|Datasheet||Download MC34058 datasheet
The Motorola MC34058/9 Hex Transceiver is composed of six driver/receiver combinations designed to comply with the EIA485 standard. Features include threestate outputs, thermal shutdown for each driver, and current limiting in both directions. This device also complies with EIA422 and CCITT Recommendations V.11 and X.27. The devices are optimized for balanced multipoint bus transmission at rates to 20 MBPS (MC34059). The driver outputs/receiver inputs feature a wide common mode voltage range, allowing for their use in noisy environments. The current limit and thermal shutdown features protect the devices from line fault conditions. The MC34058/9 is available in a space saving mm 48 lead surface mount quad package designed for optimal heat dissipation. Meets EIA485 Standard for Party Line Operation
