MOTOROLA ANALOG IC DEVICE DATA
The Motorola MC34058/9 Hex Transceiver is composed of six
driver/receiver combinations designed to comply with the EIA–485 standard.
Features include three–state outputs, thermal shutdown for each driver, and
current limiting in both directions. This device also complies with EIA–422
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 7.0 mm 48 lead surface
mount quad package designed for optimal heat dissipation.
