The SN65LBC176A-EP differential bus transceiver is a monolithic, integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. The SN65LBC176A-EP is designed for balanced transmission lines and is compatible with ANSI standard TIA/EIA-485-A and ISO 8482. The SN65LBC176A-EP offers improved switching performance over its predecessors without sacrificing significantly more power.

The SN65LBC176A-EP combines a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, which can externally connect together to function as a direction control. The driver differential outputs and the 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 whenever the driver is disabled or V_CC = 0. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications. Low device supply current can be achieved by disabling the driver and the receiver.

Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits. Signaling rate by TIA/EIA-485-A definition restrict transition times to 30% of the bit length, and much higher signaling rates may be achieved without this requirement as displayed in the TYPICAL CHARACTERISTICS of this device.
