onsemi NC7SZ10L6X

Overview

NC7SZ10L6X from onsemi is a single 3-input NAND gate in the TinyLogic UHS family, designed for high-speed logic level translation and signal conditioning in space-constrained digital systems. It operates across 1.65 V to 5.5 V V_CC, delivers 2.4 ns typical propagation delay at 5 V into 50 pF, supports ±24 mA output drive at 3 V, and features overvoltage-tolerant inputs up to 5.5 V - enabling robust 5 V-to-3 V interface applications.

For engineers reviewing the NC7SZ10L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak-6), confirmed logic function (Y = A·B·C), validated AC/DC electrical specs, and real-world use context for low-voltage portable, industrial control, and mixed-supply interface designs.

Technical Context

The NC7SZ10L6X implements a CMOS-based 3-input NAND gate with patented noise/EMI reduction circuitry and power-down high-impedance I/O states when V_CC = 0 V. Its input structure tolerates 5.5 V regardless of V_CC, supporting level-shifting without external components.

It is characterized across −40 °C to +85 °C and specified for 1.65–5.5 V operation, with propagation delays as low as 2.0 ns (typ) at 5 V/50 pF and input capacitance of 4 pF - confirming suitability for high-frequency clock gating and fast data path control.

FAQ

What is the maximum input voltage rating for NC7SZ10L6X, and does it depend on V_CC?

The NC7SZ10L6X supports DC input voltages up to 5.5 V on pins A, B, and C - independent of the applied V_CC value. This overvoltage tolerance is explicitly guaranteed in the Absolute Maximum Ratings table and enables safe interfacing with 5 V signals even when V_CC is 1.8 V or 2.5 V. The NC7SZ10L6X datasheet confirms this behavior applies across the full −40 °C to +85 °C temperature range.

Does NC7SZ10L6X have a defined power-down state, and how does it behave when V_CC = 0 V?

Yes, the NC7SZ10L6X enters a true high-impedance state on both inputs and output when V_CC = 0 V. This is documented in the Description section and verified in the Absolute Maximum Ratings table, where input/output pins tolerate −0.5 V to 6.5 V regardless of supply condition. This feature prevents back-driving and leakage currents during hot-swap or partial-power-down scenarios - a key reliability advantage in modular systems using NC7SZ10L6X.

What is the typical propagation delay of NC7SZ10L6X under standard test conditions, and at which V_CC is it lowest?

The NC7SZ10L6X achieves its lowest typical propagation delay of 2.0 ns at V_CC = 5.0 V ± 0.5 V with C_L = 50 pF and R_L = 500 Ω, as specified in the AC Electrical Characteristics table. At 3.3 V, t_PD (typ) is 2.4 ns under identical loading - confirming consistent high-speed performance across its full 1.65–5.5 V operating range. These values are measured per Figure 5 and Figure 7 test configurations in the NC7SZ10L6X datasheet.

Can NC7SZ10L6X drive standard TTL loads, and what output current capability supports this?

Yes, the NC7SZ10L6X can directly drive standard TTL loads due to its ±24 mA output drive capability at V_CC = 3.0 V, as specified in the DC Electrical Characteristics table. This exceeds the ±0.4 mA requirement of standard TTL inputs and supports fanout of up to 60 LS-TTL loads or 10+ Schottky TTL loads. The NC7SZ10L6X maintains rail-to-rail VOH/VOL levels across its operating range, ensuring reliable logic-level compatibility.

Is NC7SZ10L6X compatible with lead-free reflow soldering processes, and what is its peak temperature rating?

Yes, NC7SZ10L6X is Pb-free, halogen-free, and RoHS-compliant, qualified for standard lead-free reflow profiles. Its junction lead temperature rating is +260 °C for 10 seconds - matching IPC/JEDEC J-STD-020 requirements for SnAgCu (SAC305) soldering. The MicroPak-6 package's thermal resistance (θ_JA = 154 °C/W) and exposed paddle design support efficient heat dissipation during reflow and operation - critical for high-density NC7SZ10L6X deployments.
