FUNCTIONAL BLOCK DIAGRAM
LOW-VOLTAGE 20-BIT
BUS SWITCH
DESCRIPTION:The CBTLV16210 operates as a single 20-bit bus switch or as a dua
10-bit bus switch,which provides high-speed switching. This device has
very low ON resistance, resulting in under 250ps propagation delay
through the switch. When Output Enable (OE) is low, the corresponding
10-bit bus switch is on and port A is connected to Port B. WhenOE 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 VCCthrough a pullup resistor.

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGEFollowing Conditions Apply Unless Otherwise Specified:
Operating Condition: T A= –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.

(zero output impededance).
