onsemi NC7SZ14L6X

Overview

NC7SZ14L6X from onsemi is a single-channel 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, and achieves 3.7 ns typical propagation delay into 50 pF at 5 V - enabling robust edge detection in sensor interfaces and clock clean-up circuits.

For engineers reviewing the NC7SZ14L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SIP6 MicroPak), confirmed Schmitt-trigger hysteresis (0.70–1.70 V), absolute max ratings (6.5 V input tolerance), power-down high-impedance behavior, and real-world use cases in industrial I/O conditioning and mixed-voltage logic interfacing.

Technical Context

The NC7SZ14L6X implements a CMOS-based Schmitt-trigger inverter with hysteresis defined by separate positive (V_P) and negative (V_N) thresholds - e.g., 2.90 V / 1.20 V at 5.5 V V_CC. Its input structure tolerates up to 5.5 V independent of V_CC, supporting 5 V-to-3.3 V level translation without external components.

It features power-down isolation: inputs and outputs enter high-impedance state when V_CC = 0 V, and exhibits ultra-low quiescent current (≤10 µA) over −40 °C to +85 °C. Propagation delay varies predictably with supply voltage and load - 6.5 ns max at 3.3 V/50 pF, 5.5 ns max at 5.0 V/50 pF - enabling timing-critical signal reshaping.

Key Specifications

Pinout & Package

SIP6 (MicroPak) package: 1.45 mm × 1.0 mm, 0.5 mm pitch, 6-pin leadless surface-mount with exposed thermal pad (Case 127EB). Pin 1 is marked via laser etch or microdot; no solderable leads - requires controlled reflow profile.

FAQ

What is the maximum input voltage rating for NC7SZ14L6X?

The NC7SZ14L6X supports DC input voltages up to 6.5 V absolute maximum, with functional 5.5 V tolerance independent of V_CC. This allows safe interfacing with 5 V peripherals even when powered from 1.8 V or 2.5 V rails - a key advantage over standard logic inverters. The NC7SZ14L6X maintains this rating across its full operating temperature range (−40 °C to +85 °C).

Does NC7SZ14L6X support power-down mode?

Yes, the NC7SZ14L6X enters a true high-impedance state when V_CC = 0 V: both inputs and outputs become Hi-Z, preventing back-current flow or unintended loading of upstream/downstream circuitry. This behavior is explicitly specified in the datasheet under "Power Down High Impedance Inputs / Outputs" and is verified across all operating temperatures - essential for hot-swap and partial-power-down architectures using the NC7SZ14L6X.

What is the hysteresis voltage of NC7SZ14L6X at 3.3 V V_CC?

At 3.3 V V_CC, the NC7SZ14L6X exhibits a typical hysteresis voltage (V_H) of 0.77 V, with a guaranteed minimum of 0.40 V and maximum of 1.20 V over temperature. This is derived from the difference between positive (V_P ≈ 2.20 V) and negative (V_N ≈ 1.43 V) thresholds. That hysteresis enables reliable switching on signals with >400 mV of superimposed noise - a core design value confirmed in the NC7SZ14L6X datasheet's DC Electrical Characteristics table.

Can NC7SZ14L6X drive a 50 pF capacitive load at 10 MHz?

Yes, the NC7SZ14L6X is characterized for 50 pF loads with RL = 500 Ω, delivering 6.5 ns max propagation delay at 5.0 V and 7.5 ns max at 3.3 V over temperature. At 10 MHz (100 ns period), the total delay represents <8% of the cycle - well within timing margins for signal reshaping. The NC7SZ14L6X also specifies CPD = 30 pF at 5 V, confirming its suitability for dynamic loading in clock and data path applications.

Is NC7SZ14L6X pin-compatible with other TinyLogic inverters in SIP6?

No - the NC7SZ14L6X uses a unique 6-pin SIP6 (MicroPak) pinout (NC/A/GND/Y/NC/V_CC) that differs from other TinyLogic SIP6 devices like NC7SZ04L6X (inverter without Schmitt trigger) or NC7SZ17L6X (buffer). Pin 1 and Pin 5 are NC on NC7SZ14L6X but assigned to functional signals in those variants. PCB layout must be specific to the NC7SZ14L6X pin map; no drop-in replacement exists within the SIP6 footprint.
