Nexperia USA Inc. 74LVC1G98GV-Q100H

Overview

74LVC1G98GV-Q100 from Nexperia is an automotive-grade, low-power configurable logic gate with Schmitt-trigger inputs, supporting MUX, AND, OR, NAND, NOR, inverter, and buffer functions via 3-bit configuration (A/B/C inputs). It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, and features IOFF for partial power-down protection. Used in automotive body control modules for signal conditioning between mixed-voltage sensor interfaces.

For engineers reviewing the 74LVC1G98GV-Q100 datasheet, 74LVC1G98GV-Q100 pinout, 74LVC1G98GV-Q100 application, or 74LVC1G98GV-Q100 equivalent, this device serves as a voltage-tolerant, function-reconfigurable logic element in space-constrained automotive PCBs requiring AEC-Q100 Grade 1 compliance and robust noise immunity.

Technical Context

This device implements a single configurable logic cell using CMOS technology with Schmitt-trigger inputs enabling reliable operation in noisy automotive environments. Its 3-input configuration logic (A/B/C) selects one of eight standard logic functions without external programming circuitry - all determined by static input states tied to VCC or GND.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while 5 V-tolerant I/O allows direct interfacing with legacy 5 V microcontrollers and sensors. Propagation delay ranges from 0.5 ns (VCC = 4.5–5.5 V) to 14.4 ns (VCC = 1.65–1.95 V), with hysteresis (VH) up to 1.40 V at 5.5 V for enhanced noise rejection.

FAQ

Can 74LVC1G98GV-Q100 be used as a standalone level shifter between 3.3 V and 5 V logic domains?

Yes - its 5 V-tolerant inputs and CMOS output structure allow it to translate 3.3 V logic levels to 5 V-compatible outputs without external components. When configured as a buffer with VCC = 3.3 V, it accepts 0–5 V inputs and drives 0–3.3 V outputs; with VCC = 5 V, it drives 0–5 V outputs while accepting 3.3 V inputs directly. No pull-up resistors or additional gates are required.

What happens to the Y output when VCC is disconnected or ramping during power sequencing?

The IOFF circuit activates automatically when VCC drops below ~0.8 V, placing the Y output in a high-impedance state with leakage ≤±2 μA. This prevents back-driving of upstream devices or loading of powered-down sections - critical for safe power sequencing in multi-rail automotive ECUs where subsystems power up/down asynchronously.

How is logic function selection implemented without programming pins or serial interface?

Function selection is purely static and determined by the DC voltage states of the three inputs A, B, and C. Each combination of HIGH/LOW on these pins maps to a specific logic function (e.g., A=L,B=L,C=L → Y=HIGH = inverter mode). No clock, enable, or configuration register is involved - the device behaves as combinational logic with Schmitt-trigger inputs, eliminating firmware dependencies.

Does the Schmitt-trigger input affect propagation delay specifications?

Yes - the hysteresis (VT+ and VT−) introduces a controlled delay variation of ≤0.3 ns compared to non-Schmitt inputs, but this is fully characterized in the datasheet's tpd tables. The benefit - immunity to slow-rising or noisy edges - outweighs the minor delay impact, especially in automotive harness applications where edge rate degradation is common.
