onsemi NL27WZ17MU1TCG

Overview

NL27WZ17MU1TCG from onsemi is a dual non-inverting Schmitt-trigger buffer IC operating from 1.65 V to 5.5 V, delivering 3.7 ns typical propagation delay at 5 V, ±32 mA output drive capability, and overvoltage-tolerant inputs/outputs up to 5.5 V. It enables robust signal conditioning in noisy industrial sensor interfaces and low-voltage logic level translation.

For engineers reviewing the NL27WZ17MU1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (1.65–5.5 V), hysteresis thresholds (e.g., VT+ = 3.3 V / VT− = 1.2 V at 5.5 V), IOFF partial power-down support, UDFN6 1.45×1.0 mm package footprint, and AEC-Q100 qualification for automotive-adjacent designs.

Technical Context

The NL27WZ17MU1TCG implements two independent Schmitt-trigger input buffers with hysteresis-VT+ and VT− vary with VCC (e.g., 1.0–3.6 V and 0.2–1.9 V respectively across 1.65–5.5 V)-ensuring noise immunity in slow-rising or noisy digital signals. Each channel provides rail-to-rail output swing and tri-state capability via inherent logic-level control.

It supports IOFF circuitry that disables I/O leakage when VCC = 0 V, enabling live insertion and bus isolation. Input capacitance is 2.5 pF and output capacitance is 4.0 pF at 5.5 V, minimizing loading on driving stages while maintaining fast edge integrity under 15 pF load conditions.

FAQ

What is the maximum input voltage the NL27WZ17MU1TCG can tolerate when VCC = 1.8 V?

The NL27WZ17MU1TCG features overvoltage-tolerant inputs and outputs rated up to 5.5 V regardless of VCC level. When VCC = 1.8 V, inputs may safely accept 0–5.5 V signals without damage or latch-up, eliminating external clamping components in mixed-voltage systems. This behavior is explicitly guaranteed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and confirmed in the Recommended Operating Conditions (VIN = 0 to 5.5 V).

Does the NL27WZ17MU1TCG support true tri-state operation?

No, the NL27WZ17MU1TCG does not implement active tri-state control. Its outputs are always driven high or low based on input logic state. However, the IOFF feature provides functional isolation: when VCC = 0 V, both inputs and outputs enter a high-impedance leakage-limited state (<10 µA), enabling partial power-down bus sharing. This is distinct from programmable output enable but serves similar system-level isolation goals.

What is the thermal resistance (θJA) of the NL27WZ17MU1TCG in its UDFN6 package?

The NL27WZ17MU1TCG in the UDFN6 1.45×1.0 mm package (Case 517AQ) has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value assumes use of the exposed copper thermal pad soldered to a solid ground plane-failure to connect the pad degrades thermal performance significantly.

Can the NL27WZ17MU1TCG be used in AEC-Q100 compliant automotive designs?

Yes, the NL27WZ17MU1TCG is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient) and PPAP capable. While the base part number lacks the "−Q" suffix, the datasheet explicitly states that "−Q Suffix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable" applies to the NL27WZ17 family-including NL27WZ17MU1TCG-as confirmed in the Features section and Ordering Information table.

What is the typical input hysteresis voltage (VH) of the NL27WZ17MU1TCG at VCC = 3.3 V?

At VCC = 3.3 V, the NL27WZ17MU1TCG exhibits a typical input hysteresis voltage (VH) of 1.2 V, with a minimum of 0.4 V and maximum of 1.2 V across temperature (−55 °C to +125 °C) per the DC Electrical Characteristics table. This hysteresis ensures reliable switching in presence of up to ±600 mV of noise on the input signal, making it ideal for mechanical switch or slow-rise sensor interfacing.
