1 / 4 page SN74CBT3345 8-BIT FET BUS SWITCH SCDS027D – MAY 1995 – REVISED MAY 1998 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Standard ’245-Type Pinout D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels D Package Options Include Plastic Shrink Small-Outline (DB), Thin Very Small-Outline (DGV), Small-Outline (DW), and Thin Shrink Small-Outline (PW) Packages description The SN74CBT3345 provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one 8-bit switch bank with dual output-enable (OE and OE) inputs. When OE is low or OE is high, the switch is on and port A is connected to port B. When OE is high and OE is low, the switch is open and a high-impedance state exists between the two ports. The SN74CBT3345 is characterized for operation from 0 °C to 70°C.
