ACPL-K44CT-000E数据手册Broadcom中文资料规格书

描述 Description

The ACPL-K44CT is a dual-channel, 600V CTI, high temperature, high-CMR, 1-MBd digital automotive optocoupler in an eight-lead miniature footprint specifically used in automotive applications. The ACPL-K44CT is a dual-channel equivalent of the ACPL-K43CT. Both products are available in the stretched SO-8 package outline designed to be compatible with standard surface mount process.This digital automotive optocoupler uses an insulating layer between the light emitting diode and an integrated photo detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increases the speed up to a hundred times over that of a conventional phototransistor by reducing the base-collector capacitance.Broadcom R2Coupler automotive optocoupler isolation products provide reinforced insulation and reliability that deliver safe signal isolation critical in automotive and high-temperature industrial applications.
