Product details
Overview
NL27WZ125USG-F22190 from onsemi is a dual noninverting buffer with 3-state outputs, operating from 1.65 V to 5.5 V supply. It delivers 2.4 ns typical propagation delay at 5 V, supports ±24 mA drive at 3.0 V, and features IOFF partial power-down protection - used in voltage-level translation and bus isolation in mixed-supply digital systems.
For engineers reviewing the NL27WZ125USG-F22190 datasheet, pinout, applications, or equivalent options, key selection criteria include 3-state enable timing (tPZH/tPHZ ≤ 5.8 ns), overvoltage-tolerant inputs up to 5.5 V, and US8 package compatibility with space-constrained PCB layouts.
Technical Context
The NL27WZ125USG-F22190 implements two independent noninverting buffers, each with separate 3-state output enable (OE1/OE2) control. Its CMOS design ensures rail-to-rail input tolerance and low dynamic power via CPD = 9–11 pF across 3.3 V/5.5 V operation.
It supports partial power-down (IOFF < 10 µA when VCC = 0 V) and operates across −55 °C to +125 °C, meeting AEC-Q100 requirements for automotive use when ordered with -Q suffix - though NL27WZ125USG-F22190 itself is commercial-grade per marking and ordering data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| tPD (typ) | 2.4 ns at VCC = 5 V - ensures minimal signal delay in high-speed data path buffering. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives standard TTL loads and multiple CMOS inputs without external buffering. |
| Input Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage peripherals in mixed-rail systems. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents back-driving and signal corruption during system power sequencing. |
| Operating Temp | −55 °C to +125 °C - supports industrial and under-hood automotive environments when qualified variant is selected. |
Pinout & Package
Package: US8 (8-pin ultra-small surface-mount, case 493, 2.1 mm × 2.0 mm × 0.55 mm, lead pitch 0.5 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Output Enable 1 | Active-low control for Buffer 1 output; places Y1 in high-impedance state when high. |
| 2 (A1) | Input 1 | Noninverting input for first buffer stage; accepts overvoltage-tolerant logic signals. |
| 3 (Y2) | Output 2 | Inverted-output pin assignment reflects physical layout - Y2 is pin 3 per Figure 2, not functional inversion. |
| 4 (GND) | Ground | Reference return path for both buffers; must be low-inductance connection for noise immunity. |
| 5 (A2) | Input 2 | Noninverting input for second buffer stage; electrically isolated from A1 except via shared VCC/GND. |
| 6 (Y1) | Output 1 | Buffered replica of A1; driven only when OE1 is low; tri-stated when OE1 is high. |
| 7 (OE2) | Output Enable 2 | Active-low control for Buffer 2 output; independent timing from OE1 enables staggered bus control. |
| 8 (VCC) | Supply Voltage | Single positive supply for both buffers; decoupling capacitor required within 1 cm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65 V to 5.5 V operation enables drop-in replacement across legacy and modern logic families without redesign. |
| Low propagation delay | 2.4 ns typical at 5 V ensures sub-400 MHz clock domain compatibility for data sampling and synchronization. |
| Overvoltage-tolerant inputs | Inputs withstand up to 5.5 V independently of VCC - eliminates need for external level-shifters in mixed-voltage I/O interfaces. |
| IOFF partial power-down | Sub-10 µA leakage during VCC = 0 V prevents current backflow into powered sections during hot-swap or partial shutdown. |
| US8 footprint | 2.1 mm × 2.0 mm package reduces board area by >40% vs. SOIC-8 while maintaining thermal resistance of 250 °C/W. |

FAQ
What is the maximum operating temperature for NL27WZ125USG-F22190?
The NL27WZ125USG-F22190 is rated for operation from −55 °C to +125 °C per its Recommended Operating Conditions table. This full industrial temperature range is validated across all electrical parameters in the datasheet, including propagation delay, output drive, and leakage currents - ensuring reliable performance in under-hood automotive and factory-floor environments where ambient temperatures exceed 85 °C.
Does NL27WZ125USG-F22190 support 1.8 V logic levels?
Yes, NL27WZ125USG-F22190 fully supports 1.8 V logic operation: its VCC range starts at 1.65 V, VIH is defined as 0.65 × VCC (so ~1.17 V at 1.8 V), and VOL remains ≤0.28 V at 1.8 V with 12 mA load. Input thresholds scale with supply, enabling clean interfacing with 1.8 V FPGAs and microcontrollers without level shifters.
Is NL27WZ125USG-F22190 pin-compatible with SN74LVC2G125?
No, NL27WZ125USG-F22190 is not pin-compatible with SN74LVC2G125. While both use US8 packages, their pinouts differ: NL27WZ125USG-F22190 places OE1 on pin 1 and Y2 on pin 3, whereas SN74LVC2G125 places A1 on pin 1 and Y1 on pin 3. PCB layout must be verified against each device's official pinout diagram before substitution.
What does the "F22190" suffix in NL27WZ125USG-F22190 indicate?
The "F22190" suffix in NL27WZ125USG-F22190 is a date/batch code per onsemi's marking convention: "F" denotes assembly location, "22" is year (2022), "190" is day-of-year (July 9, 2022). It is not a functional variant identifier - electrical and thermal specifications match the base NL27WZ125USG part number as defined in datasheet NL27WZ125/D Rev. 15.
Can NL27WZ125USG-F22190 drive a 50 pF capacitive load at 10 MHz?
Yes, NL27WZ125USG-F22190 can reliably drive a 50 pF load at 10 MHz: AC Electrical Characteristics specify tPLH/tPHL ≤ 6.0 ns (max) at CL = 50 pF and VCC = 3.0–3.6 V, and CPD = 9–11 pF confirms low dynamic power draw.
