The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device can operate as a dual 12-bit bus switch or as a single 24-bit bus switch. When 1OE is low, 1A is connected to 1B. When 2OE is low, 2A is connected to 2B. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 1OE 2OE 1B1 1B2 1B3 1B4 1B5 GND 1B6 1B7 1B8 1B9 1B10 1B11 1B12 2B1 2B2 2B3 GND 2B4 2B5 2B6 2B7 2B8 2B9 2B10 2B11 2B12 NC – No internal connection ORDERING INFORMATION PACKAGE† ORDERABLE PART NUMBER Tube SN74CBTS16211DL Tape and reel SN74CBTS16211DLR TSSOP – DGG Tape and reel SN74CBTS16211DGGR CBTS16211 TVSOP – DGV Tape and reel SN74CBTS16211DGVR CYS211 TA SSOP – DL –40°C 40°C to 85°C TOP-SIDE MARKING CBTS16211 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
