Nexperia USA Inc. 74LV04ATPWJ

Overview

74LV04AT from Nexperia is a hex inverter IC with TTL-compatible inputs, Schmitt-trigger input thresholds, IOFF partial power-down capability, and operation across 4.5 V to 5.5 V supply. It provides six independent inverting logic gates in a TSSOP14 package, enabling level translation from 3.3 V to 5 V domains in mixed-voltage digital systems such as industrial control I/O modules.

For engineers reviewing the 74LV04AT datasheet, 74LV04AT pinout, 74LV04AT application, or 74LV04AT equivalent, this device is selected for robust noise immunity in slow-edge signal conditioning, low-power shutdown sequencing, and interface bridging between legacy TTL and modern 3.3 V logic subsystems.

Technical Context

The 74LV04AT implements six identical CMOS inverter stages, each featuring Schmitt-trigger inputs with hysteresis (VIH(AC) = 2 V, VIL(AC) = 0.8 V), ensuring reliable switching on noisy or slowly transitioning signals. Its IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ≤0.5 μA.

It operates over -40 °C to +125 °C with guaranteed propagation delay of ≤8.1 ns at 5 V/CL = 15 pF and supports dynamic mixed-mode voltage operation-inputs tolerate up to 5.5 V regardless of VCC state, enabling safe interfacing across voltage domains.

FAQ

Does the 74LV04AT support true 3.3 V to 5 V level translation?

Yes-it accepts 3.3 V logic-high inputs (VIH ≥2 V) while operating at VCC = 5 V, and its VOH ≥3.8 V at IO = −12 mA ensures compatible 5 V TTL output swing. Inputs tolerate up to 5.5 V regardless of VCC, enabling safe bidirectional interfacing without external components.

What is the purpose of the IOFF feature, and how does it behave during power-down?

IOFF disables all outputs when VCC = 0 V, placing them in high-impedance state to prevent back-current flow from live inputs or outputs into the unpowered IC. Measured IOFF leakage is ≤0.5 μA, protecting both the 74LV04AT and connected circuitry during hot-swap or partial power-down sequences.

Can the 74LV04AT drive a 50 pF capacitive load at full speed?

Yes-the datasheet specifies tpd ≤10.4 ns at VCC = 5 V and CL = 50 pF across −40 °C to +125 °C. This guarantees reliable 100 MHz toggle performance into typical PCB trace and input capacitance loads without waveform degradation or timing violation.

How does Schmitt-trigger input action improve noise immunity compared to standard CMOS inverters?

Schmitt-trigger inputs provide hysteresis: VIH(AC) = 2 V and VIL(AC) = 0.8 V yield a 1.2 V threshold gap. This prevents multiple transitions on slow-rising signals (e.g., mechanical switches, thermistor outputs) and rejects noise spikes ≤1.2 V peak-to-peak-eliminating need for external filtering.
