DS75176B, DS75176BT www.ti.com SNLS381C – JULY 1998 – REVISED APRIL 2013 DS75176B/DS75176BT Multipoint RS-485/RS-422 Transceivers Check for Samples: DS75176B, DS75176BT FEATURES DESCRIPTION • The DS75176B is a high speed differential TRISTATE®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. 1 23 • • • • • • • • • Meets EIA Standard RS485 for Multipoint Bus Transmission and is Compatible 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 Common 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 Common Mode Range Allows the Unused Devices on the Bus to be Powered Down. 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. 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. DC specifications are guaranteed over the 0 to 70°C temperature and 4.75V to 5.25V supply voltage range. Connection and Logic Diagram Figure 1. Top View See Package Number P0008E or D0008A 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. 1 2 3 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) Addendum-Page 1 Samples PACKAGE OPTION ADDENDUM www.ti.com 19-Mar-2015 (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
