DCL540D01(T,E

Overview

The DCL540D01(T,E is a general-purpose digital isolator from Toshiba Semiconductor and Storage, utilizing magnetic coupling technology. It features four independent channels with a unidirectional data flow configuration (4:0). The device supports a maximum data rate of 150Mbps and provides 5000Vrms isolation voltage. It operates within a supply voltage range of 2.25V to 5.5V and withstands a common-mode transient immunity of 100kV/µs. Propagation delays are typically 18.3ns, with rise/fall times of 0.9ns. It is housed in a 16-SOIC package and functions between -40°C and 110°C.
