The SN65LBC180DR is a low-power differential Line Driver and Receiver designed for bidirectional data communication over long cables that take on the characteristics of transmission lines. It is balanced or differential, voltage mode devices that meet or exceed the requirements of industry standard ANSI RS-485 and ISO 8482:1987(E). This device is designed using TIs proprietary LinBiCMOS? with the low-power consumption of CMOS and the precision and robustness of bipolar transistors in the same circuit. It combines a differential line driver and receiver with 3-state outputs and operate from a single 5V supply. The driver and receiver have active-high and active-low enables, respectively, which can be externally connected to function as a direction control. The driver differential outputs and the receiver differential inputs are connected to separate terminals for full-duplex operation and are designed to present minimum loading to the bus whether disabled or powered off (VCC=0).
Thermal shutdown protection prevents driver damage from bus contention
Positive and negative output current limiting
Pin-compatible with the SN75ALS180
Designed for high-speed multipoint data transmission over long cables
