Toshiba Electronic Devices & Storage Corporation has expanded its DCL34xx0B series of quad-channel standard digital isolators with four new products designed for industrial equipment, delivering low power consumption, compact packaging, and reliable mid-speed communication. The additions include the DCL340L0B and DCL340H0B, featuring four forward channels, and the DCL342L0B and DCL342H0B, offering two forward and two reverse channels to support bidirectional communication. Designed for applications such as programmable logic controllers (PLCs), actuators, and inverters, the new isolators help prevent failures, abnormal signal propagation, and noise-related malfunctions in circuits operating at different voltage potentials.

The devices are designed to offer a low current consumption of 0.2 mA per channel through utilization of magnetic coupling isolation transmission technology and new circuits. The devices have a minimum isolation voltage of 3,000 Vrms, work at a wide temperature range of -40 °C to 125 °C, and can run under supply voltages ranging between 2.25V and 5.5V. Housed in an industry-standard SSOP16 package, the compact devices address growing space constraints while supporting longer service life and lower system power consumption. The expanded lineup complements Toshiba’s existing digital isolator portfolio, providing flexible channel configurations for diverse industrial applications and reinforcing the company’s commitment to advancing reliable, energy-efficient isolation technologies that support carbon neutrality initiatives.
