Nexperia USA Inc. 74LVC1G99GT,115

Overview

74LVC1G99GT,115 from Nexperia is an ultra-configurable single-gate logic IC with Schmitt-trigger inputs, 3-state output, and configurable function selection (AND/OR/NAND/NOR/XOR/XNOR/inverter/buffer/MUX) via direct VCC/GND connection of inputs A–D. 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 mixed-voltage I/O interfacing.

For engineers reviewing the 74LVC1G99GT,115 datasheet, 74LVC1G99GT,115 pinout, 74LVC1G99GT,115 application, or 74LVC1G99GT,115 equivalent, key selection criteria include its 8-pin XSON8 package, IOFF power-down protection, 5 V tolerant inputs, Schmitt-trigger noise immunity, and functional reconfigurability without external components.

Technical Context

The 74LVC1G99GT implements a single ultra-flexible logic gate with four Schmitt-trigger data inputs (A–D), one active-low output enable (OE), and a 3-state output (Y). Its configuration is determined by static logic levels applied to A–D - no internal programming or clock required.

All logic functions are realized combinatorially using the same core gate structure; function selection relies on fixed input biasing (e.g., tying C/D to VCC/GND), enabling deterministic behavior across AND, OR, XOR, MUX, and inverting variants - all with identical propagation delay profiles and hysteresis thresholds (VT+ = 1.50 V, VT− = 0.80 V at VCC = 3.0 V).

FAQ

What logic functions can the 74LVC1G99GT,115 be configured to perform?

The 74LVC1G99GT,115 supports 16 distinct logic configurations including AND, OR, NAND, NOR, XOR, XNOR, inverter, buffer, and 2-input multiplexer - selected by hardwiring inputs A–D to VCC or GND. No external components or programming are needed; all functions operate with identical timing and drive strength.

Does the 74LVC1G99GT,115 require external pull-up or pull-down resistors for configuration?

No. The 74LVC1G99GT,115 accepts direct connections of inputs A–D to VCC or GND for function selection - its CMOS inputs draw ≤±0.1 μA leakage current, eliminating the need for external biasing resistors and reducing board area and BOM cost.

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 even if 5.5 V is applied to any pin - preventing damaging back-current flow between powered and unpowered sections of a system, such as in hot-swap or modular power architectures.

Can the 74LVC1G99GT,115 be used in a 5 V system with a 3.3 V supply?

Yes. With VCC = 3.3 V, the 74LVC1G99GT,115 accepts 5 V input signals safely (5 V tolerant), produces 3.3 V-compatible output levels, and maintains full functionality - enabling seamless bridging between legacy 5 V peripherals and modern low-voltage controllers without level translators.
