Nexperia USA Inc. 74LVC1G98GW,125

Overview

74LVC1G98GW,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, tolerates 5 V inputs/outputs, delivers ±24 mA drive at 3.0 V, and features IOFF for partial power-down protection. It is used in voltage-level translation and reconfigurable signal conditioning in space-constrained industrial control modules.

For engineers reviewing the 74LVC1G98GW,125 datasheet, 74LVC1G98GW,125 pinout, 74LVC1G98GW,125 application, or 74LVC1G98GW,125 equivalent, key selection criteria include its 6-pin TSSOP6 package, Schmitt-trigger noise immunity, 5 V tolerance in mixed-voltage systems, and IOFF-enabled safe power sequencing during system sleep states.

Technical Context

The device implements a programmable logic cell where three input pins (A, B, C) define function selection via truth table mapping, enabling dynamic reconfiguration without external components. Its Schmitt-trigger inputs provide hysteresis (e.g., 0.48 V typical at VCC = 1.8 V), ensuring robust noise rejection in noisy environments.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA max, making it suitable for hot-swap and partial-power-down architectures. Propagation delay ranges from 0.5 ns (VCC = 4.5–5.5 V) to 14.4 ns (VCC = 1.65–1.95 V), with guaranteed operation across –40 °C to +125 °C.

FAQ

Can 74LVC1G98GW,125 operate reliably at 1.65 V supply?

Yes. The device is fully specified from 1.65 V to 5.5 V, with propagation delay up to 14.4 ns and output drive ≥±4 mA at 1.65 V. Static characteristics including VIH/VIL thresholds and VOL/VOH levels are guaranteed across this range per Table 7 and Table 8 of the datasheet.

How does the IOFF feature behave when VCC is disconnected?

When VCC drops to 0 V, the IOFF circuit disables the output Y, limiting leakage current to ±2 μA maximum (Table 10). This prevents back-current flow from other powered devices on the same bus, protecting both the 74LVC1G98GW,125 and connected ICs during hot-swap or partial shutdown.

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

Per Table 4 (Function Table), A=H, B=L, C=L yields Y=H. Referring to Table 5 (Function Selection), this combination configures the device as a 2-input MUX with inverted output - where B selects between inverted A and C, producing Y = NOT((NOT A) AND B OR C AND (NOT B)).

Is the TSSOP6 package (SOT363-2) compatible with standard reflow profiles?

Yes. The SOT363-2 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. Its 1.25 mm body width and 0.65 mm pitch are supported by standard stencil apertures and placement accuracy requirements for Class II and III assembly lines.
