The Toshiba TLP2366(TPL,E is a single-channel, 20MBd digital optocoupler with a push-pull, totem-pole output stage and 3750Vrms isolation. The 20MBd data rate positions it for high-speed isolated communication links — think industrial fieldbus interfaces (RS-485, CAN, SPI isolators), motor-drive feedback paths, and isolated power-supply telemetry where you need to move data across a galvanic barrier at several MHz.
Propagation delay and CMTI — the timing budget for noisy environments
Maximum propagation delay of 40ns (tpLH / tpHL) and matched rise/fall times of 15ns typical give a clean, symmetric timing budget for synchronous interfaces. At 20MBd, the bit period is 50ns, so the 40ns propagation delay consumes 80% of the bit window — factor that into your setup-and-hold margin when chaining multiple isolators in series.
Package and temperature grade — industrial footprint
Housed in a 6-SOIC package with 5 leads (0.179" body width, 4.55mm), this is a surface-mount part for automated assembly. The 3750Vrms isolation rating meets the basic/reinforced isolation requirements for IEC 60950-1 and IEC 62368-1 safety standards in power supplies and motor drives.
No last-time-buy window is open, and no official successor has been issued.
