产品描述

The SN75ALS174A is a quadruple line driver with 3-state differential outputs. It is designed to meet the requirements of ANSI Standards EIA/TIA-422-B and RS-485. This device is optimized for balanced multipoint bus transmission at rates of up to 20 Mbit/s. Each driver features wide positive and negative common-mode output voltage ranges that make them suitable for party-line applications in noisy environments.

The SN75ALS174A provides positive- and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of approximately 150°C.

The SN75ALS174A is characterized for operation from 0°C to 70°C.

H = high level, L = low level, X = irrelevant, Z = high impedance (off)
