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
throughout the switch. When Output Enable (OE) is low, the corresponding
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,
OE should be tied to VCC through a pullup resistor.

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Operating Condition: TA = –40°C to +85°C
NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
