FEATURES - 23 Meets EIA Standard RS485 for Multipoint Bus Transmission and is patible with RS-422. - Small Outline (SOIC) Package Option Available for Minimum Board Space. - 22 ns Driver Propagation Delays. - Single +5V Supply. - - 7V to +12V Bus mon Mode Range Permits ±7V Ground Difference Between Devices on the Bus. - Thermal Shutdown Protection. - High Impedance to Bus with Driver in TRISTATE or with Power Off, Over the Entire mon Mode Range Allows the Unused Devices on the Bus to be Powered Down. - bined Impedance of a Driver Output and Receiver Input is Less Than One RS485 Unit Load, Allowing up to 32 Transceivers on the Bus. - 70 m V Typical Receiver Hysteresis. Connection and Logic Diagram DESCRIPTION The SN75176B / SN65176B is a high speed differential TRI-STATE®bus/line transceiver designed to meet the requirements of EIA standard RS485 with extended mon mode range (+12V to - 7V), for multipoint data transmission. In addition, it is patible with RS-422. The driver and receiver outputs feature TRI-STATE capability, for the driver outputs over the entire mon 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. DC specifications are guaranteed over the 0 to 70°C temperature and 4.75V to 5.25V supply voltage range. Figure 1. Top View 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. .umw-ic. 友台半导体有限公司 UMW R SN75176B/ SN65176B Absolute Maximum Ratings (1)(2) Supply Voltage, VCC Control Input Voltages Driver Input Voltage Driver Output Voltages Receiver Input Voltages Receiver Output Voltage Continuous Power Dissipation @ 25°C for SOIC Package for PDIP Package Storage Temperature Range Lead Temperature (Soldering, 4...
