The TOSHIBA TLP559 consists of a GaAℓAs high−output light emitting diode and a high speed detector of one chip photo diode−transistor. This unit is 8−lead DIP package.

TLP559 has no internal base connection, and a faraday shield integrated on the photodetector chip provides an effective common mode noise transient immunity.

​​​​​​​So this is suitable for application in noisy environmental condition.

• Isolation voltage: 2500Vrms (min.)

• Switching speed: tpHL = 0.3μs (typ.)

tpLH = 0.5μs (typ.) (RL= 1.9kΩ)

• TTL compatible

• UL recognized: UL1577, file No.E67349
