Low pulse width distortion photocouplers target high-speed digital interfaces
The TLP2745 is a buffer logic type (high input to high output) photocoupler, while the TLP2748 is an inverter logic type (high input to low output) coupler, both provide an isolation voltage of minimum 5000 Vrms.
Featuring a high speed propagation delay time of 120 ns (max) for higher operational efficiency while guaranteeing 40 ns (max) pulse width distortion and 70 ns (max) propagation delay skew, the ICs allow the reduction of inverter dead time, contributing to an overall improvement in power efficiency.
In addition, by guaranteeing a threshold input current of 1.6mA (max), they allow bufferless direct drive from microcomputers, and as such a reduction in energy consumption and cost. With an operating temperature range of -40 to 110°C, and a wide supply voltage range (VCC=4.5 to 30 V), these ICs are suited to communication interfaces (such as RS232, RS422, and RS485) including use in industrial applications, and data transmission solutions between circuits with different voltages. The TLP2745 and TLP2748 are housed in a 10×3.8×2.1mm SO6L package.
