Product details

Overview

NC7WZ32L8X-L22185 from onsemi is a dual 2-input OR gate in the TinyLogic UHS family, fabricated using advanced CMOS technology for ultra-high-speed logic operation with high drive strength and low static power. It operates across 1.65 V to 5.5 V V_CC, supports 5 V-to-3 V level translation via overvoltage-tolerant inputs (up to 6.5 V), and delivers 2.4 ns typical propagation delay into 50 pF at 5 V - used in compact battery-powered interface logic and voltage-level bridging circuits.

For engineers reviewing the NC7WZ32L8X-L22185 datasheet, pinout, applications, or equivalent options, key selection criteria include its MicroPak-8 package footprint, ±24 mA output drive at 3 V, power-down high-impedance I/O behavior, and compatibility with mixed-voltage system interconnects requiring fast, low-power discrete logic.

Technical Context

The NC7WZ32L8X-L22185 implements two independent OR gates with fully buffered inputs and outputs, supporting rail-to-rail logic swing and operating down to 1.65 V while maintaining sub-4 ns propagation delay at 3.3 V. Its input structure enables 6.5 V tolerance regardless of V_CC, allowing safe interfacing between 5 V legacy peripherals and 3.3 V or 1.8 V microcontrollers.

It features proprietary noise/EMI reduction circuitry and exhibits power-off high-impedance I/O states when V_CC = 0 V, eliminating bus contention during power sequencing. The device's quiescent ICC remains ≤10 µA across the full temperature range (−40 °C to +85 °C) and supply range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters
t_PD (Typ)	2.4 ns into 50 pF at 5 V - supports >200 MHz toggle rates in critical timing paths
I_OH/I_OL	±24 mA at 3 V - drives multiple LVTTL or CMOS loads directly without buffers
Input Voltage Tolerance	Up to 6.5 V independent of V_CC - allows robust 5 V-to-3 V signal translation without external clamping
Power-Down State	High-impedance I/O at V_CC = 0 V - prevents back-driving and leakage during hot-swap or partial power-down
Operating Temperature	−40 °C to +85 °C - qualified for industrial ambient environments without derating

Pinout & Package

NC7WZ32L8X-L22185 is packaged in an 8-pin MicroPak (UQFN8, 1.6 mm × 1.6 mm, 0.5 mm pitch, case 523AY), a leadless, space-saving surface-mount package with exposed thermal pad and bottom-side I/O terminals.

Pin/Terminal	Circuit Role	Design Meaning
1	Y1	Output of first OR gate - routed to downstream logic or enable path with 24 mA sink/source capability
2	B2	Second input of second OR gate - accepts overvoltage-tolerant signals up to 6.5 V
3	A2	First input of second OR gate - electrically identical to B2; both inputs support full V_CC-independent voltage tolerance
4	GND	Ground reference - connected to PCB thermal pad for enhanced thermal dissipation and noise immunity
5	V_CC	Positive supply - decoupling capacitor must be placed within 2 mm for stable high-speed operation
6	Y2	Output of second OR gate - independently driven; no internal coupling to Y1
7	B1	Second input of first OR gate - shares same electrical specs as A1, A2, B2
8	A1	First input of first OR gate - all four inputs are identical, fully buffered, and ESD-protected

Key Features

Feature	Design Value
Ultra-High-Speed Propagation	2.4 ns t_PD (5 V, 50 pF) enables use in 200+ MHz clock-domain boundary logic and fast interrupt combiners
Overvoltage-Tolerant Inputs	6.5 V absolute max input rating independent of V_CC eliminates need for external resistors or translators in mixed-voltage IO domains
Power-Down High-Z I/O	Inputs and outputs enter high-impedance state at V_CC = 0 V - prevents backfeed and ensures clean power sequencing in multi-rail systems
Low Dynamic Power	CPD = 18 pF at 5 V - minimizes switching current in high-frequency toggling applications, reducing system-level power budget impact

