onsemi NC7WZU04P6X-L22347

Overview

NC7WZU04P6X-L22347 from onsemi is a dual unbuffered inverter IC in SC-88 package, designed for crystal oscillator and analog applications where single-stage gain and linear-region operation are required. It operates across 1.65 V to 5.5 V supply, delivers ±32 mA output drive at 4.5 V, and features high-impedance inputs at V_CC = 0 V - enabling safe hot-insertion in mixed-voltage systems.

For engineers reviewing the NC7WZU04P6X-L22347 datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered topology for oscillator feedback paths, broad V_CC range compatibility with 1.8 V/2.5 V/3.3 V/5 V logic domains, low ICC (<1 µA at 5 V), and SC-88 footprint constraints in space-constrained timing circuits.

Technical Context

The NC7WZU04P6X-L22347 implements two independent unbuffered inverter stages - each consisting of a single CMOS inverter pair without internal buffering - enabling direct use in Pierce or Colpitts oscillator topologies where phase shift and gain control depend on external crystal and load capacitors. Its input structure tolerates up to 5.5 V regardless of V_CC, supporting level-shifting between disparate voltage domains.

Propagation delay ranges from 2.2 ns (typical, 5.0 V, CL = 15 pF) to 9.8 ns (max, 1.65 V, CL = 15 pF), with input capacitance ≤3 pF and power dissipation capacitance of 5.5 pF at 5.0 V. The device's linear-region conduction behavior requires thermal derating when used as an analog amplifier or oscillator active element.

FAQ

What is the primary circuit role of the NC7WZU04P6X-L22347 in oscillator designs?

The NC7WZU04P6X-L22347 serves as the gain element in Pierce and Colpitts crystal oscillator configurations. Its unbuffered single-stage inverter topology provides the precise phase shift and gain needed to sustain oscillation without introducing additional delay or distortion - a requirement that buffered inverters cannot meet. This makes NC7WZU04P6X-L22347 indispensable in RTC and MCU clock circuits where frequency accuracy and startup reliability are critical.

Can the NC7WZU04P6X-L22347 operate safely with a 5 V input signal while powered from a 1.8 V supply?

Yes - the NC7WZU04P6X-L22347 inputs tolerate voltages up to 5.5 V independent of V_CC. When V_CC = 1.8 V, A1 and A2 pins accept 0–5.5 V signals without damage or latch-up, enabling robust level-shifting between 5 V control logic and 1.8 V system domains. This capability is confirmed in the Absolute Maximum Ratings table and verified across temperature ranges in the datasheet.

Why does the NC7WZU04P6X-L22347 specify a maximum ICC of 10 µA over temperature, while typical ICC is <1 µA?

The NC7WZU04P6X-L22347 quiescent current increases with junction temperature and process variation. While typical ICC remains below 1 µA at 25°C and 5 V, the datasheet guarantees ≤10 µA across −40°C to +85°C - ensuring predictable power budgeting in thermally demanding environments like enclosed industrial sensors. This specification directly supports battery-life modeling for NC7WZU04P6X-L22347-based RTC designs.

Is the NC7WZU04P6X-L22347 pin-compatible with other SC-88 dual inverters such as the NC7SZ04?

No - the NC7WZU04P6X-L22347 uses a non-standard SC-88 pinout optimized for oscillator layout: Pin 1 = A1, Pin 2 = GND, Pin 3 = A2, Pin 4 = Y2, Pin 5 = V_CC, Pin 6 = Y1. In contrast, NC7SZ04 follows standard logic ordering (A1, Y1, GND, V_CC, A2, Y2). PCB redesign is required to substitute NC7WZU04P6X-L22347 into existing NC7SZ04 footprints.

How should thermal management be handled when using the NC7WZU04P6X-L22347 in linear-mode analog applications?

When biased in the linear region (e.g., as an analog inverter amplifier), the NC7WZU04P6X-L22347 exhibits simultaneous conduction in its output MOSFETs, increasing power dissipation. To avoid exceeding the SC-88 package's 332 mW limit, keep ambient temperature ≤70°C, limit continuous linear operation duty cycle, and ensure ≥200 mm² copper pour under the package. Derating curves in the datasheet confirm safe operation only below 50% of max PD at 85°C ambient.
