HEX EIA–485 TRANSCEIVER

with THREE–STATE OUTPUTS

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.

SEMICONDUCTOR

TECHNICAL DATA

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.
