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 V

accepts a 5V supply level. The “A” Port is a dedicated 5V

port. The V

“B” Port is configured to track the V

respectively. A 5V level on the V

I/O pins at a 5V level and a 3V V

pins at a 3V level. This device will allow the V

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

a PCMCIA socket that permits PCMCIA cards to be

inserted and removed during normal operation.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
