Product Description
Product Overview
The Broadcom ACPL-K43T and ACPL-K44T are high-temperature, high-CMR, high-speed digital optocouplers designed for automotive applications. These devices utilize an insulating layer between the LED and photo detector for electrical isolation. Separate connections for photodiode bias and output transistor collector enhance speed by reducing base-collector capacitance. Broadcom R2Coupler isolation products offer reinforced insulation and reliability, crucial for automotive and high-temperature industrial environments. They are available in a compact, auto-insertable stretched SO-8 package compatible with standard surface-mount processes.Product Attributes
