Toshiba Electronics Europe has introduced the DCL54xx01A series to its standard digital isolator line-up; the series is composed of ten quad-channel devices that support data rates of up to 150Mbps and operate at temperatures up to 125°C
The target industrial automation applications include programmable logic controllers (PLCs), I/O interfaces, motor control, inverters, and switching power supplies.
The DCL54xx01A series operates from 2.25V to 5.5V and delivers an isolation voltage of 5000Vrms for one minute. Typical propagation delay is 10.9ns, with typical pulse-width distortion being 0.8ns. The devices are in an SOIC16-W package, operating from -40°C to 125°C, making them ideal for industrial systems in high-temperature environments.
Industrial equipment utilising fast-switching power devices is often exposed to high levels of common-mode noise. The DCL54xx01A series uses Toshiba’s magnetic-coupling isolation technology, achieving typical common-mode transient immunity of 150kV/μs to support signal integrity in these environments.
The series is available in 4:0, 3:1, and 2:2 forward/reverse channel-direction configurations, providing flexibility for a variety of isolated communication interfaces. Devices are also available with different default output states and enable-control options to help designers select a device according to application requirements.
The new devices complement Toshiba’s DCL341x0B series of standard digital isolators, designed for mid-speed communication up to 25Mbps in compact SSOP16 packages. The expanded line-up provides designers additional options when selecting devices based on communication speed, operating temperature, and package requirements.
