onsemi NC7SZ04L6X

Overview

NC7SZ04L6X from ON Semiconductor is a single ultra-high-speed CMOS inverter in a 6-lead MicroPak™ package, operating from 1.65V to 5.5V V_CC, delivering 2.4ns typical propagation delay into 50pF at 5V and ±24mA output drive at 3V - used for level translation, signal inversion, and noise-immune logic buffering in space-constrained portable and industrial control systems.

For engineers reviewing the NC7SZ04L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, validated pin functions, confirmed DC/AC electrical specs across voltage/temperature ranges, and two rigorously cross-referenced alternative parts with documented functional and application-level differences.

Technical Context

The NC7SZ04L6X implements a single unbuffered inverter gate using advanced CMOS process technology, supporting rail-to-rail input tolerance up to 6V independent of V_CC, enabling robust 5V-to-3V translation without external resistors. Its inputs and outputs enter high-impedance state when V_CC = 0V, supporting live-insertion and power-down isolation.

Proprietary noise/EMI reduction circuitry minimizes switching transients, while its ultra-low quiescent ICC (2.0µA typical) and dynamic CPD (20pF at 3.3V) ensure minimal power impact in battery-powered applications. Input hysteresis is not implemented - it is a standard CMOS inverter with defined VIH/VIL thresholds per supply voltage.

Key Specifications

Pinout & Package

NC7SZ04L6X is housed in a 6-lead MicroPak™ package (JEDEC MO-252 variation UAAD), 1.00mm wide, 0.35mm pitch, with exposed die pad for thermal enhancement and no internal thermal slug connection. Pin 1 is identified by extended mark length per JEDEC spec.

FAQ

What is the maximum input voltage rating for NC7SZ04L6X, and does it depend on V_CC?

The NC7SZ04L6X supports DC input voltages from –0.5V to +6.0V regardless of V_CC level - confirmed in Absolute Maximum Ratings. This over-voltage tolerance enables direct interfacing with 5V signals even when V_CC is 1.8V or 2.5V, eliminating external level shifters. The NC7SZ04L6X datasheet explicitly states "Inputs tolerate voltages up to 6V, independent of V_CC operating voltage."

Does NC7SZ04L6X have built-in hysteresis or Schmitt-trigger input behavior?

No, the NC7SZ04L6X is a standard CMOS inverter without hysteresis. Its input threshold is approximately V_CC/2, with VIH and VIL specified as 0.7×V_CC and 0.3×V_CC respectively at V_CC ≥ 2.3V. It is not suitable for noisy signal conditioning unless external RC filtering or a dedicated Schmitt trigger (e.g., NC7SZ14) is used. The NC7SZ04L6X Function Table and DC Electrical Characteristics confirm standard inverter transfer characteristics.

Can NC7SZ04L6X be used with V_CC = 0V, and what happens to its I/O pins?

Yes - when V_CC = 0V, both inputs and outputs of the NC7SZ04L6X enter a high-impedance state, as stated in the Description section: "The inputs and output are high-impedance when V_CC is 0V." This feature supports hot-swap and partial power-down scenarios. However, inputs must still remain within –0.5V to 6.0V to avoid damage, per Absolute Maximum Ratings. This behavior is intrinsic to the NC7SZ04L6X's internal power-gating architecture.

What is the thermal resistance (θ_JA) of the NC7SZ04L6X MicroPak™ package, and how does it affect power dissipation?

The NC7SZ04L6X MicroPak™ package has θ_JA = 500°C/W, per the Thermal Resistance table. At +85°C ambient, its maximum allowed power dissipation is 130mW - meaning junction temperature rise is limited to 65°C above ambient under worst-case static conditions. For dynamic operation, CPD = 20pF at 3.3V determines frequency-dependent ICCD, so actual thermal load depends on toggle rate. This θ_JA value assumes standard JEDEC 2S2P test board; real-world PCB layout will alter effective thermal performance.

Are pins 1 and 5 of NC7SZ04L6X electrically connected or internally tied?

Pins 1 and 5 of the NC7SZ04L6X are designated "NC" (No Connect) in the Pin Definitions table and are not internally bonded - they serve only as mechanical alignment aids and must remain unconnected in the PCB layout. The NC7SZ04L6X datasheet explicitly lists them as "No Connect" with no circuit role, and Figure 9 shows no internal bond wires to these pads. Connecting them risks unintended parasitic coupling or mechanical stress on the die attach.
