Introduction

The HCPL-90xx and HCPL-09xx CMOS digital isolators feature high speed performance and excellent transient immunity specifications. The symmetric magnetic coupling barrier gives these devices a typical pulse width distortion of 2 ns, a typical propagation delay skew of 4 ns and 100 Mbaud data rate, making them the industry’s fastest digital isolators. The single-channel digital isolators (HCPL-9000/-0900) feature an active-low logic output enable. The dual-channel digital isolators are configured as unidirectional (HCPL9030/-0930) and bidirectional (HCPL-9031/-0931), operating in full-duplex mode, making them ideal for digital fieldbus applications. The quad-channel digital isolators are configured as unidirectional (HCPL-900J/-090J), two channels in one direction and two channels in opposite direction (HCPL901J/-091J), and one channel in one direction and three channels in opposite direction (HCPL-902J/-092J). This high channel density makes them ideally suited to isolating data conversion devices, parallel buses, and peripheral interfaces. They are available in 8-pin PDIP, 8-pin Gull Wing, 8-pin SOIC packages, and 16-pin SOIC narrow-body and widebody packages. They are specified over the temperature range of -40°C to +100°C.
