TLP2348(TPL,E(T – Logic Output Optocoupler – Toshiba

About this part

The Toshiba TLP2348 is a single-channel, high-speed logic-output optocoupler (photocoupler) designed to transmit digital signals across an isolation barrier in noisy industrial environments. It pairs a high-output GaAlAs infrared LED with a high-gain, high-speed photo-IC detector that drives an inverting, totem-pole logic output, delivering clean isolated logic transitions at data rates up to 10 Mbps. With 3750 Vrms isolation and an internal Faraday shield for high common-mode transient immunity, the TLP2348 is well suited to communication interfaces, programmable logic controllers (PLCs), and intelligent power module (IPM) signal isolation.
