Nexperia USA Inc. 74LVC2G14GV-Q100H

Overview

74LVC2G14GV-Q100 from Nexperia is a dual inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V. It features 5 V-tolerant inputs, ±24 mA output drive at 3.0 V, and IOFF circuitry enabling partial power-down operation. It serves as a level translator and waveform shaper in mixed-voltage automotive sensor interfaces and timing circuits.

For engineers reviewing the 74LVC2G14GV-Q100 datasheet, 74LVC2G14GV-Q100 pinout, 74LVC2G14GV-Q100 application, or 74LVC2G14GV-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.40–1.40 V), propagation delay down to 2.7 ns at 5 V, IOFF-enabled bus isolation, and SC-74 (SOT457) package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent CMOS inverters with Schmitt-trigger input thresholds (VT+ and VT−), providing noise immunity and clean signal regeneration. Hysteresis voltage (VH) ranges from 0.40 V to 1.40 V depending on VCC, enabling reliable operation with slow-rising or noisy inputs such as mechanical switch signals or analog sensor outputs.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and supporting hot-swap and partial power-down architectures. Input tolerance up to 5.5 V allows direct interfacing with legacy 5 V logic while powered from 3.3 V or lower rails-critical for automotive body control modules integrating legacy and modern subsystems.

FAQ

What is the maximum input voltage the 74LVC2G14GV-Q100 can tolerate when VCC = 3.3 V?

The device accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions). This 5 V tolerance enables safe interfacing with legacy 5 V peripherals while operating from a 3.3 V supply-no external clamping or level-shifting circuitry is required.

Does the 74LVC2G14GV-Q100 support true bidirectional signal translation?

No-it is a unidirectional inverting buffer with Schmitt inputs. While it translates 5 V inputs to 3.3 V-compatible outputs, it cannot pass signals from output to input. Its IOFF feature only disables outputs during power-down; it does not enable reverse signal flow or bus arbitration functionality.

How does the IOFF function behave during power sequencing in a multi-rail system?

When VCC drops to 0 V, the IOFF circuit forces both outputs (1Y and 2Y) into high-impedance state, limiting leakage to ±2 μA maximum (Table 7). This prevents back-current from active 5 V buses into the unpowered device-ensuring safe power-up/down sequencing in gateways or domain controllers with independent 5 V and 3.3 V domains.

Can the 74LVC2G14GV-Q100 be used to build a stable relaxation oscillator?

Yes-its Schmitt-trigger inputs and rail-to-rail output swing make it ideal for RC-based relaxation oscillators, as demonstrated in Figure 10 of the datasheet. With typical hysteresis of 0.73 V at 3.0 V, it delivers predictable frequency stability across temperature and supply variations, supporting frequencies from ~1 kHz to 100 kHz using standard 1% resistors and capacitors.
