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.
