Description

The 74LVXC4245 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 accepts a 5V supply level. The "A" Port is a dedicated 5V port. The VCCB pin accepts a 3V-to-5V supply level. The "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 source pin and I/O pins of the 74LVXC4245 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.
