General Description

The LVXC3245 is a 24-pin dual-supply, 8-bit configurable

voltage interface transceiver suited for PCMCIA and other

real time configurable I/O applications. The V

accepts a 3V supply level. The A Port is a dedicated 3V

port. The V

Port is configured to track the V

tively. A 5V level on the V

at a 5V level and a 3V V

3V level. The A Port should interface with a 3V host system

and the B Port to the card slots. This device will allow the

when OE is 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.
