LTC2877HMSE#PBF

LTC2877HMSE#PBF is a PROFIBUS RS485 transceiver that is designed to meet the test specifications for PROFIBUS-DP hosts and PROFIBUS-DP servers, fully compatible with IEC 61158-2, type 3: medium attachment unit (MAU). With operation up to 20Mbps, this device supports all PROFIBUS data rates upto 12Mbps. 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 failsafe operation improve data communication reliability in noisy systems. It is used in applications such as PROFIBUS-DP, industrial communication networks, RS485 and RS422 systems, 3V low voltage differential signaling.

• Supply voltage range from 4.5V to 5.5V, logic supply pin
• 5V supply can operate down to 3V for low power, low swing applications
• Receiver failsafe for open, shorted and terminated conditions
• Supply current in shutdown mode is 5µA maximum at (TA = 25°C. VCC = VL = 5V)
• Input resistance (receiver) is 112Kohm typical at (VBUS = -25V or 25V)
• Driver rise or fall time is 4ns typical at (VCC = 3.3V or 5V)
• Differential input failsafe hysteresis (receiver) is 45mV typical at (TA = 25°C)
• Receiver short-circuit current is ±12mA typical at (TA = 25°C. VCC = VL = 5V)
• Operating temperature range from -40°C to 125°C
• 10-lead plastic MSOP package
