High Speed Digital Isolator

Currently Viewing:

The quad channel 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 quad channel digital isolators are configured as unidirectional (HCPL-900J/090J). These high channel density make them ideally suited to isolating data conversion devices, parallel buses and peripheral interfaces.

They are available in 8-pin PDIP, 8-pin Gul Wing, 8-pin SOIC packages, and 16-pin SOIC narrow-body and wide-body packages. They are specified over the temperature range of -40oC to 100oC. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation, which may be induced by ESD.
