FUNCTIONAL BLOCK DIAGRAM

LOW-VOLTAGE 24-BIT

BUS SWITCH

DESCRIPTION:

The CBTLV16211 operates as a single 24-bit bus switch or as a dual

12-bit bus switch, which provides high speed switching. This device has

very low ON resistance, resulting in under 250ps propagation delay

throughouttheswitch. WhenOutputEnable(OE)islow,thecorresponding

12-bit bus switch is on and port A is connected to Port B. When OE is high,

the switch is off and a high impedance exists between Port A and Port B.

To ensure the high-impedance state during power up or power down,
