Product details

Overview

NC7SZU04P5X-L22057 from onsemi is a single unbuffered inverter in the TinyLogic UHS family, designed specifically for crystal oscillator and analog applications where linear-region operation is required. It operates across 1.65 V to 5.5 V V_CC, delivers ±32 mA output drive at 4.5 V, and achieves 4.5 ns typical propagation delay (V_CC = 3.3 V, C_L = 15 pF), enabling high-frequency timing circuits.

For engineers reviewing the NC7SZU04P5X-L22057 datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered topology for oscillator feedback, low quiescent current (<2 µA at 5.5 V), SC-88A package compatibility, and verified performance across industrial temperature range (−40°C to +85°C).

Technical Context

The NC7SZU04P5X-L22057 implements an unbuffered CMOS inverter stage-lacking internal buffering-to support stable negative resistance in Pierce-type crystal oscillator configurations. Its symmetric output drive (±32 mA) and low input capacitance (4.5 pF) minimize phase shift and loading effects critical for oscillator loop gain stability.

Unlike buffered logic inverters, this device exhibits controlled linear-region conduction when biased near V_CC/2, enabling analog amplification and sustained oscillation without external biasing networks. It is not intended for standard digital logic inversion in rail-to-rail switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifting
t_PLH/t_PHL	4.5 ns typical at 3.3 V, 15 pF - enables >100 MHz fundamental crystal oscillator operation
I_OH/I_OL	±32 mA at 4.5 V - provides sufficient drive for low-ESR crystals and small-signal analog loads
I_IN	±1 µA max at 5.5 V - ensures minimal loading on sensitive oscillator node or feedback network
C_IN	4.5 pF - reduces capacitive loading on crystal terminals, preserving frequency accuracy and start-up margin
I_CC	<2 µA at 5.5 V, 25°C - enables ultra-low-power oscillator designs suitable for battery-backed real-time clocks

Pinout & Package

NC7SZU04P5X-L22057 is packaged in SC-88A (Case 419A-02), a 5-pin surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm, optimized for space-constrained oscillator layouts and high-density PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No-connect terminal - must be left floating or grounded per layout; no internal connection
2	A	Inverting input - connects directly to crystal output or feedback node; requires clean, low-inductance trace
3	GND	Digital ground reference - must be tied to low-impedance ground plane adjacent to crystal pads
4	Y	Inverting output - drives crystal input or next-stage amplifier; sensitive to parasitic capacitance
5	V_CC	Supply voltage - bypassed with 100 nF ceramic capacitor placed within 2 mm of pin

FAQ

What is the primary design purpose of the NC7SZU04P5X-L22057?

The NC7SZU04P5X-L22057 is engineered as an unbuffered inverter for crystal oscillator and analog applications-not general-purpose digital logic. Its circuit topology enables stable negative resistance in Pierce oscillator configurations, with verified performance across −40°C to +85°C and 1.65 V to 5.5 V V_CC. The NC7SZU04P5X-L22057 avoids internal buffering to preserve phase integrity and support linear-region operation essential for sustained oscillation.

Can the NC7SZU04P5X-L22057 be used as a standard digital inverter?

No-the NC7SZU04P5X-L22057 is not optimized for rail-to-rail digital switching. Its unbuffered structure causes significant simultaneous conduction and elevated power dissipation when driven hard between logic states. Datasheet Note 5 explicitly warns against operating outside oscillator or analog linear-region use cases. For standard logic inversion, buffered alternatives like NC7WZ04 are recommended. The NC7SZU04P5X-L22057 must be applied per its intended function to ensure reliability.

What is the significance of Pin 1 being labeled "NC" on the NC7SZU04P5X-L22057?

Pin 1 of the NC7SZU04P5X-L22057 is a true no-connect terminal with no internal bond wire or silicon connection. It may be left floating or tied to GND for mechanical stability-neither action affects electrical performance. This NC pin allows pin-compatible placement with other TinyLogic variants while maintaining SC-88A footprint consistency. The NC7SZU04P5X-L22057 datasheet confirms no internal linkage, and routing to ground introduces no risk of shorting or leakage.

How does the NC7SZU04P5X-L22057 achieve low power consumption in oscillator mode?

The NC7SZU04P5X-L22057 achieves sub-2 µA quiescent current (I_CC) through advanced CMOS process optimization and minimized transistor leakage paths. In crystal oscillator use, it operates in a self-biased linear region where average current draw remains extremely low-unlike digital switching modes that induce dynamic ICCD spikes. This behavior is validated across V_CC = 1.65–5.5 V and TA = −40°C to +85°C. The NC7SZU04P5X-L22057's low I_CC directly extends battery life in RTC and sensor applications.

Is the NC7SZU04P5X-L22057 RoHS compliant and lead-free?

Yes-the NC7SZU04P5X-L22057 is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. The "M" suffix in the top mark (ZU4M) explicitly denotes Pb-free packaging, and onsemi's datasheet confirms compliance in the Features section. All SC-88A units shipped under part number NC7SZU04P5X-L22057 meet current environmental regulations without exception or exemption.
