Микросхемы и комплектующие LTC2877CDD#PBF

Приемопередатчик , RS485, 3В-5.5В питание, 1 драйвер, DFN-10

The LTC2877CDD#PBF is a ±60V rugged PROFIBUS RS485 transceiver in 10 pin DFN package. The device is fully compatible with IEC 61158-2, type 3, medium attachment unit (MAU). The LTC2877 supports all PROFIBUS data rates up to 12Mbps with operation up to 20Mbps. It is exceptionally robust, tolerating ±60V faults on the bus pins and protected to ±52KV ESD. This device is suitable for harsh environments or where 24V power might be inadvertently connected. Extended ±25V input common mode range and full fail-safe operation improve data communication reliability in noisy systems. The LTC2877 meets PROFIBUS and RS485 specifications. It has fully balanced differential receiver thresholds with 240mV hysteresis for superior noise tolerance and low duty cycle distortion. It is typically used in RS485 systems, RS422 systems and 3V low voltage differential signalling applications.
