ACML-7420

3.3V/5V 100MBd High Speed CMOS Digital Isolator

Currently Viewing:

The ACML-74x0 series, from Avago Technologies, is a family of multi-channel high-speed CMOS digital isolators. Using magnetic coupling through a thick insulation barrier, these CMOS digital isolators help enable high-speed transmissions without compromise to isolation performance. These CMOS digital isolators consume a small amount of power, even at high data rates, yet provide transient immunity performance in compact surface-mount packages. These CMOS digital isolators are qualified to a maximum propagation delay of 36ns and a maximum pulse width distortion of 3ns. They are also capable of running at a 100MBd data rate.

Our CMOS digital isolator devices are available in 16-pin SOIC wide-body packages. They operate at dual 3.3V or 5V supply voltages. The DC and timing are specified over the temperature range of -40° C to +105° C. The quad-channel ACML-7420 CMOS digital isolator is configured as a bi-directional device, with two channels in one direction and two channels in the reverse direction. The ACML-7420, along with the ACML-7400 and ACML-7410 digital isolators, is also built using CMOS input buffers and CMOS output drivers helping to eliminate the need for both input limiters and output pull-up resistors. Refresh circuitry is built in to ensure DC-correctness.
