onsemi NC7SV04L6X

Overview

NC7SV04L6X from onsemi is a single ultra-low-power (ULP-A) inverter logic gate designed for voltage-level translation and signal inversion in space-constrained, low-voltage systems. It operates across 0.9 V to 3.6 V supply range, delivers 1.5 ns propagation delay at 3.3 V (typ), supports ±24 mA I_O drive, and features IOFF partial power-down protection. It is used in portable sensor interfaces and battery-powered microcontroller I/O conditioning.

For engineers reviewing the NC7SV04L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak UDFN6), confirmed V_CC/GND/A/Y terminal roles, functional truth table compliance, overvoltage-tolerant inputs up to 3.6 V, and real-world timing behavior under 15 pF load conditions.

Technical Context

The NC7SV04L6X implements a CMOS-based inverter with rail-to-rail input voltage tolerance (−0.5 V to V_CC + 0.5 V) and active-mode output swing within 0.1–0.2 V of rails. Its IOFF circuitry disables both PMOS and NMOS paths when V_CC = 0 V, preventing back-drive current leakage between powered and unpowered system domains.

Propagation delay varies with supply voltage and load: 1.5 ns (typ) at V_CC = 3.3 V with R_L = 500 Ω and C_L = 30 pF; 2.8 ns (max) under same conditions across −40 °C to +85 °C. Input capacitance is 2.0 pF, and power-dissipation capacitance is 10.0 pF - enabling accurate dynamic power estimation via P_D = C_PDV_CC²f.

FAQ

What is the minimum operating voltage for NC7SV04L6X?

The NC7SV04L6X is fully specified to operate down to 0.9 V V_CC, with functional performance validated across −40 °C to +85 °C. At 0.9 V, propagation delay increases to 17.4 ns (typ) under light load, and output drive drops to ±100 µA - sufficient for high-impedance logic inputs but not for driving capacitive loads or LEDs. This makes NC7SV04L6X suitable for ultra-low-power always-on monitoring circuits where supply voltage may dip near battery cutoff.

Does NC7SV04L6X support level shifting between different voltage domains?

Yes, NC7SV04L6X supports bidirectional level shifting in inverter configuration due to its overvoltage-tolerant inputs (up to 3.6 V) and rail-swing outputs. For example, with V_CC = 1.8 V, it accepts 3.3 V input signals on Pin 2 (A), and produces a 0–1.8 V inverted output on Pin 4 (Y). This eliminates external level translators in mixed-voltage I/O paths such as connecting a 3.3 V sensor to a 1.8 V microcontroller - a key use case confirmed in onsemi's application guidance for the TinyLogic ULP-A series.

What is the purpose of the NC pins on NC7SV04L6X?

NC7SV04L6X has two No Connect (NC) pins - Pin 1 and Pin 6 - which are physically present in the UDFN6 package but internally unconnected to any die circuitry. These pins serve mechanical anchoring and thermal dissipation roles; they may be left floating or tied to GND for improved solder joint reliability. Neither pin carries electrical function, and routing traces or applying voltage to them violates the device's absolute maximum ratings and may compromise long-term reliability.

How does IOFF protection work in NC7SV04L6X during system power-down?

IOFF protection in NC7SV04L6X disables both pull-up and pull-down transistors when V_CC = 0 V, effectively isolating the input (A) and output (Y) terminals. Measured IOFF leakage is ≤0.5 µA across −40 °C to +85 °C, preventing unwanted current flow from powered downstream logic into the unpowered NC7SV04L6X. This behavior is explicitly tested and guaranteed per JEDEC JESD78 Class II latch-up standards - critical for maintaining signal integrity in multi-rail systems undergoing staggered power sequencing.

Is NC7SV04L6X pin-compatible with other TinyLogic inverters in UDFN6?

No - NC7SV04L6X is not pin-compatible with other TinyLogic inverters in UDFN6, such as NC7SZ04L6X or NC7WZ04L6X. While all share the same physical UDFN6 outline, their pin assignments differ: NC7SV04L6X places V_CC on Pin 5 and GND on Pin 3, whereas NC7SZ04L6X swaps these (V_CC on Pin 3, GND on Pin 5). Using them interchangeably causes immediate functional failure or damage. Always verify pinout diagrams in the respective datasheets - NC7SV04L6X pin mapping is unique to the ULP-A series.
