 SCDS068C – JULY 1998 – REVISED OCTOBER 2000SN74CBT1686120-BIT FET BUS SWITCH DMember of Texas Instruments’ Widebus™DDDFamily5-Ω Switch Connection Between Two PortsTTL-Compatible Input LevelsLatch-Up Performance Exceeds 100 mA PerJESD 78, Class IIDGG, DGV, OR DL PACKAGE(TOP VIEW)descriptionThe SN74CBT16861 provides 20 bits ofhigh-speed TTL-compatible bus switching. Thelow on-state resistance of the switch allowsconnections to be made with minimal propagationdelay.The device is organized as one dual 10-bit switchwith separate output-enable (OE) input. When OEis low, the switch is on, and port A is connected toport B. When OE is high, the switch is open, andthe high-impedance state exists between the twoports.NC1A11A21A31A41A51A61A71A81A91A10GNDNC2A12A22A32A42A52A62A72A82A92A10GND123456710111213141516171819202122232448474443424140393837363534333231302928272625VCC1OE1B11B21B31B41B51B61B71B81B91B10VCC2OE2B12B22B32B42B52B62B72B82B92B10NC – No internal connectionORDERING INFORMATIONTAPACKAGE†SSOPDLSSOP – DL–4040°CC to 85to85°CTSSOP – DGGTVSOP – DGVTubeTape and reelTape and reelTape and reelORDERABLEPART NUMBERSN74CBT16861DLSN74CBT16861DLRSN74CBT16861DGGRSN74CBT16861DGVRTOP-SIDEMARKINGCBT16861CBT16861CY861†Package drawings, standard packing quantities, thermal data, symbolization, and PCB designguidelines are available at www.ti.com/sc/package.FUNCTION TABLE(each 10-bit bus switch)INPUTOELHFUNCTIONA port = B portDisconnectPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.Widebus is a trademark of Texas Instruments.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
