DS75176B/DS75176BT Multipoint RS-485/RS-422 Transceivers

Check for Samples: DS75176B, DS75176BT

FEATURES

DESCRIPTION

The DS75176B is a high speed differential TRI-

•

Meets EIA Standard RS485 for Multipoint Bus

Transmission and is Compatible with RS-422.

STATE^®bus/line transceiver designed to meet the

requirements of EIA standard RS485 with extended

common mode range (+12V to −7V), for multipoint

data transmission. In addition, it is compatible with

RS-422.

•

Small Outline (SOIC) Package Option Available

for Minimum Board Space.

•

22 ns Driver Propagation Delays.

Single +5V Supply.

The driver and receiver outputs feature TRI-STATE

capability, for the driver outputs over the entire

common mode range of +12V to −7V. Bus contention

or fault situations that cause excessive power

dissipation within the device are handled by a thermal

shutdown circuit, which forces the driver outputs into

the high impedance state.

−7V to +12V Bus Common Mode Range

Permits ±7V Ground Difference Between

Devices on the Bus.

•

Thermal Shutdown Protection.

High Impedance to Bus with Driver in TRI-

STATE or with Power Off, Over the Entire

Common Mode Range Allows the Unused

Devices on the Bus to be Powered Down.

DC specifications are guaranteed over the 0 to 70°C

temperature and 4.75V to 5.25V supply voltage

range.

•

Pin Out Compatible with DS3695/A and

SN75176A/B.

Combined Impedance of a Driver Output and

Receiver Input is Less Than One RS485 Unit

Load, Allowing up to 32 Transceivers on the

Bus.

•

70 mV Typical Receiver Hysteresis.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
