onsemi NLVHC1G14DFT1G

Overview

NLVHC1G14DFT1G from onsemi is a single high-speed CMOS Schmitt-trigger inverter in SC-88A (SOT-353) package, operating from 2.0 V to 6.0 V, with 7 ns typical propagation delay at 5 V, ±2 mA output drive, and hysteresis voltage of 0.40 V (typ) at 4.5 V - used for noise-immune signal conditioning in sensor interface and power-on reset circuits.

For engineers reviewing the NLVHC1G14DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger input thresholds (VT+ = 3.15 V, VT− = 1.35 V at VCC = 4.5 V), rail-to-rail output swing, low ICC (≤1 µA max at 25 °C), and −55 °C to +125 °C operating range for automotive and industrial environments.

Technical Context

The NLVHC1G14DFT1G implements a single-stage inverting buffer with Schmitt-trigger input logic, enabling clean digital signal regeneration from slow or noisy analog inputs. Its internal design provides symmetrical tPLH/tPHL delays and matched IOH/IOL output impedance, ensuring consistent edge timing across supply voltages.

It operates within a wide VCC range (2.0–6.0 V) and supports full-rail input/output voltage levels, with hysteresis (VH = 0.40 V typ at 4.5 V) preventing chatter during slow transitions. The device is fabricated using silicon gate CMOS technology and contains fewer than 100 FETs.

FAQ

What is the function of Pin 2 (N/C) on the NLVHC1G14DFT1G?

Pin 2 on the NLVHC1G14DFT1G is internally unconnected (N/C) and serves no electrical function. It must be left floating or tied to GND - never driven or used as a signal node. This pin exists solely for mechanical symmetry in the SC-88A package and has no impact on NLVHC1G14DFT1G logic operation or timing performance.

Does the NLVHC1G14DFT1G support 2.0 V logic operation?

Yes, the NLVHC1G14DFT1G is fully specified down to 2.0 V VCC per its Recommended Operating Conditions table. At 2.0 V, it maintains valid Schmitt-trigger thresholds (VT+ ≈ 1.0 V, VT− ≈ 0.5 V), 100 ns max propagation delay, and rail-to-rail output swing - making NLVHC1G14DFT1G suitable for battery-powered 2.0 V systems such as coin-cell IoT sensors.

How does the hysteresis of the NLVHC1G14DFT1G improve noise immunity?

The NLVHC1G14DFT1G provides programmable hysteresis via separate VT+ (3.15 V) and VT− (1.35 V) thresholds at 4.5 V VCC, yielding 1.8 V differential. This prevents output oscillation when input signals cross the logic threshold slowly or with superimposed noise - a key advantage over standard inverters in NLVHC1G14DFT1G-based sensor debouncing and power-supply monitoring circuits.

Can the NLVHC1G14DFT1G drive a 50 pF capacitive load reliably?

Yes - the NLVHC1G14DFT1G is characterized up to 50 pF at VCC = 2.0 V (tPLH/tPHL ≤ 100 ns), and its ±2 mA output drive ensures stable edge rates into 50 pF loads. For best results, keep trace lengths short and place a 0.1 µF ceramic decoupling capacitor near the NLVHC1G14DFT1G VCC pin to maintain supply stability during capacitive switching.

Is the NLVHC1G14DFT1G pin-compatible with other SC-88A logic devices?

No - while the NLVHC1G14DFT1G uses the SC-88A package, its pinout (GND–N/C–A–VCC–Y) is specific to single-gate Schmitt inverters and differs from other SC-88A logic functions (e.g., AND, OR, NAND). Always verify pin assignment against the official NLVHC1G14DFT1G datasheet - do not assume mechanical compatibility implies functional or pinout compatibility.
