74LVXC4245  
8-Bit Dual Supply Configurable Voltage Interface  
Transceiver with 3-STATE Outputs  
General Description  
The LVXC4245 is a 24-pin dual-supply, 8-bit configurable  
voltage interface transceiver suited for PCMCIA and other  
real time configurable I/O applications. The VCCA pin  
Features  
Bidirectional interface between 5V and 3V-to-5V buses  
Control inputs compatible with TTL level  
Outputs source/sink up to 24 mA  
accepts a 5V supply level. The “A” Port is a dedicated 5V  
port. The VCCB pin accepts a 3V-to-5V supply level. The  
Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
“B” Port is configured to track the VCCB 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 configure the I/O  
pins at a 3V level. This device will allow the VCCB voltage  
Implements patented EMI reduction circuitry  
Flexible VCCB operating range  
Allows B Port and VCCB to float simultaneously when OE  
is HIGH  
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  
Functionally compatible with the 74 series 245  
a
PCMCIA socket that permits PCMCIA cards to be  
inserted and removed during normal operation.
