Nexperia USA Inc. 74LVC1G14GW-Q100,1

Overview

74LVC1G14GW-Q100 from Nexperia is a single-channel Schmitt-trigger inverter 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, ±24 mA output drive at 3.0 V, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V logic domains in body control modules and sensor interface circuits.

For engineers reviewing the 74LVC1G14GW-Q100 datasheet, 74LVC1G14GW-Q100 pinout, 74LVC1G14GW-Q100 application, or 74LVC1G14GW-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (min 0.25 V at 3.0 V), overvoltage-tolerant inputs (to 5.5 V), automotive temperature rating, TSSOP5 package compatibility, and IOFF-enabled system-level power sequencing.

Technical Context

This device implements a single CMOS inverter with asymmetric Schmitt-trigger input thresholds-VT+ = 1.26–1.71 V and VT− = 0.88–1.27 V at VCC = 3.0 V-providing 0.25–0.64 V hysteresis to reject noise on slow-rising signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It supports mixed-voltage interfacing via overvoltage-tolerant inputs (rated to 5.5 V independent of VCC) and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range. Propagation delay is 0.7–7.0 ns depending on VCC and load conditions.

FAQ

Can the 74LVC1G14GW-Q100 operate with a 1.65 V supply and still drive a 5 V-tolerant input?

Yes - the device operates down to 1.65 V supply and features overvoltage-tolerant inputs rated to 5.5 V. Its outputs swing rail-to-rail (0 V to VCC), so at 1.65 V supply it delivers 0–1.65 V logic levels. The 5 V tolerance applies only to inputs, not outputs; connecting its output directly to a 5 V input requires an external level shifter or pull-up configuration.

What is the minimum recommended decoupling capacitance for stable operation?

A minimum 100 nF X7R ceramic capacitor placed within 2 mm of the VCC and GND pins is required. For high-noise environments or fast-switching loads, add a parallel 10 nF capacitor. Layout must minimize loop inductance - avoid vias in decoupling paths and use solid ground plane beneath the package.

Does the IOFF feature work when VCC is ramping during power-up or power-down?

Yes - the IOFF circuit activates when VCC falls below approximately 0.8 V and remains active until VCC rises above ~1.2 V. During this transition window, outputs are held in high-impedance state, preventing contention or back-current flow even during non-monotonic power sequencing common in multi-rail automotive systems.

How does hysteresis vary with supply voltage, and why does it matter in automotive applications?

Hysteresis increases with VCC: 0.25 V at 3.0 V, 0.34 V at 4.5 V, and 0.41 V at 5.5 V. This scaling ensures consistent noise rejection across battery voltage fluctuations (9–16 V system), especially critical for signals routed near alternators or ignition systems where conducted EMI peaks exceed 1 Vpp.
