TD541S-4xH(L)x is a family of high-performance reinforced digital isolators with an integrated isolated DC-DC converter. TD541S-4xH(L)xeliminate the need for a separate, isolated power supply, which results in a small form factor, total isolation solution. The power supplyvoltageofTD541S-4xH(L)5 is 5V and its isolated power is 5V. The power supply voltage of TD541S-4xH(L)3 is 5V and its isolated power is 3.3V. TD541S-40H(L)x device has four forward and one reverse-direction channels. TD541S-41H(L)x device has three forward and one reverse-directionchannels.
TD541S-42H(L)x device has two forward and two reverse-direction channels. TD541S-43H(L)x device has one forwardandthreereverse-direction channels. TD541S-44H(L)x device has four reverse-direction channels. It has fail-safe mode option. If the input signal lost, defaultoutput is low for devices with L. If the input signal lost, default output is low for devices with H.
