UC5180C Octal Line Receiver FEATURES DESCRIPTION • Meets EIA 232E/423A/422A and CCITT V.10,V.11, V.28, X.26, X.27 • Single +5V Supply--TTL Compatible Outputs • Differential Inputs Withstand ± 25V • Low Open Circuit Voltage for Improved Failsafe Characteristic The UC5180C is an octal line receiver designed to meet a wide range of digital communications requirements as outlined in EIA standards EIA232E, EIA423A, EIA422A, and CCITT V.10, V.11, V.28, X.26, and X.27. The UC5180C includes an input noise filter and is intended for applications employing data rates up to 200 KBPS. A failsafe function allows these devices to "fail" to a known state under a wide variety of fault conditions at the inputs. • Reduced Supply Current--35 mA Max • Input Noise Filter • Internal Hysteresis ABSOLUTE MAXIMUM RATINGS (Note 1) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Output Sink Current. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50 mA Output Short Circuit Time . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Sec Common Mode Input Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Differential Input Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Failsafe Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 to VCC PLCC Power Dissipation, TA = 25°C (Note 2). . . . . . . . . . . . . . . . . . . 1000 mW DIP Power Dissipation, TA = 25°C (Note 2) . . . . . . . . . . . . . . . . . . . . 1200 mW Storage Temperature Range. . . . . . . . . . . . . . . . . . . . . . . . . . -65°C to +150°C Lead Temperature (Soldering, 10 Seconds) . . . . . . . . . . . . . . . . . . . . . . -300°C Note 1: All voltages are with respect to ground, pin 14.

AC Test Circuit APPLICATIONS INFORMATION under fault conditions, while a connection to ground provides a logic "0". There are two failsafe pins (FS1 and FS2) on the UC5180C where each provides common failsafe control for four receivers. Failsafe Operation These devices provide a failsafe operating mode to guard against input fault conditions as defined in EIA422A and EIA423A standards. These fault conditions are (1) drive in power-off condition, (2) receiver not interconnected with driver, (3) open-circuited interconnecting cable, and (4) short-circuited interconnecting cable. If one of these four fault conditions occurs at the inputs of a receiver, then the output of that receiver is driven to a known logic level. The receiver is programmed by connecting the failsafe input to VCC or ground. A connection to VCC provides a logic "1" output Input Filtering (UC5180C) The UC5180C has input filtering for additional noise rejection. This filtering is a function of both signal level and frequency. For the specified input (5.5 MHz at ±500 mV) the input stage filter attenuates the signal such that the output stage threshold levels are not exceeded and no change of state occurs at the output.

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) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
