Nexperia USA Inc. 74HC2G14GV-Q100H

Overview

74HC2G14GV-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 2.0–6.0 V supply range and CMOS-level inputs. It features two independent Schmitt-trigger inverters with hysteresis (e.g., 1.40 V typical at VCC = 4.5 V), enabling clean signal regeneration in noisy environments such as engine control sensor interfaces.

For engineers reviewing the 74HC2G14GV-Q100 datasheet, 74HC2G14GV-Q100 pinout, 74HC2G14GV-Q100 application, or 74HC2G14GV-Q100 equivalent, this device supports robust waveform shaping, astable/monostable multivibrator design, and noise-immune digital conditioning in automotive powertrain and body electronics where input rise/fall times are uncontrolled.

Technical Context

This IC implements two independent CMOS-based Schmitt-trigger inverters with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Each channel transforms slow-varying analog-like inputs into sharp, jitter-free digital outputs using defined VT+ (e.g., 2.60 V typ. at VCC = 4.5 V) and VT− (e.g., 1.47 V typ.) thresholds.

It delivers balanced propagation delays (16 ns typ. at VCC = 4.5 V, CL = 50 pF) and low dynamic power dissipation (CPD = 10 pF), with static supply current under 1.0 μA at VCC = 6.0 V and ambient 25 °C - optimized for low-power automotive subsystems requiring stable timing integrity across wide temperature ranges.

Key Specifications

Pinout & Package

74HC2G14GV-Q100 uses the SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.95 mm height, lead pitch 0.95 mm. Pin 1 is marked by an index notch below the 'H14' top-side marking.

FAQ

Can 74HC2G14GV-Q100 operate reliably at 2.0 V supply in automotive applications?

Yes. The device is fully specified down to 2.0 V supply across −40 °C to +125 °C, with guaranteed VOH ≥ 1.9 V and VOL ≤ 0.1 V at IO = ±4.0 mA. Its Schmitt trigger thresholds scale proportionally with VCC, maintaining consistent hysteresis (e.g., VH ≈ 0.6 × VCC), ensuring robust noise rejection even at minimum rail.

What is the maximum recommended capacitive load for stable 74HC2G14GV-Q100 operation?

The datasheet specifies dynamic characteristics up to 50 pF load capacitance. For reliable operation beyond this, derate output drive strength: at CL = 100 pF, propagation delay increases to ~38 ns (max) at VCC = 4.5 V, and transition time extends to ~22 ns (max). Keep trace lengths short and avoid stubs to prevent ringing.

How does the input clamp diode affect interfacing with 12 V sensor signals?

The integrated clamp diodes allow safe connection to voltages up to VCC + 0.5 V. To interface with 12 V sensors, use a series current-limiting resistor (e.g., 10 kΩ) to restrict IIK to <20 mA, enabling direct coupling without external protection - verified per JESD78 latch-up immunity >100 mA.

Is 74HC2G14GV-Q100 pin-compatible with non-automotive versions like 74HC2G14GV?

Yes - identical SC-74 (SOT457) package, pinout, and electrical behavior. However, the -Q100 suffix denotes full AEC-Q100 qualification (including extended temperature testing, failure analysis, and lot traceability), whereas standard versions lack automotive process controls and documentation - not acceptable for production automotive use.
