74LVXC4245 8-Bit Dual Supply Configurable Voltage Interface Transceiver with 3-STATE Outputs February 1994 Revised October 2003 74LVXC4245 8-Bit Dual Supply Configurable Voltage Interface Transceiver with 3-STATE Outputs General Description Features The LVXC4245 is a 24-pin dual-supply, 8-bit configurableBidirectional interface between 5V and 3V-to-5V buses voltage interface transceiver suited for PCMCIA and otherControl inputs compatible with TTL level real time configurable I/O applications. The V pin CCAOutputs source/sink up to 24 mA accepts a 5V supply level. The “A” Port is a dedicated 5V Guaranteed simultaneous switching noise level and port. The V pin accepts a 3V-to-5V supply level. The CCB dynamic threshold performance “B” Port is configured to track the V supply level CCB Implements patented EMI reduction circuitry respectively. A 5V level on the V pin will configure the CC Flexible V operating range CCB I/O pins at a 5V level and a 3V V will configure the I/O CC Allows B Port and V to float simultaneously when OE pins at a 3V level. This device will allow the V voltage CCB CCB is HIGH 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 fromFunctionally compatible with the 74 series 245 a PCMCIA socket that permits PCMCIA cards to be inserted and removed during normal operation.
