HCPL-261A
所属分类
光耦合器
目标应用
6N137光耦合器低输入电流(3.0毫安)HCMOS兼容版本隔离线接收器单面/多路数据传输计算机外围设备接口数字隔离模/数转换,模数转换开关电源仪表输入/输出隔离消除接地环路脉冲变压器置换

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.

HCMOS/LSTTL/TTL performance compatible
1000 V/μs minimum Common Mode Rejection (CMR) at VCM = 50 V (HCPL-261A family) and 15 kV/μs minimum CMR at VCM = 1000 V (HCPL-261N family)
High speed: 10 MBd typical
AC and DC performance specified over industrial temperature range -40°C to +85°C
Available in 8 pin DIP, SOIC-8 packages
Safety approval:
   [1]UL recognized per UL1577 3750 V rms for 1 minute and 5000 V rms for 1 minute (Option 020)
   [2]CSA Approved
   [3]IEC/EN/DIN EN 60747-5-2 approved
