SN75ALS176P .

产品概述

The SN75ALS176P is a differential Bus Transceiver is designed for bidirectional data communication on multipoint bus transmission lines. For balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A and ITU recommendations V.11 and X.27. The SN75ALS176 series combine a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally to function as a direction control. The driver differential outputs and the receiver differential inputs are connected 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. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications.

• Operate at data rates up to 35Mbaud
• Designed for multipoint transmission on long bus lines in noisy environments
• Wide positive and negative input or output bus-voltage range
• Thermal shutdown protection
• Driver positive and negative current limiting
• Receiver input hysteresis
• Glitch-free power-up and power-down protection
• Receiver has open-circuit, fail-safe design
