Its inputs are 5 V tolerant up to 5.5 V regardless of VCC, allowing direct connection to 5 V MCU GPIOs or peripherals while operating from a 3.3 V supply. Output voltage swing remains rail-to-rail (0 V to 3.3 V), so level-shifting may be needed if driving 5 V inputs - but input-side compatibility is guaranteed.
