Toshiba launches 10Mbps logic output photocoupler for PLCs

Toshiba has launched a 10Mbps logic output photocoupler for 24V digital input PLCs along with other measurement and control equipment.

The TLP2363 requires a supply current of 4mA and is rated for an operating temperature range of -40 to 105℃. The threshold input current (IFHL) is specified with min, 0.3mA and max. 2.4mA, which conforms to the digital input standard IEC 61131-2 type 1.

To complete the design, a bridge diode and a suitable resistor for current control will be required. The device has a propagation delay of 80ns, 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, the manufacturer claims, there is no need for any waveform shaping circuitry.

The device comes in a 5-pin SO6 package with a maximum height of 2.3mm, the device offers a minimum isolation voltage of 3750Vrms. The common footprint allows designers to replace products from other manufacturers if they choose.
