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