1 / 9 page SN74CBTH16211 24-BIT FET BUS SWITCH WITH BUS HOLD SCDS062C – JUNE 1998 – REVISED NOVEMBER 2001 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels D Bus Hold on Data Inputs/Outputs Eliminates the Need for External Pullup/Pulldown Resistors description The SN74CBTH16211 provides 24 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 dual 12-bit bus switches with separate output-enable (OE) inputs. It can be used as two 12-bit bus switches or one 24-bit bus switch. When OE is low, the associated 12-bit bus switch is on, and the A port is connected to the B port. When OE is high, the switch is open, and a high-impedance state exists between the two ports. Active bus-hold circuitry is provided to hold unused or floating A and B ports at a valid logic level. 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.
