Product details

Overview

NC7WZ241L8X-L22185 from onsemi is a dual non-inverting buffer IC with asymmetric 3-STATE output control (one active-low OE, one active-high OE), enabling bidirectional transceiver functionality in space-constrained designs. 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 - used in voltage-level translation and bus interface circuits.

For engineers reviewing the NC7WZ241L8X-L22185 datasheet, pinout, applications, or equivalent options, key selection factors include its dual-enable transceiver architecture, overvoltage-tolerant inputs (up to 5.5 V independent of V_CC), 3-STATE output overvoltage tolerance, US8/MicroPak package compatibility, and 1.6×1.6 mm UQFN8 footprint.

Technical Context

The NC7WZ241L8X-L22185 implements two independent buffer channels sharing a single supply rail, with logically complementary enable paths: OE (active-low) controls Y1, while OE (active-high) controls Y2. This asymmetry eliminates external logic inversion for half-duplex bus control.

Its advanced CMOS process enables rail-to-rail input tolerance (−0.5 V to 6.5 V), power-down high-impedance I/O states at V_CC = 0 V, and patented noise/EMI reduction circuitry - critical for mixed-voltage signal routing in portable and industrial systems operating from −40 °C to +85 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - supports interoperability between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters.
t_PD (Typ)	2.6 ns into 50 pF at 5 V - enables sub-400 MHz signal routing in high-speed digital interfaces.
I_OH/I_OL	±24 mA at 3 V - drives standard TTL loads and multiple CMOS inputs without buffering.
Input Tolerance	Up to 5.5 V independent of V_CC - allows safe 5 V-to-3.3 V translation when V_CC = 3.3 V.
3-STATE Output Tolerance	0 V to 5.5 V in high-impedance state - prevents latch-up during hot-swap or partial-power-down conditions.
Package	UQFN8 (1.6 × 1.6 mm, 0.5 mm pitch) - reduces PCB area by >60% vs. legacy SOIC-8 and enables fine-pitch routing.

Pinout & Package

NC7WZ241L8X-L22185 is housed in an 8-pin ultra-thin quad flat no-lead (UQFN8) package per JEDEC MO-255 UAAD, with 0.5 mm pitch, 1.6 mm × 1.6 mm body, and exposed thermal pad (Case 523AY). Pin 1 identification is determined by top-mark orientation (T7).

Pin/Terminal	Circuit Role	Design Meaning
1 (OE)	Active-low output enable for Y1	Drives Y1 low-impedance when logic LOW; Y1 enters 3-STATE when HIGH - enables master-side control in bidirectional buses.
2 (Y1)	Buffered output channel 1	Non-inverted replica of A1 input when OE = LOW; high-impedance otherwise - used for data transmit path.
3 (A2)	Input channel 2	Accepts logic signals up to 5.5 V regardless of V_CC - supports mixed-supply interfacing without external clamping.
4 (GND)	Ground reference	Return path for all I/O and internal logic; must be connected to system ground plane for EMI control and noise immunity.
5 (V_CC)	Power supply	Single supply rail powering both buffers and enable logic; decoupling capacitor (0.1 µF) required within 2 mm of this pin.
6 (Y2)	Buffered output channel 2	Non-inverted replica of A2 input when OE = HIGH; high-impedance otherwise - used for data receive path.
7 (A1)	Input channel 1	Primary input for first buffer; electrically identical to A2 in voltage tolerance and loading characteristics.
8 (OE)	Active-high output enable for Y2	Drives Y2 low-impedance when logic HIGH; Y2 enters 3-STATE when LOW - complements OE for full transceiver handshake.

