SN65HVD11HD

产品概述

The SN65HVD11HD is a RS-485 High-temperature Transceiver for use with down-hole drilling. The device combines a 3-state differential line driver and differential input line receiver that operates with a single 3.3V power supply. It is designed for balanced transmission lines and meets or exceeds ANSI TIA/EIA-485-A and ISO 8482:1993, with the exception that the thermal shutdown is removed. This differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. The driver and receiver have active-high and active-low enables, respectively, that can be externally connected together to function as direction control. The driver differential outputs and receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC=0.

• Open-circuit, idle-bus and shorted-bus failsafe receiver
• Glitch-free power-up and power-down protection for hot-plugging applications
• Bus-pin ESD protection exceeds 16kV human-body model (HBM)
• Bus-pin short-circuit protection from -7 to 12V
• Green product and no Sb/Br
