Nexperia USA Inc. 74AHC1G14GV-Q100,1

Overview

74AHC1G14GV-Q100 from Nexperia is a single-channel automotive-grade Schmitt-trigger inverter with CMOS input thresholds, 2.0 V to 5.5 V supply range, overvoltage-tolerant inputs (up to 5.5 V), and operation from −40 °C to +125 °C. It functions as a noise-immune signal conditioner in mixed-voltage sensor interfaces and timing circuits.

For engineers reviewing the 74AHC1G14GV-Q100 datasheet, 74AHC1G14GV-Q100 pinout, 74AHC1G14GV-Q100 application, or 74AHC1G14GV-Q100 equivalent, key selection criteria include hysteresis voltage (0.45–1.6 V), propagation delay (1.0–16.5 ns), input threshold symmetry, AEC-Q100 Grade 1 qualification, and SC-74A (SOT753) package compatibility with high-density PCB layouts.

Technical Context

This device implements a single inverting Schmitt trigger with defined positive-going (VT+) and negative-going (VT−) input thresholds-e.g., VT+ = 3.85 V and VT− = 1.65 V at VCC = 5.5 V-enabling robust waveform shaping in noisy environments. Its CMOS input structure ensures low static current (≤40 μA at VCC = 5.5 V) and rail-to-rail output swing.

The logic function is strictly inverting: low input yields high output, high input yields low output. Input hysteresis (VH = VT+ − VT−) ranges from 0.45 V to 1.6 V depending on supply voltage, directly enabling stable oscillation in relaxation oscillator topologies without external feedback components.

FAQ

What is the maximum recommended operating frequency for 74AHC1G14GV-Q100?

The device does not specify a maximum clock frequency, but its propagation delay (1.0–16.5 ns) and hysteresis behavior make it suitable for edge-detection and waveform shaping up to approximately 50 MHz in typical 15 pF load conditions. For sustained oscillation, relaxation oscillator frequency depends on external R and C values and is limited by tpd and input transition rate-not by an intrinsic clock limit.

Can 74AHC1G14GV-Q100 interface between 3.3 V and 5 V logic domains?

Yes. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC setting, and its CMOS thresholds scale with supply voltage. With VCC = 3.3 V, it reliably interprets 5 V inputs as HIGH and outputs 3.3 V logic levels-enabling bidirectional level translation without external resistors or dedicated translators.

Is pin 1 of the SOT753 package internally connected?

No. Pin 1 is explicitly designated as "n.c." (not connected) in the official pin description table. It has no internal bond wire or silicon connection and must remain unconnected in the PCB layout-neither tied to GND nor VCC-to avoid unintended parasitic coupling or mechanical stress on the die attach.

How does temperature affect hysteresis voltage (VH)?

VH decreases slightly with rising temperature: at VCC = 5.5 V, VH is 0.45–1.6 V over −40 °C to +125 °C. The minimum value (0.45 V) occurs at +125 °C, ensuring usable noise margin even at peak junction temperature. This monotonic reduction is characterized and guaranteed-not extrapolated-and remains sufficient for automotive signal integrity requirements.
