LTC1485IN8 Datasheet

Differential Bus Transceiver


The LTC® 1485 is a low power differential bus/line transceiver designed for multipoint data transmission standard RS485 applications with extended common-mode range (12V to – 7V). It also meets the requirements of RS422.
The CMOS with Schottky design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage.

■ ESD Protection over ±10kV
■ Low Power: ICC= 1.8mA Typ
■ 28ns Typical Driver Propagation Delays with 4ns Skew
■ Designed for RS485 or RS422 Applications
■ Single 5V Supply
■ – 7V to 12V Bus Common-Mode Range Permits ±7V Ground Difference Between Devices on the Bus
■ Thermal Shutdown Protection
■ Power-Up/Down Glitch-Free Driver Outputs
■ Driver Maintains High Impedance in Three-State or with the Power Off
■ Combined Impedance of a Driver Output and Receiver Allows up to 32 Transceivers on the Bus
■ 60mV Typical Input Hysteresis
■ Pin Compatible with the SN75176A, DS75176A, and SN75LBC176
