DESCRIPTION
●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.
●FEATURE
●■ 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
