= 2.3V - 3.6V, Normal Range
ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
Available in SSOP, QSOP, and TSSOP packages
DESCRIPTION:
The CBTLV3861 provides ten bits of high-speed bus switching with
low on-state resistance of the switch allowing connections to be made
with minimal propagation delay.
The device is organized as one 10-bit bus switch. When output
enable (OE) is low, the 10-bit bus switch is on and port A is connected
to port B. When
OE
is high, the switch is open and a high-impedance
state exists between the two ports.
To ensure the high-impedance state during power up or power down,
OE
should be tied to V
CC
through a pullup resistor; the minimum value
of the resistor is determined by the current-sinking capability of the
driver.
APPLICATIONS:
–
3.3V High Speed Bus Switching and Bus Isolation

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum

NOTES:
1. Typical values are at V
CC
= 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 V
CC
or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
