LOW-VOLTAGE 10-BIT
IDT74CBTLV3862
BUS SWITCH WITH ACTIVE
HIGH AND LOW ENABLES
FEATURES:
DESCRIPTION:
• 5Ω A/B bi-directional switch
TheCBTLV3862providestenbitsofhigh-speedbusswitchingwithlow
on-state resistance of the switch allowing connections to be made with
minimalpropagationdelay.
• Isolation Under Power-Off Conditions
• Over-voltage tolerant
• Latch-up performance exceeds 100mA
• VCC = 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
The device is organized as one 10-bit bus switch. The switches are
controlled by independent active-low enable (OE) and active-high enable
(OE) controls.
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
theresistorisdeterminedbythecurrent-sinkingcapabilityofthedriver,and
OE should be tied to GND.
APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation

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 rating
conditions for extended periods may affect reliability.

NOTES:
1. Typical Values are at VCC = 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.

NOTE:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance when driven by an ideal voltage source
(zero output impededance).
