SEMICONDUCTOR TECHNICAL DATA  
The 74LVXC3245 is a 24–pin dual–supply, octal configurable voltage  
interface transceiver especially well suited for PCMCIA and other real  
time configurable I/O applications. The V  
pin accepts a 3V supply  
pin accepts a 3V–to–5V  
supply level. A 5V  
CCA  
level; the A port is a dedicated 3V port. The V  
CCB  
supply level. The B port is configured to track the V  
LOW–VOLTAGE CMOS  
CCB  
pin will configure the I/O pins at a 5V level and a 3V  
level on the V  
V
CCB  
will configure the I/O pins at a 3V level. The A port interfaces with a  
CCB  
3V host system and the B port to the card slots. This device will allow the  
voltage source pin and I/O pins on the B port to float when OE is  
V
CCB  
High. This feature is necessary to buffer data to and from a PCMCIA  
socket that permits PCMCIA cards to be inserted and removed during  
normal operation. The Transmit/Receive (T/R) input determines the  
direction of data flow. Transmit (active–High) enables data from the A port  
to B port. Receive (active–Low) enables data from the B port to the A port.
