onsemi NLV74LVX14DTR2G

Overview

NLV74LVX14DTR2G from onsemi is a hex Schmitt-trigger inverter IC designed for noise-immune signal conditioning in mixed-voltage digital systems. It features 5 V-tolerant inputs (up to 6.5 V), 3.3 V nominal supply operation, 6.8 ns typical propagation delay at V_CC = 3.3 V, ±25 mA output drive, and hysteresis of 0.3–1.2 V - enabling reliable reception of slow-rising signals in industrial control interfaces.

For engineers reviewing the NLV74LVX14DTR2G datasheet, pinout, applications, or equivalent options, this device serves as a drop-in upgrade for legacy LVX04 logic where input noise immunity, level translation between 3 V and 5 V domains, or waveform squaring of degraded clock/data lines is required.

Technical Context

The NLV74LVX14DTR2G implements six independent Schmitt-trigger inverters in a single TSSOP-14 package, each with asymmetric input thresholds (V_T+ = 2.20 V, V_T− = 0.90 V at V_CC = 3.0 V) to deliver 1.3 V nominal hysteresis. Its 5 V-tolerant inputs operate up to 6.5 V regardless of V_CC, allowing direct interfacing with 5 V microcontrollers or sensors while powered from a 3.3 V rail.

It supports full industrial temperature range (−40 °C to +85 °C), exhibits balanced t_PLH/t_PHL delays (≤16.0 ns max at V_CC = 3.3 V, C_L = 50 pF), and maintains low dynamic noise (V_OLP ≤ 0.5 V) - making it suitable for use in noisy factory-floor I/O conditioning and automotive body-control modules.

FAQ

What is the maximum input voltage rating for NLV74LVX14DTR2G?

The NLV74LVX14DTR2G supports DC input voltages from −0.5 V to +6.5 V, independent of V_CC. This 5 V-tolerant capability allows direct connection to 5 V logic families or sensors without external protection circuitry, even when powered from a 3.3 V supply. The absolute maximum rating is strictly enforced per onsemi's design and testing - exceeding +6.5 V risks permanent damage.

Does NLV74LVX14DTR2G support operation at 2.5 V supply?

Yes, NLV74LVX14DTR2G is fully specified for V_CC = 2.0 V to 3.6 V, including 2.5 V operation. At 2.5 V, propagation delay increases to ≤19.5 ns (max), output drive reduces to ±16 mA, and hysteresis narrows to ~0.25–0.95 V - all within guaranteed limits per the datasheet's Recommended Operating Conditions table. System validation at 2.5 V is recommended for marginal timing paths.

Is NLV74LVX14DTR2G pin-compatible with standard 74LVX04 inverters?

Yes, NLV74LVX14DTR2G is pin- and function-compatible with MC74LVX04, sharing identical TSSOP-14 pinout and supply requirements. However, NLV74LVX14DTR2G adds Schmitt-trigger inputs with hysteresis, whereas LVX04 uses standard CMOS inputs. Substituting NLV74LVX14DTR2G for LVX04 improves noise immunity but may alter timing behavior on fast edges due to input threshold differences.

What is the thermal performance of NLV74LVX14DTR2G in TSSOP-14 package?

In TSSOP-14 (Case 948G), NLV74LVX14DTR2G has a junction-to-ambient thermal resistance (θ_JA) of 145 °C/W (typical, JEDEC-standard board). At maximum rated power dissipation (833 mW), junction temperature rise is ~121 °C above ambient - well within safe operating limits only with adequate copper pour and airflow. For continuous 85 °C ambient operation, derate power to ≤350 mW using thermal vias and 1-in² 2-oz copper pad.

Can NLV74LVX14DTR2G drive a 50 pF capacitive load at 10 MHz?

Yes, NLV74LVX14DTR2G is characterized for C_L = 50 pF loads with t_PD ≤ 16.0 ns (max) at V_CC = 3.3 V. At 10 MHz (100 ns period), the worst-case delay consumes only 16% of the cycle - leaving ample margin for setup/hold timing. Total dynamic power at this condition is ~1.8 mW per inverter (calculated via CPD = 21 pF), confirming suitability for high-frequency signal conditioning.
