FEATURES

GENERAL DESCRIPTION





Low Quiescent Current: 300µA

The CBM485 is low-power transceivers for

RS-485 and RS-422 communication. IC

contains one driver and one receiver.

-7V to +12V Common-Mode Input

Voltage Range

The driver slew rates of the CBM485 is not

limited, allowing them to transmit up to 10

Mbps.

Three-State Outputs

50ns Propagation Delays, 5ns Skew

Half-Duplex Version Available

Operate from a Single 5V Supply

Allows up to 32 Transceivers on the Bus

Data rate: 10 Mbps

These transceivers draw between 120µA

and 500µA of supply current when unloaded

or fully loaded with disabled drivers. All parts

operate from a single 5V supply. Drivers are

short-circuit current limited and are protected

against excessive power dissipation by

thermal shutdown circuitry that places the

driver outputs into a high-impedance state.

The receiver input has a fail-safe feature

that guarantees a logic-high output if the

input is open circuit. The CBM485 is designed

for half-duplex applications.

Current-Limiting and Thermal Shutdown

for Driver Overload Protection

Enhanced ESD Specifications:

±15kV IEC61000-4-2 Air Discharge

±8kV IEC61000-4-2 Contact Discharge