Key Features

Feature	Design Value
Dual asymmetric 3-STATE control	Eliminates need for external inverters in half-duplex bus transceivers by integrating complementary OE logic.
Overvoltage-tolerant inputs	Withstands 5.5 V inputs at any valid V_CC (1.65–5.5 V), enabling robust 5 V → 3.3 V level translation without external components.
3-STATE output overvoltage tolerance	Outputs remain safe and non-latching when driven above V_CC (up to 5.5 V) while disabled - essential for hot-plug and multi-supply backplanes.
Ultra-low propagation delay	2.6 ns typical t_PD at 5 V ensures timing closure in high-frequency clock distribution and data strobe paths.
Pb-free MicroPak packaging	RoHS-compliant 1.6 × 1.6 mm UQFN8 footprint reduces board area by 75% vs. SOIC-8 and improves thermal performance via exposed pad.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-buffer transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G241DBVR	Both OEs active-low; requires external inverter for asymmetric control; 3.3 V optimized (1.65–5.5 V); 3.5 ns t_PD at 3.3 V.	Lacks native transceiver enable asymmetry; better suited for symmetric dual-enable systems.	Select when board layout already includes inverters or when strict 3.3 V operation dominates.
74LVC2G126GW,125	Single-channel with 3-STATE; requires two units for dual function; 2.9 ns t_PD at 3.3 V; same 1.65–5.5 V range.	Higher component count and PCB area; no integrated dual-channel timing correlation.	Select when channel independence is critical and skew matching between buffers is not required.

Compared with SN74LVC2G241DBVR and 74LVC2G126GW,125, the NC7WZ241L8X-L22185 uniquely integrates complementary OE logic in a single UQFN8 package, delivering lower system-level latency, reduced board area, and guaranteed inter-channel skew - making it optimal for compact transceiver implementations where timing alignment and minimal component count are design priorities.

FAQ

What is the maximum input voltage rating for NC7WZ241L8X-L22185, and does it depend on V_CC?

The NC7WZ241L8X-L22185 supports DC input voltages from −0.5 V to 6.5 V, with overvoltage-tolerant inputs rated up to 5.5 V independent of V_CC. This means inputs remain safe and functional even when driven at 5.5 V while V_CC is as low as 1.65 V - a key enabler for 5 V-to-3.3 V level translation without external components. Absolute maximum ratings must never be exceeded in continuous operation.

How does the dual-enable architecture of NC7WZ241L8X-L22185 differ from standard dual buffers?

The NC7WZ241L8X-L22185 features asymmetric 3-STATE control: OE (pin 1) is active-low for Y1, while OE (pin 8) is active-high for Y2. This eliminates the need for external inverters in transceiver applications, unlike standard dual buffers (e.g., SN74LVC2G241) that use identical OE polarities. The integrated complementary logic simplifies PCB routing and reduces component count in bidirectional data paths.

Can NC7WZ241L8X-L22185 operate at 1.8 V, and what performance metrics apply at that voltage?

Yes, NC7WZ241L8X-L22185 is fully specified from 1.65 V to 5.5 V V_CC. At 1.8 V ±0.15 V, propagation delay is 12.0 ns (max) into 15 pF, output drive is ±16 mA (min), and input thresholds are VIH ≥ 0.65 × V_CC and VIL ≤ 0.35 × V_CC. These values ensure reliable operation in low-power IoT and wearable systems where supply headroom is constrained.

What is the thermal resistance (θ_JA) of the UQFN8 package used in NC7WZ241L8X-L22185?

The NC7WZ241L8X-L22185 in its MicroPak UQFN8 package (Case 523AY) has a junction-to-ambient thermal resistance (θ_JA) of 232 °C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad with 2 vias; actual thermal performance improves with enhanced PCB copper area and thermal vias beneath the exposed pad.

Is NC7WZ241L8X-L22185 pin-compatible with NC7WZ241K8X or other variants in the same family?

No - NC7WZ241L8X-L22185 uses the 8-pin UQFN8 (1.6 × 1.6 mm) package, while NC7WZ241K8X uses the larger 8-lead US8 (3.1 mm wide) package. Although both share identical logic functionality and pin functions, their footprints, soldering profiles, and mechanical dimensions are incompatible. Board redesign is required when migrating between these packages.
