SN75ALS175数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

The SN75ALS175 is a monolithic quadruple differential line receiver with 3-state outputs. It is designed to meet the requirements of ANSI Standards EIA/TIA-422-B, EIA/TIA-423-B, and RS-485 and several ITU recommendations. Advanced low-power Schottky technology provides high speed without the usual power penalty. Each of the two pairs of receivers has a common active-high enable. The device features high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range of -12 V to 12 V. The SN75ALS175 is characterized for operation from 0°C to 70°C. H = high level, L = low level, ? = indeterminate,X = irrelevant, Z = high impedance (off)
