Nexperia USA Inc. 74LVC1G99GN,115

Overview

74LVC1G99GN,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, signal conditioning, and reconfigurable I/O interfaces in space-constrained industrial controllers.

For engineers reviewing the 74LVC1G99GN,115 datasheet, 74LVC1G99GN,115 pinout, 74LVC1G99GN,115 application, or 74LVC1G99GN,115 equivalent, this page provides verified functional configuration modes, Schmitt-trigger hysteresis values, IOFF power-down behavior, and XSON8 package layout details essential for mixed-voltage board design and partial-power-down compliance.

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 required - enabling selection among 18+ logic functions per Table 5–20. All configurations retain 3-state control via OE.

Its Schmitt-trigger inputs provide hysteresis (e.g., 0.48 V typical at VCC = 1.8 V) to reject noise on slow-rising/falling signals, while IOFF circuitry blocks backflow current during power-down. Inputs tolerate up to 5.5 V regardless of VCC, supporting robust interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.

FAQ

What logic functions can be implemented with the 74LVC1G99GN,115?

The 74LVC1G99GN,115 supports 18+ logic configurations including AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer, and 2-input multiplexer - selected by strapping inputs A–D to VCC or GND. Each configuration retains 3-state output control via OE, and all modes are defined in Tables 5–20 of the official datasheet Rev. 13.

Does the 74LVC1G99GN,115 require external pull-up or pull-down resistors for configuration?

No. The device uses internal weak pull-up/pull-down structures compatible with direct VCC/GND connections for A–D pins. External resistors are unnecessary and not recommended - strapping is done with solid short connections to supply or ground rails per the function selection tables.

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

When VCC = 0 V, the IOFF circuit disables both inputs and output, limiting leakage current to ±2 μA maximum. This prevents back-current flow from live 5 V buses into a powered-down domain - critical for hot-swap systems, multi-rail power sequencing, and battery-backed subsystems.

Is the 74LVC1G99GN,115 pin-compatible with other XSON8 logic devices?

No. While the SOT1116 XSON8 footprint is standardized, pin assignments differ across logic families. The 74LVC1G99GN,115 has unique pinout (OE-A-B-GND-C-D-Y-VCC) confirmed in Figure aaa-037253; substitution requires schematic and layout revision, not drop-in replacement.