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G32DBVR	SO-8 package (3.0 mm × 1.25 mm); t_PD = 3.7 ns (3.3 V, 50 pF); 5 V tolerant inputs only up to V_CC + 0.5 V	Requires board redesign for larger footprint; lacks 6.5 V overvoltage tolerance needed for direct 5 V signal interfacing	Select when SO-8 assembly infrastructure exists and level translation is handled externally
74LVC2G32GM,132	XSON8 (1.35 mm × 1.35 mm); t_PD = 3.2 ns (3.3 V, 50 pF); 5 V tolerant inputs (V_IN ≤ V_CC + 0.5 V)	Smaller than US8 but larger than MicroPak; no 6.5 V overvoltage margin - requires series resistor or clamp for 5 V inputs	Select when footprint size is secondary to supply chain availability and 5 V inputs are pre-conditioned

Compared with SN74LVC2G32DBVR and 74LVC2G32GM,132, the NC7WZ32L8X-L22185 offers superior speed (2.4 ns vs ≥3.2 ns), guaranteed 6.5 V input tolerance enabling direct 5 V–3 V bridging, and the smallest industry-standard logic footprint (1.6 mm × 1.6 mm), making it optimal for miniaturized, mixed-voltage embedded designs.

FAQ

What is the maximum input voltage rating for NC7WZ32L8X-L22185, and does it depend on V_CC?

The NC7WZ32L8X-L22185 supports DC input voltages up to 6.5 V regardless of V_CC level - a key feature enabling direct interfacing between 5 V peripherals and lower-voltage logic domains without external protection. This overvoltage tolerance is explicitly specified in the Absolute Maximum Ratings table and verified across the full −40 °C to +85 °C operating range. The NC7WZ32L8X-L22185 maintains this rating even when V_CC is as low as 1.65 V or 0 V.

Does NC7WZ32L8X-L22185 support power-down mode, and how do I/O behave when V_CC = 0 V?

Yes, the NC7WZ32L8X-L22185 enters a defined power-down state when V_CC = 0 V: all inputs and outputs transition to high-impedance (Hi-Z), preventing back-driving, bus contention, or leakage current. This behavior is documented in the device description and confirmed in the Pin Descriptions section. It ensures safe hot-plug operation and clean power sequencing in multi-rail systems where the NC7WZ32L8X-L22185 may remain powered off while other sections are active.

What is the recommended PCB land pattern for the MicroPak-8 package of NC7WZ32L8X-L22185?

The NC7WZ32L8X-L22185 uses the MicroPak-8 (UQFN8, case 523AY) package with 0.5 mm pitch and 1.6 mm × 1.6 mm body. onsemi recommends a land pattern matching JEDEC MO-255 variation UAAD, including 0.25 mm diameter solder paste openings for all eight terminals and a centered 1.0 mm × 1.0 mm thermal pad with 0.40 mm solder mask clearance. Full mechanical dimensions and land pattern guidance are provided in the "PACKAGE DIMENSIONS" section (page 6) of the NC7WZ32/D datasheet.

Can NC7WZ32L8X-L22185 operate reliably at 1.65 V V_CC, and what performance trade-offs apply?

Yes, the NC7WZ32L8X-L22185 is fully specified from 1.65 V to 5.5 V V_CC. At 1.65 V, propagation delay increases to 10.5 ns (typical, CL = 15 pF), and output drive reduces to ±12 mA (I_OH/I_OL at V_OH/V_OL limits). However, logic thresholds (VIH/VIL) scale correctly, and AC/DC parameters remain guaranteed per the Recommended Operating Conditions table. This makes the NC7WZ32L8X-L22185 suitable for ultra-low-voltage battery-backed subsystems where speed is secondary to energy efficiency.

Is NC7WZ32L8X-L22185 pin-compatible with other TinyLogic UHS dual OR gates like NC7WZ02 or NC7WZ32K8X?

No - the NC7WZ32L8X-L22185 uses the MicroPak-8 (UQFN8) package with specific pinout (Y1, B2, A2, GND, V_CC, Y2, B1, A1), while NC7WZ02 is a dual inverter and NC7WZ32K8X uses the larger US8 (SO-8 compatible) package with different pin assignment. Although functionally identical as dual 2-input OR gates, physical incompatibility means PCB layout changes are required when substituting between NC7WZ32L8X-L22185 and US8-packaged variants. The NC7WZ32L8X-L22185 pinout is fixed and non-interchangeable with other TinyLogic packages.
