HCPL-263N中文资料安华高数据手册PDF规格书

Description

The HCPL-2602/12 are optically coupled line receivers that combine a GaAsP light emitting diode, an input current regulator and an integrated high gain photo detector. The input regulator serves as a line termination for line receiver applications. It clamps the line voltage and regulates the LED current so line reflections do not interfere with circuit performance.

Features

• 1000 V/µs minimum Common Mode Rejection (CMR) at

VCM = 50 V for HCPL-2602 and 3.5 kV/µs minimum

CMR at VCM = 300 V for HCPL-2612
