Nexperia USA Inc. 74LVC1G14GV-Q100,1

Overview

74LVC1G14GV-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 74LVC1G14GV-Q100 datasheet, 74LVC1G14GV-Q100 pinout, 74LVC1G14GV-Q100 application, or 74LVC1G14GV-Q100 equivalent, this page delivers verified functional role, Schmitt-trigger hysteresis values (e.g., VH = 0.64 V at VCC = 3.0 V), propagation delay (tpd = 3.0 ns typ at 3.3 V), IOFF leakage (<±2 μA), and automotive-grade thermal and ESD specifications - all confirmed from Nexperia's Rev. 9 product data sheet.

Technical Context

This device implements a single CMOS inverter with asymmetric Schmitt-trigger input thresholds (VT+ = 1.29 V, VT− = 0.88 V at VCC = 3.0 V), delivering 0.41 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 (up to 5.5 V) and complies with JEDEC standards JESD8-7 through JESD36 across 1.65–5.5 V supply ranges. Static and dynamic parameters are fully characterized over −40 °C to +125 °C, including guaranteed VOL ≤ 0.55 V at 24 mA sink and tpd ≤ 7.0 ns max at 3.3 V.

FAQ

Can 74LVC1G14GV-Q100 operate with a 1.65 V supply while driving a 5 V-tolerant load?

Yes - the device functions correctly at VCC = 1.65 V and its inputs tolerate up to 5.5 V regardless of supply voltage. However, the output swing is rail-to-rail (0 V to 1.65 V), so it cannot directly drive a 5 V logic input without an external pull-up or level shifter. The overvoltage tolerance applies only to inputs, not outputs.

What is the minimum recommended load capacitance for stable oscillator operation using this device?

Nexperia's relaxation oscillator reference design (Fig. 10) specifies CL ≥ 30 pF for reliable startup and frequency stability. Lower capacitances (e.g., <15 pF) may cause erratic oscillation or failure to start due to insufficient gate charging time relative to propagation delay and hysteresis thresholds.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes - the IOFF circuit engages when VCC falls below approximately 0.8 V, forcing outputs into high-impedance state. This behavior is intrinsic to the silicon design and requires no external enable signal or biasing; it is active across the full −40 °C to +125 °C range per characterization in Table 7.

How does the Schmitt-trigger hysteresis change with temperature at VCC = 3.3 V?

At VCC = 3.3 V, VH decreases from 0.64 V (typ) at 25 °C to 0.60 V (min) at +125 °C per Table 8. This 6% reduction maintains effective noise rejection across the full automotive temperature range, with VT+ and VT− tracking proportionally to preserve switching window integrity.
