Nexperia USA Inc. 74LVCU04APW/S400,1

Overview

74LVCU04APW/S400,1 from NXP Semiconductors is a hex unbuffered inverter IC in TSSOP-14 package, operating from 1.65 V to 3.6 V supply, with ±24 mA output drive, 3.7 ns typical propagation delay at 3.3 V, and CMOS input compatibility. It serves as a signal-level logic inverter in low-voltage digital interface circuits such as level-shifting buffers and clock conditioning paths.

For engineers reviewing the 74LVCU04APW/S400,1 datasheet, 74LVCU04APW/S400,1 pinout, 74LVCU04APW/S400,1 application, or 74LVCU04APW/S400,1 equivalent, key selection criteria include supply voltage range, output drive strength, propagation delay consistency across rail, input hysteresis absence, and TSSOP-14 thermal performance in dense PCB layouts.

Technical Context

This device implements six independent unbuffered CMOS inverters on a single die, with no internal feedback or Schmitt-trigger hysteresis-enabling precise waveform inversion without threshold shifting. Each inverter exhibits rail-to-rail output swing and symmetrical rise/fall times under matched load conditions.

Designed for 1.8 V and 3.3 V logic domains, it supports mixed-voltage interfacing when used with appropriate series termination. Its unbuffered architecture minimizes propagation delay variation versus buffered counterparts but requires careful layout to avoid oscillation on unterminated lines.

FAQ

Is 74LVCU04APW/S400,1 compatible with 1.8 V I/O standards?

Yes. With guaranteed operation down to 1.65 V V_CC, it fully complies with 1.8 V LVCMOS I/O standards-including input thresholds (V_IL ≤ 0.63 V, V_IH ≥ 1.17 V at V_CC = 1.8 V) and output swing (V_OL ≤ 0.36 V, V_OH ≥ 1.44 V). No level-shifting circuitry is needed.

Can this device drive a 50 Ω transmission line directly?

Yes, under controlled conditions. Its ±24 mA output drive supports 50 Ω loads with proper series termination (e.g., 33 Ω resistor at source) to limit overshoot and maintain signal integrity up to ~100 MHz. Layout must minimize stub length and ensure solid return path.

Does 74LVCU04APW/S400,1 include Schmitt-trigger inputs?

No. It features standard CMOS inputs without hysteresis. This enables precise edge alignment in clock/data paths but requires clean, monotonic input transitions. For noisy environments, external RC filtering or a Schmitt-trigger variant (e.g., 74LVC14) should be considered.

What is the maximum operating ambient temperature for continuous use?

The device is rated for operation from −40 °C to +125 °C ambient temperature per its industrial-grade qualification. Thermal derating is not required below 125 °C when mounted on a standard FR-4 PCB with ≥1 cm² copper pour beneath the exposed pad (if present) and ≤20 °C/W board-level thermal resistance.
