Toshiba launches a 10Mbps logic output photocoupler for PLCs

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

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

The new TLP2363 requires a supply current of just 4mA and is rated for a wide operating temperature range (-40 to +105℃). The threshold input current (IFHL) is specified with min, 0.3mA and max. 2.4mA 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 80ns 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 60s 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 2.3mm, the device offers a minimum isolation voltage of 3750Vrms. The common footprint allows designers to replace products from other manufacturers, allowing them to take advantage of the improved specification of the Toshiba TLP2363.
