Nexperia USA Inc. 74LVCU04APW,112

Overview

74LVCU04APW,112 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 I²C bus level shifting and clock signal conditioning.

For engineers reviewing the 74LVCU04APW,112 datasheet, 74LVCU04APW,112 pinout, 74LVCU04APW,112 application, or 74LVCU04APW,112 equivalent, key selection criteria include supply voltage range, output drive strength, propagation delay consistency across channels, and input threshold compatibility with 1.8 V/3.3 V mixed-signal systems.

Technical Context

This device implements six independent unbuffered CMOS inverters in a single monolithic silicon die. Each inverter features symmetrical input thresholds (V_IH ≈ 0.7×V_CC, V_IL ≈ 0.3×V_CC) and rail-to-rail output swing, enabling bidirectional voltage translation without external biasing.

The unbuffered architecture eliminates internal staging, resulting in minimal phase shift between input and output - critical for clock inversion and waveform shaping in timing-sensitive paths like oscillator feedback loops and reset signal generation.

FAQ

What is the maximum operating frequency for reliable inversion using 74LVCU04APW,112?

The device does not specify a maximum clock frequency, but its 3.7 ns typical propagation delay at 3.3 V and 50 pF load supports reliable operation up to approximately 100 MHz in non-critical timing paths. For oscillator feedback or clock distribution, ensure total path delay (including trace and load) remains below half the target period to avoid duty cycle distortion.

Can 74LVCU04APW,112 drive a 50 Ω transmission line directly?

Yes - with ±24 mA output drive at 3.3 V, it can source/sink sufficient current to drive a 50 Ω line terminated at the far end, achieving ~3.3 V swing. However, series termination (e.g., 33 Ω resistor at driver output) is recommended to suppress reflections and maintain signal integrity on PCB traces longer than 2 cm.

Is 74LVCU04APW,112 suitable for use with 1.2 V logic inputs?

No - its minimum specified supply voltage is 1.65 V, and input thresholds scale with V_CC. At 1.65 V, V_IL is ~0.5 V and V_IH is ~1.16 V; a 1.2 V logic high falls below V_IH, risking unreliable switching. Use only with 1.8 V or higher logic families.

Does this device require external pull-up resistors on unused inputs?

Yes - unused CMOS inputs must be tied to V_CC or GND to prevent floating states that cause increased supply current, noise susceptibility, and potential latch-up. Do not leave inputs unconnected; a 10 kΩ pull-up or pull-down resistor is sufficient for static biasing.
