Product details

Overview

NLV74VHCT14DR2G from onsemi is a hex Schmitt-trigger inverter IC designed for noise-immune signal conditioning in automotive and industrial control logic paths, featuring 2.0 V to 5.5 V supply operation, <10 ns propagation delay at 5 V, and ±8 mA output drive capability. It interfaces between noisy sensors and microcontroller inputs in engine control units and body electronics modules.

For engineers reviewing the NLV74VHCT14DR2G datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger hysteresis (typically 0.9 V at V_CC = 5 V), AEC-Q100 Grade 1 qualification, and SOIC-14 package compatibility with legacy VHCT logic footprints.

Technical Context

This device implements six independent Schmitt-trigger inverters in a single monolithic CMOS structure, using onsemi's proprietary VHCT (Very High Speed CMOS TTL-compatible) process. Each gate provides hysteresis to reject input noise up to ±400 mV and ensures clean digital transitions even with slow-rising or distorted waveforms.

The NLV74VHCT14DR2G operates across the full automotive temperature range (−40 °C to +125 °C) and meets AEC-Q100 stress test requirements for humidity, thermal cycling, and ESD (±2 kV HBM). Its input thresholds scale linearly with V_CC, enabling robust interfacing across 3.3 V and 5 V mixed-voltage systems.

Hysteresis Voltage (ΔV_IN)	0.9 V typical at V_CC = 5 V - rejects contact bounce and EMI-induced glitches on switch inputs
Output Drive (I_OH/I_OL)	−8 mA / +8 mA at V_CC = 5 V - directly drives LED indicators or small-signal MOSFET gates
Input Thresholds (V_IT+/V_IT−)	1.8 V / 0.9 V at V_CC = 5 V - ensures reliable switching with TTL-level signals

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC74VHC14DT	Same VHCT family but not AEC-Q100 qualified; wider V_CC range (2.0–5.5 V) and identical pinout	Suitable for industrial controls but not certified for automotive under-hood deployment	Select MC74VHC14DT only for non-automotive designs where AEC-Q100 is not mandated
SN74LVC14APWR	Lower V_CC min (1.65 V), higher max drive (±24 mA), but no AEC-Q100 qualification and narrower temp range (−40 °C to +85 °C)	Applicable in portable consumer devices but lacks extended temperature reliability for engine bay use	Choose SN74LVC14APWR when 1.8 V system compatibility or higher drive strength is prioritized over automotive qualification

The NLV74VHCT14DR2G is rated for continuous operation from −40 °C to +125 °C and is AEC-Q100 Grade 1 qualified. This specification ensures reliable performance in under-hood automotive environments where ambient temperatures exceed 105 °C. The NLV74VHCT14DR2G maintains specified propagation delay and output drive within this full range without derating.

Does NLV74VHCT14DR2G support 3.3 V logic systems?

Yes, NLV74VHCT14DR2G operates over 2.0 V to 5.5 V, making it fully compatible with 3.3 V systems. Its TTL-compatible input thresholds (V_IT+ ≈ 2.0 V, V_IT− ≈ 1.0 V at V_CC = 3.3 V) ensure reliable recognition of standard 3.3 V logic levels. The NLV74VHCT14DR2G also provides clean output transitions with hysteresis to prevent chatter on marginal inputs.

Is NLV74VHCT14DR2G pin-compatible with standard 74LS14?

Yes, NLV74VHCT14DR2G uses the same SOIC-14 pinout as industry-standard 74LS14 and 74HC14 devices. All six inverter inputs and outputs map identically, allowing drop-in replacement in existing PCB layouts. The NLV74VHCT14DR2G retains identical terminal numbering and functional assignment, simplifying migration from legacy bipolar or CMOS logic.

What is the typical hysteresis voltage of NLV74VHCT14DR2G at 5 V supply?

The typical hysteresis voltage (ΔV_IN) for NLV74VHCT14DR2G is 0.9 V at V_CC = 5 V, with a minimum of 0.5 V guaranteed across temperature and voltage. This hysteresis enables robust rejection of noise spikes up to ±400 mV on input lines. The NLV74VHCT14DR2G maintains consistent hysteresis behavior across its full operating range, supporting reliable switch debouncing and sensor signal cleanup.

Can NLV74VHCT14DR2G drive LEDs directly?

Yes, NLV74VHCT14DR2G can directly drive standard indicator LEDs with series resistors. Its ±8 mA output drive at 5 V allows sinking or sourcing sufficient current for low-power LEDs (e.g., 2 mA at 2.0 V forward voltage). When used in this role, the NLV74VHCT14DR2G eliminates need for external transistor buffers while maintaining logic-level compatibility and fast edge rates.
