1 / 9 page SN74CBTLV3384 LOW VOLTAGE 10BIT FET BUS SWITCH SCDS059G − MARCH 1998 − REVISED JUNE 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 5-Ω Switch Connection Between Two Ports D Rail-to-Rail Switching on Data I/O Ports D Ioff Supports Partial-Power-Down Mode Operation D Latch-Up Performance Exceeds 250 mA Per JESD 17 D ESD Protection Exceeds JESD 22 − 2000-V Human-Body Model (A114-A) − 200-V Machine Model (A115-A) description/ordering information The SN74CBTLV3384 provides ten bits of high-speed bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as dual 5-bit bus switches with separate output-enable (OE) inputs. It can be used as two 5-bit bus switches or one 10-bit bus switch. When OE is low, the associated 5-bit bus switch is on, and A port is connected to B port. When OE is high, the switch is open, and the high-impedance state exists between the two ports. This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off. To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
