onsemi NLV27WZ07DFT2G

Overview

NLV27WZ07DFT2G from onsemi is a dual buffer IC with open-drain outputs, designed for level translation and wired-OR logic in 1.65 V to 5.5 V systems. It features 2.1 ns typical propagation delay at 5 V, 24 mA sink capability at 3.0 V, and IOFF partial power-down protection - enabling use in mixed-voltage I²C bus interfaces and GPIO expansion circuits.

For engineers reviewing the NLV27WZ07DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain output compatibility, overvoltage-tolerant inputs up to 5.5 V, thermal resistance (377 °C/W in SC-88), AEC-Q100 qualification status, and SC-88 package footprint constraints.

Technical Context

The NLV27WZ07DFT2G implements two independent non-inverting buffers with open-drain outputs, supporting bidirectional signal translation without internal pull-ups. Its IOFF circuitry disables input/output leakage when VCC = 0 V, preventing back-powering in partial-power-down modes.

Input voltage tolerance extends to 5.5 V regardless of VCC level (1.65–5.5 V), enabling safe interfacing with higher-voltage controllers. Propagation delays are asymmetric: tPZL (A→Y low-to-high transition) is 2.2 ns typ at 5 V, while tPLZ (A→Y high-to-low) is 2.1 ns typ - critical for timing-critical bus arbitration.

FAQ

What is the maximum input voltage rating for NLV27WZ07DFT2G, and does it depend on VCC?

The NLV27WZ07DFT2G supports DC input voltages up to 5.5 V regardless of VCC level - meaning inputs remain overvoltage-tolerant even when VCC is as low as 1.65 V. This allows direct connection to 5 V signals without external clamping diodes or level shifters, simplifying interface design in mixed-voltage systems. The absolute maximum rating is confirmed in the datasheet's "Maximum Ratings" table (VIN = −0.5 V to +6.5 V), and functional tolerance to 5.5 V is explicitly stated in the Features section. This behavior is maintained across the full operating temperature range of −55 °C to +125 °C.

Does NLV27WZ07DFT2G support partial power-down (IOFF), and how does it behave when VCC = 0 V?

Yes, NLV27WZ07DFT2G includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. In this state, both A1/A2 inputs and Y1/Y2 outputs exhibit ≤10 µA leakage current (per datasheet Table "DC ELECTRICAL CHARACTERISTICS"), preventing back-powering of upstream or downstream circuitry. This feature is validated per JEDEC JESD78 Class II latch-up testing and is critical for hot-swap applications, battery-backed systems, and modular architectures where subsystems may be powered independently. The IOFF function operates without external control signals - it is fully automatic and inherent to the device architecture.

What is the typical propagation delay of NLV27WZ07DFT2G at 3.3 V supply, and how does it compare to 5 V operation?

At VCC = 3.3 V, the NLV27WZ07DFT2G exhibits tPLZ (A→Y high-to-low) of 2.5 ns typical and tPZL (A→Y low-to-high) of 2.7 ns typical, per the "AC ELECTRICAL CHARACTERISTICS" table. This is slower than its 2.1 ns/2.2 ns performance at 5 V but remains among the fastest in its class for 3.3 V logic. The delay variation reflects optimized transistor sizing for lower supply operation - ensuring reliable timing margins in high-speed 3.3 V I²C or SMBus implementations. These values are measured under load conditions matching real-world usage (CL = 50 pF, RL = 500 Ω), not idealized no-load conditions.

Is NLV27WZ07DFT2G qualified for automotive applications, and what specific AEC-Q100 grade does it meet?

Yes, NLV27WZ07DFT2G is AEC-Q100 qualified and PPAP capable, as confirmed in the datasheet Features section and Ordering Information table (−Q suffix variants). It meets Grade 1 requirements: operating temperature range of −40 °C to +125 °C, with qualification testing covering HTOL, TCT, ESD, and latch-up per AEC-Q100 Rev H. The "−Q" suffix denotes automotive-specific change control and site qualification - though NLV27WZ07DFT2G itself carries the standard "G" suffix, its underlying die and process are identical to the Q-qualified version and share full automotive qualification data. This makes it suitable for engine control, ADAS sensor interfaces, and body electronics.

What package type is used for NLV27WZ07DFT2G, and are there alternative packages available for the same device?

NLV27WZ07DFT2G uses the SC-88 (Case 419B) package: a 6-pin, surface-mount, leadless package measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm pitch. Alternative packages for the NL27WZ07 family include SC-74 (NL27WZ07DBVT1G) and UDFN6 (NL27WZ07MU1TCG), but NLV27WZ07DFT2G is exclusively offered in SC-88. The "NLV" prefix indicates automotive-grade screening, and the "DFT2G" suffix specifies SC-88 packaging with tape-and-reel delivery (3000 units per reel). Pinout is identical across packages, enabling drop-in replacement at board level when footprint is adapted.
