Description

Product Overview

The onsemi NC7WZ17P6X-L22347 is a TinyLogic UHS dual buffer with Schmitt trigger inputs in an SC-70-6 (SOT-363) package. Operating from 1.65V to 5.5V, it provides 3.0 ns propagation delay at 5V with plus/minus 24 mA output drive. The Schmitt trigger inputs convert slow or noisy signals into clean, jitter-free outputs, ideal for signal conditioning and clock buffering in high-density designs.

Product Introduction:NC7WZ17P6X-L22347 Product Introduction

The onsemi NC7WZ17P6X-L22347 is a TinyLogic UHS (Ultra High Speed) dual non-inverting buffer with Schmitt trigger inputs, housed in the ultra-compact SC-70-6 (SOT-363) package. The device operates from 1.65V to 5.5V and achieves 3.0 ns propagation delay at 5V, making it one of the fastest buffers in its class. The Schmitt trigger input architecture provides approximately 0.6V of hysteresis at 5V, converting slow-rising, noisy, or distorted input signals into clean, jitter-free outputs with sharp transitions. This makes the device ideal for conditioning signals from mechanical switches, optical sensors, and long PCB traces. The high output drive of plus/minus 24 mA enables clock distribution and bus driving. Inputs are overvoltage tolerant to 5.5V independent of VCC, supporting live insertion and level-shifting between voltage domains.

Working Principle:NC7WZ17P6X-L22347 Working Principle

The NC7WZ17P6X-L22347 contains two independent non-inverting buffer channels, each with Schmitt trigger input conditioning. The Schmitt trigger uses two comparator thresholds: a higher threshold (VT+) for rising input signals and a lower threshold (VT-) for falling input signals. The difference between VT+ and VT- is the hysteresis voltage (approximately 0.6V at 5V). When the input rises above VT+, the output transitions from LOW to HIGH. When the input falls below VT-, the output transitions from HIGH to LOW. This hysteresis prevents output oscillation when the input signal is slow or noisy — the output only changes state when the input definitively crosses a threshold. The CMOS output buffer provides plus/minus 24 mA drive capability with symmetrical source/sink performance. The overvoltage-tolerant input structure allows input signals up to 5.5V even when VCC is at 1.65V, enabling the device to function as a level shifter from 5V to 1.8V domains.
