LOW-VOLTAGE OCTAL  
BUS SWITCH  
IDT74CBTLV3245  
FEATURES:  
DESCRIPTION:  
• Pin-out compatible with standard '245 Logic products  
• 5Ω A/B bi-directional switch  
The octal bus switch has standard 245 pinouts. The CBTLV3245 is  
designed for asynchronous communication between data buses. When  
OutputEnable(OE)islow,the8-bitbusswitchisonandportAisconnected  
to Port B. When OE is high, the switch is off and a high impedance exists  
between Port A and Port B.  
• 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 QSOP and TSSOP packages  
To ensure the high-impedance state during power up or power down,  
OE should be tied to VCC through a pullup resistor.  
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 current 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.
