Product details

Overview

NC7NZ34L8X-L22185 from onsemi is a triple non-inverting buffer IC in the TinyLogic UHS family, fabricated in advanced CMOS for ultra-high-speed operation with high drive strength and low static power. It operates across 1.65 V to 5.5 V V_CC, delivers ±24 mA output drive at 3 V, and features overvoltage-tolerant inputs (up to 5.5 V) enabling 5 V-to-3 V level translation in mixed-voltage logic systems.

For engineers reviewing the NC7NZ34L8X-L22185 datasheet, pinout, applications, or equivalent options, key selection considerations include propagation delay (2.4 ns typ at 5 V into 50 pF), MicroPak-8 package footprint (1.6 × 1.6 mm, 0.5 mm pitch), input/output high-impedance during power-down, and compatibility with broad V_CC ranges and mixed-supply interfaces.

Technical Context

The NC7NZ34L8X-L22185 implements three independent non-inverting buffer stages in a single 8-pin UQFN package. Each buffer supports rail-to-rail input voltage tolerance (0–5.5 V) independent of V_CC, and exhibits matched t_PLH/t_PHL propagation delays down to 2.4 ns (5 V, 50 pF load).

It integrates proprietary noise/EMI reduction circuitry and features power-down high-impedance I/O states when V_CC = 0 V. The device is specified for −40 °C to +85 °C operation and supports dynamic current consumption modeling via CPD (9–11 pF at 3.3–5.0 V).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters
t_PD (Typ)	2.4 ns at 5 V into 50 pF - supports >200 MHz signal buffering in high-speed digital control paths
Output Drive	±24 mA at 3 V - drives multiple standard CMOS loads or short PCB traces without external buffers
Input Voltage Tolerance	0 V to 5.5 V independent of V_CC - allows safe 5 V input signaling even when powered from 1.8 V
I_OFF (Max)	10 µA at V_CC = 0 V - ensures true high-impedance isolation during system power sequencing
Package	MicroPak-8 (UQFN8, 1.6 × 1.6 mm, 0.5 mm pitch) - provides minimal board area and low parasitic inductance

Pinout & Package

NC7NZ34L8X-L22185 is housed in an 8-pin MicroPak (UQFN8) package per JEDEC MO-255 variation UAAD, with exposed thermal pad and 0.5 mm pitch. Pin 1 is located at the lower-left corner when top marking "P9" is read left-to-right.

Pin/Terminal	Circuit Role	Design Meaning
1	A1 (Input)	First buffer input - accepts overvoltage-tolerant logic signals up to 5.5 V
2	Y1 (Output)	Non-inverting output of first buffer - drives downstream CMOS loads with ±24 mA capability
3	A2 (Input)	Second buffer input - electrically isolated from A1; shares same V_CC/GND supply domain
4	GND	Ground reference - must be connected to system ground plane for stable noise performance
5	Y2 (Output)	Non-inverting output of second buffer - matches Y1 timing and drive characteristics
6	A3 (Input)	Third buffer input - fully independent; supports asynchronous signal routing
7	Y3 (Output)	Non-inverting output of third buffer - enables compact fan-out of critical control signals
8	V_CC	Supply voltage - powers all three buffers; decoupling capacitor (0.1 µF) required near pin

Key Features

Feature	Design Value
Ultra-High-Speed Propagation	2.4 ns typical delay at 5 V enables precise timing alignment in clock distribution and data path conditioning
Overvoltage-Tolerant Inputs	Accepts 5.5 V inputs regardless of V_CC setting - eliminates need for external level translators in mixed-voltage FPGA/CPU I/O banks
Power-Down High-Z I/O	Inputs and outputs enter high-impedance state when V_CC = 0 V - prevents back-driving during hot-swap or partial-power-down sequences
Low Dynamic Power Consumption	CPD = 9–11 pF - minimizes switching current (I_CCD) in high-frequency applications, reducing heat and supply ripple
Pb-Free, Halogen-Free Construction	RoHS-compliant MicroPak-8 package - meets IPC/JEDEC J-STD-020B reflow requirements and environmental compliance mandates

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G34DCUR	3.3 V only V_CC range (1.65–3.6 V); no 5.5 V input tolerance; 32 mA drive at 3.3 V	Limited to single-supply 3.3 V systems; unsuitable for 5 V-to-3 V translation	Prefer when operating exclusively at 3.3 V and higher drive is needed
74LVC3G17GW,125	Schmitt-trigger inputs (hysteresis ~0.3 V); same V_CC range; 24 mA drive at 3.3 V	Better noise immunity on slow or noisy inputs; not suitable for clean, fast digital signals requiring minimal delay variation	Prefer for debouncing mechanical switches or interfacing with slow-rising sensor outputs

Compared with SN74LVC3G34DCUR and 74LVC3G17GW,125, the NC7NZ34L8X-L22185 uniquely supports full 1.65–5.5 V operation with 5.5 V input tolerance - making it the only option among the three capable of seamless 5 V-to-3 V translation without external components.

FAQ

What is the maximum input voltage rating for NC7NZ34L8X-L22185?

The NC7NZ34L8X-L22185 supports DC input voltages from −0.5 V to 6.5 V absolute maximum, and functional overvoltage tolerance up to 5.5 V independent of V_CC. This allows safe interfacing with 5 V signals even when powered from 1.8 V or 2.5 V rails - a key feature confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official datasheet.

Does NC7NZ34L8X-L22185 support power-down mode with high-impedance I/O?

Yes, the NC7NZ34L8X-L22185 places both inputs and outputs into high-impedance states when V_CC = 0 V, as explicitly stated in the Description and verified in the DC Electrical Characteristics table under I_OFF (power-off leakage current). This behavior enables safe hot-insertion and partial power-down scenarios without risk of back-driving.

What is the typical propagation delay of NC7NZ34L8X-L22185 at 3.3 V?

The NC7NZ34L8X-L22185 achieves a typical propagation delay of 2.3 ns at 3.3 V into a 50 pF load, per the AC Electrical Characteristics table. This value is measured under t_PLH/t_PHL conditions with CL = 50 pF and RL = 500 Ω, confirming its suitability for sub-5 ns timing-critical paths in modern digital systems.

Is NC7NZ34L8X-L22185 pin-compatible with other TinyLogic triple buffers?

No - the NC7NZ34L8X-L22185 uses the 8-pin MicroPak (UQFN8) package with specific pinout (1:A1, 2:Y1, 3:A2, 4:GND, 5:Y2, 6:A3, 7:Y3, 8:V_CC). It is not pin-compatible with US8-packaged variants like NC7NZ34K8X, which use different pin assignments and land patterns despite identical logic function.

What is the thermal resistance (θ_JA) of NC7NZ34L8X-L22185 in its MicroPak-8 package?

The NC7NZ34L8X-L22185 has a junction-to-ambient thermal resistance (θ_JA) of 232 °C/W in the MicroPak-8 package, as specified in the Recommended Operating Conditions table. This value assumes standard JEDEC test board conditions and informs thermal design for continuous operation at rated load across the full −40 °C to +85 °C temperature range.
