Toshiba Electronics Europe has expanded its photocoupler portfolio with two new AC input logic-IC couplers capable of data transmission rates up to 5Mbps. The TLP2095 and TLP2098 suit programmable logic controllers, communications equipment, digital interface circuits and other applications where a combination of high-speed data transmission, electrical isolation and low power operation is required.

Designed to support supply voltages from 3.0V to 20V, the TLP2095 and TLP2098 provide buffer logic and inverter logic totem pole outputs respectively. Maximum switching time is just 250ns, and performance is guaranteed at temperatures between -40ºC and 100ºC. The minimum isolation rating for each device is 3750Vrms and internal Faraday shields provide common mode transient immunities of ±15kV/µs.

Both of the new photocouplers are supplied in a compact MFSOP package measuring just 4.4mm x 3.6mm x 2.5mm. This package integrates two GaAlAs infrared LEDs that are optically coupled to a high-gain, high-speed photodetector. A maximum input threshold current of ±3mA and a maximum operating current of 3mA make the couplers ideal for applications where power budgets need to be kept to a minimum.
