ISO7731DWR General Description

The ISO773x devices are high-performance, triple-channel digital isolators with 5000 V_RMS (DW package) and 3000 V_RMS (DBQ package) isolation ratings per UL 1577.

This family includes devices with reinforced insulation ratings according to VDE, CSA, TUV and CQC. The ISO7731B device is designed for applications that require basic insulation ratings only.

The ISO773x family of devices provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO₂) insulation barrier. This device comes with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption.

Working well. Surprisingly loud for small size.

G**n 02/21/2021

Bought for dad, said good, but in the case have not yet tried. The order came faster than ordered in other stores before this order.

P**a 07/06/2020

The store is excellent, the goods of good quality are not the first time i order. I recommend to buy.

N**s 01/21/2020

Delivery-6.5 days. Diodes are bright. Pay attention to the size of these diodes. They are square 3,5x3.5mm. Do not confuse with diodes 3528. Substrate "minus" wide.
