TLP551

TOSHIBA Photocoupler IRED & Photo IC TLP551 Controllers Interfaces for Calculators and Control Devices Noise Attenuation in Measurement and System Devices Signal Transmission between circuits of different potential TLP551 Unit: mm The TOSHIBA TLP551 consists of a high-output infrared emitting diode and a high speed detector of one chip photo diode-transistor. This unit is 8lead DIP. TLP551 has an internal base connection. This base pin should be used for analog application or enable operation. Isolation voltage: 2500 Vrms (min) Switching speed: tpHL = 0.5 μs (typ.) tpLH = 0.6 μs (typ.) (RL = 1.9 kΩ) TTL compatible If the base pin is open, external noise will cause interference to the output signal. In this scenario, TLP550 will be recommended.
