TOKYO — (BUSINESS WIRE) — November 18, 2013 — Toshiba Corporation (TOKYO:6502) today announced that it has launched TLP2391, a high-speed photocoupler for servo motors and programmable logic controllers (PLCs) which works with both plus and minus LED currents. Mass production is scheduled to start in December.

PLC applications accept one of two different polarity inputs: sink logic input and source logic input. The TLP2391 supports both sink and source logic by combining two LEDs in inverse parallel, eliminating the need for a bridge circuit. The product supports 10Mbps high speed communications, twice as fast as other Toshiba dual input photocouplers1 allowing use in communications interfaces in industrial applications. The ICs 2.3mA low input current drive (@ VCC = 3.3V) and 1mA low supply current contribute to energy efficiency.
Applications
Programmable logic
controllers (PLC), servo motors, and industrial automation equipment
