74CBTLV3384
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

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
