onsemi NC7SZ04FHX-L22175

Overview

NC7SZ04FHX-L22175 from onsemi is a single ultra-high-speed CMOS inverter in the TinyLogic UHS family, designed for level translation and signal inversion in low-voltage digital logic paths. It operates across 1.65 V to 5.5 V V_CC, delivers ±24 mA output drive at 3 V, achieves 2.4 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 bridging in portable and mixed-supply systems.

For engineers reviewing the NC7SZ04FHX-L22175 datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6 (1.0 × 1.0 mm) MicroPak2 package, power-down high-impedance I/O behavior, input leakage ≤±1 µA, and guaranteed operation from −40 °C to +85 °C - all critical for space-constrained, battery-powered, and industrial control designs.

Technical Context

The NC7SZ04FHX-L22175 implements a single unbuffered inverter gate using advanced CMOS process technology optimized for speed-power trade-off. Its input structure supports voltage-level independence: inputs tolerate up to 5.5 V regardless of V_CC, allowing safe interfacing between higher- and lower-voltage domains without external resistors or translators.

When V_CC = 0 V, both input and output terminals enter high-impedance state, preventing back-driving and enabling hot-swap or power-gating use cases. Propagation delay varies with supply voltage and load - e.g., 2.1 ns (typ) at 3.3 V/50 pF and 2.4 ns (typ) at 5.0 V/50 pF - reflecting its UHS architecture's voltage-dependent timing performance.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage rating for NC7SZ04FHX-L22175?

The NC7SZ04FHX-L22175 supports DC input voltages up to 5.5 V regardless of V_CC level - a key feature enabling safe interfacing between higher-voltage peripherals and lower-voltage logic domains without external protection components. This over-voltage tolerance is explicitly specified in the Absolute Maximum Ratings table and confirmed across all operating conditions in the datasheet.

Does NC7SZ04FHX-L22175 support power-down mode?

Yes, the NC7SZ04FHX-L22175 enters a true high-impedance state on both input and output terminals when V_CC = 0 V. This behavior is documented in the Description section and verified in the Pin Definitions and Functional Operation sections - ensuring no back-current flow during partial power-down sequences in multi-rail systems.

What is the typical propagation delay of NC7SZ04FHX-L22175 at 3.3 V?

The NC7SZ04FHX-L22175 exhibits a typical propagation delay of 2.1 ns into a 50 pF load at 3.3 V V_CC, as measured under AC Electrical Characteristics conditions. This value is confirmed in Table 3 (AC Electrical Characteristics) and reflects its Ultra-High Speed design targeting sub-5 ns timing in real-world 3.3 V logic environments.

Which package type does NC7SZ04FHX-L22175 use?

The NC7SZ04FHX-L22175 uses the UDFN6 (1.0 mm × 1.0 mm, 0.35 mm pitch) MicroPak2 package, identified in the Ordering Information table and Package Dimensions section. This 6-pin variant differs from the 5-pin SOT-23/SC-74A/SC-88A versions and provides the smallest footprint in the NC7SZ04 family for ultra-dense PCB layouts.

Is NC7SZ04FHX-L22175 RoHS compliant and lead-free?

Yes, the NC7SZ04FHX-L22175 is Pb-free, halogen-free/BFR-free, and fully RoHS compliant, as stated in the Features section and confirmed in the Ordering Information table. Its marking "CC" and packaging code "FHX" align with onsemi's MicroPak2 RoHS-compliant product line, meeting JEDEC J-STD-020 MSL1 requirements.
