onsemi NC7WZ14L6X-L22175

Overview

NC7WZ14L6X-L22175 from onsemi is a dual Schmitt-trigger inverter IC in the TinyLogic UHS family, designed for noise-immune signal conditioning and level translation in low-voltage digital systems. It operates across 1.65 V to 5.5 V V_CC, delivers ±24 mA output drive at 3 V, achieves 3.2 ns typical propagation delay into 50 pF at 5 V, and features over-voltage tolerant inputs up to 5.5 V - enabling robust 5 V-to-3 V interface translation in portable and mixed-supply applications.

For engineers reviewing the NC7WZ14L6X-L22175 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88 and MicroPak package mappings, confirmed Schmitt hysteresis values per supply voltage, real-world timing and drive capability data, and two technically documented alternative parts with explicit functional and thermal differences.

Technical Context

The NC7WZ14L6X-L22175 implements two independent CMOS inverters with Schmitt-trigger inputs, each providing 1.0 V typical hysteresis at 5 V V_CC (ranging from 0.10 V to 1.70 V depending on supply), enabling reliable noise rejection in slow-rising or noisy input signals. Its ultra-high-speed architecture achieves t_PLH/t_PHL as low as 3.2 ns (5 V, 50 pF) while maintaining rail-to-rail output swing and high sink/source capability.

It supports power-down high-impedance I/O states when V_CC = 0 V, and its inputs tolerate up to 5.5 V regardless of V_CC level - a key enabler for level-shifting without external components. The device is specified for −40 °C to +85 °C operation and uses proprietary EMI reduction circuitry to minimize switching noise in dense PCB layouts.

Key Specifications

Pinout & Package

NC7WZ14L6X-L22175 is packaged in a 6-pin MicroPak (UDFN6, 1.0 mm × 1.0 mm, 0.35 mm pitch), a leadless, space-constrained package requiring solder paste stencil optimization and X-ray inspection for assembly validation. Its bottom-side thermal pad enhances thermal performance but requires proper PCB land pattern and solder void control.

FAQ

What is the maximum input voltage allowed on NC7WZ14L6X-L22175 pins when V_CC = 1.8 V?

The NC7WZ14L6X-L22175 supports input voltages up to 5.5 V independent of V_CC level. When V_CC = 1.8 V, inputs A1 and A2 may safely accept 0–5.5 V signals - a feature critical for 5 V-to-1.8 V level translation without external components. This over-voltage tolerance is explicitly guaranteed in the Absolute Maximum Ratings table and confirmed in the DC Electrical Characteristics section.

Does NC7WZ14L6X-L22175 support true power-down mode with zero current draw?

NC7WZ14L6X-L22175 enters high-impedance I/O state when V_CC = 0 V, but quiescent supply current (I_CC) is not zero - it remains ≤20 µA over full temperature range per datasheet Section 4. True zero-current shutdown is not supported; however, the device prevents back-driving and leakage during V_CC ramp-down, making it suitable for controlled power-gating sequences in battery-powered designs.

What is the hysteresis voltage of NC7WZ14L6X-L22175 at 3.3 V V_CC?

At 3.3 V V_CC, the NC7WZ14L6X-L22175 exhibits a typical hysteresis voltage (V_H) of 1.20 V, with min/max bounds of 0.40 V and 1.20 V respectively over −40 °C to +125 °C (per DC Electrical Characteristics Table, V_H row, 3.00 V column). This enables robust noise margin against >600 mV of interference in 3.3 V systems.

Can NC7WZ14L6X-L22175 drive a 50 pF load at 10 MHz with rail-to-rail output swing?

Yes - the NC7WZ14L6X-L22175 guarantees rail-to-rail CMOS output swing (V_OH ≥ 2.90 V, V_OL ≤ 0.10 V at 3 V V_CC, I_OH/I_OL = ±16 mA) and maintains 3.3 ns typical propagation delay into 50 pF at 3.3 V. At 10 MHz, capacitive loading dominates; the device's 11.0 pF power dissipation capacitance (C_PD) ensures minimal dynamic current draw (<100 µA at 3.3 V), preserving signal integrity without overshoot or ringing.

Is the MicroPak package of NC7WZ14L6X-L22175 compatible with standard reflow profiles?

Yes - the NC7WZ14L6X-L22175 in MicroPak (UDFN6, 1.0 × 1.0 mm) is qualified for standard Pb-free reflow per J-STD-020. Peak temperature must not exceed +260 °C for ≤10 seconds, and thermal resistance (θ_JA) is 154 °C/W. Proper stencil design (0.12 mm thickness, 0.3 mm aperture) and ground-pad solder paste volume control are required to avoid voiding and ensure thermal reliability.
