Nexperia USA Inc. 74LVC1G98GV,125

Overview

74LVC1G98GV,125 from Nexperia is a single-channel, 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, provides ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and enables voltage translation between 3.3 V and 5 V systems in space-constrained industrial control interfaces.

For engineers reviewing the 74LVC1G98GV,125 datasheet, 74LVC1G98GV,125 pinout, 74LVC1G98GV,125 application, or 74LVC1G98GV,125 equivalent, this device is selected for its reconfigurable logic capability in mixed-voltage PCBs, robust noise immunity in noisy environments, and compact SC-74 (SOT457) packaging for high-density routing on embedded sensor interface boards.

Technical Context

The 74LVC1G98GV,125 implements a programmable logic cell where three input pins (A, B, C) define function selection via truth table mapping - enabling dynamic logic assignment without hardware change. Its Schmitt-trigger inputs provide hysteresis (VH = 0.50 V min at VCC = 3.0 V), ensuring reliable signal conditioning for slow-rising or noisy control lines.

IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA, making it suitable for hot-swap and partial-power-down architectures. Propagation delay ranges from 0.5 ns (min) to 7.9 ns (max) at VCC = 3.0 V–3.6 V, with CPD = 20 pF confirming low dynamic power consumption in battery-sensitive applications.

FAQ

Can 74LVC1G98GV,125 operate with VCC = 1.8 V while accepting 5 V inputs?

Yes. The device supports 1.65 V to 5.5 V supply voltage and has 5 V tolerant inputs - meaning VI can safely reach 5.5 V even when VCC = 1.8 V. This enables direct interfacing with legacy 5 V sensors or microcontrollers without external level shifters, verified per JESD8-7 compliance and Table 7 operating conditions.

What logic function is implemented when A=H, B=L, C=H?

Per Table 4 (Function table), input combination A=H, B=L, C=H yields Y=H. Cross-referencing Table 5 (Function selection), this corresponds to the "2-input NAND" configuration (Fig. 3), where Y = NOT(A AND B) - with C acting as a don't-care in that specific mapping. The exact function depends on the chosen configuration mode, not just input state.

Does 74LVC1G98GV,125 support hot-swap in backplane applications?

Yes - its IOFF circuitry ensures outputs enter high-impedance state when VCC = 0 V, preventing damaging backflow current during insertion. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to pins, satisfying IEC 61000-4-2 Level 4 ESD immunity and enabling safe hot-plug operation in modular industrial backplanes.

How does the Schmitt-trigger input improve performance in noisy environments?

The Schmitt-trigger provides 0.50 V minimum hysteresis (VH) at VCC = 3.0 V, meaning VT+ = 1.50 V and VT− = 0.80 V. This 700 mV window rejects noise transients <700 mV amplitude, eliminating false triggering on slow-rising signals like mechanical switch closures or long PCB traces - confirmed by transfer characteristic curves in Figure 11 and Table 12.
