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.

• Meets EIA–485 Standard for Party Line Operation

• Meets EIA–422A and CCITT Recommendations V.11 and X.27

• Operating Ambient Temperature: 0°C to +70°C

• Common Mode Driver Output/Receiver Input Range: –7.0 to +12 V

• Positive and Negative Current Limiting

• Transmission Rates to 14 MBPS (MC34058) and 20 MBPS (MC34059)

• Driver Thermal Shutdown at 150°C Junction Temperature

• Thermal Shutdown Active Low Output

• Single +5.0 V Supply, ±10%

• Low Supply Current

• Compact 7.0 mm 48 Lead TQFP Plastic Package
