1 / 12 page SN74CBTLV16211 LOW VOLTAGE 24BIT FET BUS SWITCH SCDS043I − DECEMBER 1997 − REVISED OCTOBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Member of the Texas Instruments Widebus Family 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 SN74CBTLV16211 provides 24 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 12-bit bus switches with separate output-enable (OE) inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE is low, the associated 12-bit bus 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. 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 should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
