TLP718F(F)

Overview

The Toshiba TLP718F(F) is a high-speed optocoupler featuring an infrared emitting diode and an integrated high-gain, high-speed photodetector. It utilizes a 6-pin SDIP gull-wing package with a single channel configuration. Key electrical parameters include a 5000 Vrms insulation voltage and a minimum common mode transient immunity of 10kV/µs. The device operates with a forward current of 5 mA and a forward voltage of 1.6 V. Signal propagation characteristics are defined by rise and fall times of 30 ns each. The output stage employs a totem pole structure, supporting logic-level signaling. Operating temperatures range from -40°C to +100°C.
