NXP Semiconductors 74LVC04AD,112

Overview

74LVC04AD from Nexperia is a hex inverter logic IC with Schmitt-trigger inputs, operating across 1.2 V to 3.6 V supply, tolerant to 5.5 V inputs, and rated for -40 °C to +125 °C. It provides six independent inverting buffers with propagation delay as low as 2.0 ns (VCC = 3.0–3.6 V), 24 mA output drive, and supports level translation between 3.3 V and 5 V systems in industrial control and mixed-voltage I/O interfacing.

For engineers reviewing the 74LVC04AD datasheet, 74LVC04AD pinout, 74LVC04AD application, or 74LVC04AD equivalent, key selection criteria include input overvoltage tolerance, wide VCC range compatibility, Schmitt-trigger noise immunity, and SO14 package thermal derating behavior above 100 °C.

Technical Context

This device implements six independent CMOS inverters with Schmitt-trigger input thresholds-enabling robust operation with slow-rising or noisy signals. Each gate exhibits hysteresis of ~0.3 V at VCC = 3.3 V, improving noise margin over standard CMOS inputs.

It complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2–3.6 V VCC range and supports direct TTL-level interfacing without external pull-ups or level shifters.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage the 74LVC04AD can tolerate?

The 74LVC04AD accepts input voltages up to 5.5 V regardless of VCC level-verified per Absolute Maximum Ratings table. This overvoltage tolerance enables direct connection to 5 V logic without external clamping or level-shifting circuitry, provided input current remains within ±50 mA limits.

Does the 74LVC04AD require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs should be tied HIGH or LOW using direct connections to VCC or GND. Schmitt-trigger inputs prevent floating-state oscillation, and internal input leakage is ≤±0.1 μA at VCC = 3.6 V-making external resistors unnecessary for stability or power savings.

Can the 74LVC04AD drive a 50 pF load at 10 MHz with VCC = 3.3 V?

Yes. At VCC = 3.3 V and CL = 50 pF, typical propagation delay is 2.0 ns and output skew is ≤1.0 ns. Dynamic power dissipation is calculated as PD = CPD × VCC² × fi × N = 9.9 pF × (3.3 V)² × 10 MHz × 1 ≈ 1.1 mW-well within the 500 mW total package limit at 25 °C ambient.

Is the SO14 package of the 74LVC04AD RoHS compliant and lead-free?

Yes. The 74LVC04AD in SO14 (SOT108-1) packaging meets RoHS Directive 2011/65/EU and is fully lead-free, with matte tin (Sn) lead finish and halogen-free molding compound-verified in Nexperia's material declarations and certified by third-party lab analysis.
