IDT74CBTLV3384
LOW-VOLTAGE 10-BIT
BUS SWITCH
FEATURES:
DESCRIPTION:
• 5Ω A/B bi-directional bus switch
• Isolation under power-off conditions
• Over-voltage tolerant
The CBTLV3384 is a ten bit high-speed bus switch with low on-state
resistance of the switch allowing connections to be made with minimal
propagation delay.
• 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 QSOP and TSSOP packages
Thedeviceisorganizedasdual5-bitbusswitcheswithseparateoutput-
enable(OE)inputs, toallowuseastwo5-bitbusswitchesorone10-bitbus
switch. When OE is low, the associated 5-bit bus switch is on and A port is
connected to B port. 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 VCC 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 rating
conditions for extended periods may affect reliability.

NOTES:
1. The increase in supply current is attributable to each current that is at the specified voltage level rather than VCC or GND.
2. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages
of the two (A or B ) terminals.
