HCPL261A中文资料安捷伦数据手册PDF规格书

描述 Description

The HCPL-261A family of optically coupled gates shown on this data sheet provide all the benefits of the industry standard 6N137 family with the added benefit of HCMOS compatible input current. This allows direct interface to all common circuit topologies without additional LED buffer or drive components. The AlGaAs LED used allows lower drive currents and reduces degradation by using the latest LED technology. On the single channel parts, an enable output allows the detector to be strobed. The output of the detector IC is an open collector schottky clamped transistor. The internal shield provides a minimum common mode transient immunity of 1000 V/µs for the HCPL-261A family and 15000 V/µs for the HCPL-261N family.
