Product details

Overview

NC7SZ125L6X-L22175 from onsemi is a single ultra-high-speed CMOS buffer with three-state output, designed for level translation and bus isolation in space-constrained digital systems. It operates across 1.65 V to 5.5 V V_CC, delivers ±24 mA output drive at 3 V, and achieves 2.6 ns typical propagation delay into 50 pF at 5 V - enabling high-speed signal routing in portable and low-power embedded interfaces.

For engineers reviewing the NC7SZ125L6X-L22175 datasheet, pinout, applications, or equivalent options, key selection criteria include its MicroPak-6 package footprint, over-voltage tolerant inputs (up to 5.5 V independent of V_CC), 3-state enable timing (t_PZL/t_PHZ ≤ 6.0 ns at 3.3 V), and compatibility with 1.8 V/2.5 V/3.3 V/5 V logic domains.

Technical Context

The NC7SZ125L6X-L22175 implements a non-inverting buffer with active-low three-state enable (OE), where output Y follows input A when OE is low and enters high-impedance state when OE is high. Its advanced CMOS process enables rail-to-rail input tolerance and output clamping above V_CC in 3-state mode - critical for mixed-voltage bus interfacing.

It supports dynamic operation from −40 °C to +85 °C with guaranteed DC parameters including VIH = 0.70×V_CC, VIL = 0.30×V_CC, VOH ≥ 2.30 V (at V_CC = 3.0 V, I_OH = −24 mA), and VOL ≤ 0.55 V (at V_CC = 3.0 V, I_OL = 24 mA), ensuring robust noise margins across its full supply range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - supports direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters.
t_PD (Typ)	2.6 ns at 5 V into 50 pF - enables >300 MHz signal routing in compact PCB layouts.
Output Drive	±24 mA at 3 V V_CC - drives multiple LVTTL/LVCMOS loads or short traces without external buffering.
Input Tolerance	Inputs tolerate up to 5.5 V regardless of V_CC - allows safe 5 V-to-3 V translation with no external components.
3-State Leakage	I_OZ ≤ ±10 µA at V_CC = 0–5.5 V - minimizes bus contention current during power-down or idle states.
Power Dissipation	CPD = 17 pF at 3.3 V - determines dynamic ICCD = CPD × V_CC × f_IN, enabling accurate power budgeting at high frequencies.

Pinout & Package

NC7SZ125L6X-L22175 is packaged in MicroPak-6 (UDFN6, 1.0 mm × 1.0 mm, 0.35 mm pitch), a leadless, bottom-terminated, space-saving package requiring solder paste stencil optimization and X-ray inspection for assembly verification.

Pin/Terminal	Circuit Role	Design Meaning
1 (OE)	Active-low three-state enable input	Drives output Y to high-impedance when logic HIGH; must be pulled LOW (e.g., via MCU GPIO) to enable buffer function.
2 (A)	Non-inverting data input	Accepts 0–5.5 V signals regardless of V_CC; compatible with legacy 5 V peripherals driving modern low-voltage logic.
3 (GND)	Ground reference	Primary return path for all I/O and supply currents; requires low-inductance connection to system ground plane.
4 (Y)	Three-state buffered output	Provides rail-to-rail swing (0 to V_CC) when enabled; floats to high-Z when OE = HIGH, isolating downstream loads.
5 (NC)	No-connect terminal	Internally unconnected; must remain unpopulated or left floating - no external connection permitted.
6 (V_CC)	Positive supply voltage	Supplies core logic and output drivers; requires local 100 nF ceramic decoupling placed within 2 mm of this pin.

Key Features

Feature	Design Value
Ultra-High Speed	2.6 ns t_PD (typ) at 5 V enables sub-5 ns edge-to-edge timing in high-frequency control loops and clock distribution paths.
Over-Voltage Tolerant Inputs	5.5 V-tolerant A and OE pins eliminate external resistive dividers when interfacing 5 V sensors or legacy controllers to 3.3 V/1.8 V SoCs.
Power-Down High-Z	Inputs and outputs enter high-impedance state when V_CC = 0 V - prevents back-driving and latch-up during hot-plug or partial power-down sequences.
MicroPak-6 Footprint	1.0 mm × 1.0 mm body with 0.35 mm pitch reduces board area by >70% vs. SC-74A, supporting ultra-dense wearables and IoT modules.
EMI Reduction Circuitry	Proprietary slew-rate control lowers radiated emissions without compromising propagation delay - simplifies EMC pre-compliance testing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer-with-three-state-output applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G125DBVR	SC-70-5 package (2.0 mm × 1.25 mm); t_PD = 3.7 ns (typ) at 3.3 V; VIH/VIL referenced to V_CC only (no 5.5 V tolerance)	Lacks over-voltage input tolerance - requires external protection when interfacing 5 V sources.	Preferred for cost-sensitive, single-voltage (3.3 V) designs where board area is less constrained than with MicroPak-6.
74LVC1G125GW,125	SC-88A (2.1 mm × 1.25 mm); t_PD = 3.2 ns (typ) at 3.3 V; same 5.5 V input tolerance but lower drive (±20 mA at 3 V)	Compatible pinout with NC7SZ125P5X; slightly larger footprint than MicroPak-6 but more widely available in distribution.	Recommended when MicroPak assembly capability is unavailable or when higher-volume tape-and-reel availability is required.

Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the NC7SZ125L6X-L22175 offers the smallest footprint (1.0 mm²), fastest propagation (2.6 ns), and highest output drive (±24 mA), making it optimal for ultra-compact, high-performance mixed-voltage signal routing where PCB real estate and timing margin are critical.

FAQ

What is the maximum operating temperature range for NC7SZ125L6X-L22175?

The NC7SZ125L6X-L22175 is specified for continuous operation from −40 °C to +85 °C ambient temperature. This range is validated across all electrical parameters including propagation delay, output drive, and input/output voltage thresholds, ensuring reliable performance in industrial and automotive under-hood environments where thermal cycling occurs.

Does NC7SZ125L6X-L22175 support 5 V logic inputs when powered from 1.8 V V_CC?

Yes, the NC7SZ125L6X-L22175 inputs (A and OE) tolerate voltages up to 5.5 V regardless of V_CC level. When V_CC = 1.8 V, a 5 V input signal is safely accepted without damage or logic misinterpretation - enabling direct 5 V-to-1.8 V level translation without external components.

What is the purpose of the NC (No Connect) pin on NC7SZ125L6X-L22175?

Pin 5 on the NC7SZ125L6X-L22175 is an internally unconnected terminal. It must not be soldered to any trace or plane. Leaving it unconnected ensures proper internal biasing and prevents unintended current paths that could degrade ESD performance or cause functional failure in the MicroPak-6 package.

How does the 3-state disable timing of NC7SZ125L6X-L22175 compare to competing buffers?

The NC7SZ125L6X-L22175 achieves t_PLZ/t_PHZ ≤ 6.0 ns (max) at 3.3 V V_CC with 50 pF load - faster than SN74LVC1G125DBVR (7.5 ns) and comparable to 74LVC1G125GW,125 (6.2 ns). This rapid disable response minimizes bus contention windows in multi-master digital systems.

Is NC7SZ125L6X-L22175 RoHS compliant and halogen-free?

Yes, the NC7SZ125L6X-L22175 is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. This compliance is confirmed in the official onsemi datasheet revision 7 (August 2024) and verified through material declarations provided by onsemi's authorized distribution channels.
