Part Details:

74L February 1994 VXC424 Revised October 2003 5 8- 74LVXC4245 Bit 8-Bit Dual Supply Configurable Voltage Interface Dual Transceiver with 3-STATE Outputs General Description Features Supp The LVXC4245 is a 24-pin dual-supply, 8-bit configurable s Bidirectional interface between 5V and 3V-to-5V buses voltage interface transceiver suited for PCMCIA and other s Control inputs compatible with TTL level real time configurable I/O applications. The VCCA pin s ly Outputs source/sink up to 24 mA accepts a 5V supply level. The "A" Port is a dedicated 5V s Guaranteed simultaneous switching noise level and Confi port. The VCCB pin accepts a 3V-to-5V supply level. The dynamic threshold performance "B" Port is configured to track the VCCB supply level s Implements patented EMI reduction circuitry respectively. A 5V level on the VCC pin will configure the s Flexible V gurabl I/O pins at a 5V level and a 3V V CCB operating range CC will configure the I/O pins at a 3V level. This device will allow the V s Allows B Port and V CCB voltage CCB to float simultaneously when OE source pin and I/O pins on the "B" Port to float when OE is is HIGH HIGH. This feature is necessary to buffer data to and from s Functionally compatible with the 74 series 245 e a PCMCIA socket that permits PCMCIA cards to be V inserted and removed during normal operation. ol tage I Ordering Code: n Order Number Package Number Package Description ter
