TLP2530,TLP2531 TOSHIBA Photocoupler GaAAs Ired & Photo IC TLP2530, TLP2531 Digital Logic Isolation Unit in mm Line Receiver Power Supply Control Switching Power Supply Transistor Inverter The TOSHIBA TLP2530 and TLP2531 dual photocouplers consist of a pair of GaAAs light emitting diode and integrated photodetector. This unit is 8lead DIP. Separate connection for the photodiode bias and output transistor collectors improve the speed up to a hundred times that of a conventional phototransistor coupler by reducing the basecollector capacitance. z TTL compatible z Switching speed: t =0.3s, t =0.3s(typ.) pHL pLH ( R =1.9k ) L TOSHIBA 1110C4 z Guaranteed performance over temp: 0~70C Weight: 0.54 g (typ.) z Isolation voltage: 2500 Vrms(min.) z UL recognized: UL1577, file no.
