Toshiba has announced two new high-speed photocouplers that deliver isolated switching in accordance with international safety standards in packages that are half the size of 8-pin DIP alternatives with the same performance. The new 6-pin SDIP (shrink DIP) TLP715 and TLP718 photocouplers are ideal for applications such as isolated bus drivers, high-speed line receivers and microprocessor system interfaces. Offering maximum switching speeds of just 250ns, the TLP715 and TLP718 provide buffer (non-inverter) and inverter logic outputs respectively.
Both of the new couplers have minimum isolation ratings of 5000Vrms despite compact physical dimensions of just 6.8mm x 4.58mm x 3.65mm. This allows designers to meet the reinforced insulation class requirements of international safety standards. An internal Faraday shield provides a guaranteed common-mode transient immunity of ±10kV/µs.
Featuring totem-pole outputs, the TLP715 and TLP718 can provide either source and sink driving. Both devices will operate with an input of between 4.5V and 20V, while maximum input current is 3mA.
Toshiba’s new couplers are based around a GaAlAs infrared LED that is optically coupled to a high-gain, high-speed photodetector. International certifications include UL1577, c-UL, TÜV and VDE.
