Цифровые изоляторы ISO7741FDW

Цифровой изолятор , 4 канала, 10.7 нс, 2.25 В, 5.5 В, WSOIC, 16 вывод(-ов)

The ISO7741FDW is a high speed, robust EMC reinforced quad-channel digital isolator is 16 pin SOIC package. It 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 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. It has three forward and one reverse direction channels. Used in conjunction with isolated power supplies, this device helps prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. It has enhanced to ease system-level ESD, EFT, surge and emissions compliance. It has 5000VRMS isolation ratings per UL 1577 and reinforced insulation ratings according to VDE, CSA, TUV and CQC.

Области применения

Связь и Сеть, Привод Двигателя и Управление, Управление Питанием, Промышленное, Автоматизация и Управление Процессами This device has limited built-in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
