54LVXC3245  
8-Bit Dual Supply Configurable Voltage Interface  
Transceiver with TRI-STATE® Outputs  
General Description  
Features  
n Bidirectional interface between 3V and 3V-to-5V buses  
n Control inputs compatible with TTL level  
n Outputs source/sink up to 24 mA  
The LVXC3245 is a 24-pin dual-supply, 8-bit configurable  
voltage interface transceiver suited for real time configurable  
I/O applications. The VCCA pin accepts a 3V supply level.  
The A port is a dedicated 3V port. The VCCB pin accepts a  
3V-to-5V supply level. The B port is configured to track the  
n Available in Cerpack and CDIP package  
n Implements patented EMI reduction circuitry  
n Flexible VCCB operating range  
n Allows B port and VCCB to float simultaneously when OE  
is HIGH  
V
CCB supply level respectively. A 5V level on the VCC pin will  
configure the I/O pins at a 5V level and a 3V VCC will config-  
ure the I/O pins at a 3V level. This device will allow the VCCB  
voltage source pin and I/O pins on the B port to float when  
OE is HIGH. This feature is necessary to buffer data to and  
from sockets that require live insertion and removal during  
normal operation.  
n Functionally compatible with the 54 series 245
