Toshiba Launches a 10 Mbps Logic Output Photocoupler for PLCs

Toshiba TLP2363

Device is housed in a 5-pin SO6 package and conforms to IEC 61131

Toshiba Electronics Europe has launched a new high-speed 10 Mbps logic output photocoupler for 24 V digital input programmable logic controller (PLC) and other measurement and control equipment.

Toshiba - TLP2363

The new TLP2363 requires a supply current of just 4 mA and is rated for a wide operating temperature range (–40 to +105 °C). The threshold input current (IFHL) is specified with min, 0.3 mA and max. 2.4 mA thereby ensuring conformance to the digital input standard IEC 61131-2 type 1. Uniquely for this type of device, all that is required to complete the design is a bridge diode and a suitable resistor for current control. The short propagation delay of just 80 ns is ideal for use with high-speed systems.

The photocoupler delivers a clear ‘high’ or ‘low’ on the output by suppressing chatter noise, even with a slow-moving input signal of 60 s or less with a long rising or falling edge. As a result, there is no need for any waveform shaping circuitry, reducing the number of components that saves PCB area and cost.

Despite being housed in a small and thin 5-pin SO6 package with a max. height of 2.3 mm, the device offers a minimum isolation voltage of 3750 Vrms. The common footprint allows designers to replace products from other manufacturers, allowing them to take advantage of the improved specification of the Toshiba TLP2363.

Shipments of the new photocoupler are started.
