SN74CBT3861 10-BIT FET BUS SWITCH SCDS061D – APRIL 1998 – REVISED OCTOBER 2000 D D D DBQ, DGV, DW, OR PW PACKAGE (TOP VIEW) 5-Ω Switch Connection Between Two Ports TTL-Compatible Input Levels Latch-Up Performance Exceeds 250 mA Per JESD 17 NC A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 GND description The SN74CBT3861 provides ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one 10-bit switch with a single output-enable (OE) input. When OE is low, the switch is on, and port A is connected to port B. When OE is high, the switch is open, and the high-impedance state exists between the two ports. 1 24 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 12 13 VCC OE B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 NC – No internal connection ORDERING INFORMATION TOP-SIDE MARKING Tube SN74CBT3861DW Tape and reel SN74CBT3861DWR SSOP (QSOP) – DBQ Tape and reel SN74CBT3861DBQR CBT3861 TSSOP – PW Tape and reel SN74CBT3861PWR CU861 TVSOP – DGV Tape and reel SN74CBT3861DGVR SOIC – DW –40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA CBT3861 CU861 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
