SN75ALS172AN
SN75ALS172AN is QUADRUPLE DIFFERENTIAL LINE DRIVER manufactured by Texas Instruments.
- Part of the SN75ALS172A comparator family.
- Part of the SN75ALS172A comparator family.
description
The SN75ALS172A prises four line drivers with 3-state differential outputs. They are designed to meet the requirements of ANSI Standards EIA/TIA-422-B and RS-485 and ITU Remendation V.11. This device is optimized for balanced multipoint bus transmission at rates of up to 20 Mbaud. Each driver features wide positive and negative mon-mode output voltage ranges, making it suitable for party-line applications in noisy environments.
