Part Details:

74L February 1994 VXC324 Revised October 2003 5 8- 74LVXC3245 Bit 8-Bit Dual Supply Configurable Voltage Interface Dual Transceiver with 3-STATE Outputs General Description Features Supp The LVXC3245 is a 24-pin dual-supply, 8-bit configurable s Bidirectional interface between 3V 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 3V supply level. The A Port is a dedicated 3V s Guaranteed simultaneous switching noise level and Confi port. The VCCB pin accepts a 3V-to-5V supply level. The B dynamic threshold performance Port is configured to track the VCCB supply level respec- s Implements patented EMI reduction circuitry tively. A 5V level on the VCC pin will configure the I/O pins s Flexible V gurabl at a 5V level and a 3V V CCB operating range CC will configure the I/O pins at a 3V level. The A Port should interface with a 3V host system s Allows B Port and VCCB to float simultaneously when OE and the B Port to the card slots. This device will allow the is HIGH VCCB voltage source pin and I/O pins on the B Port to float s Functionally compatible with the 74 series 245 e when OE is HIGH. This feature is necessary to buffer data V to and from a PCMCIA socket that permits PCMCIA cards ol to be inserted and removed during normal operation. ta ge I Ordering Code: nter Order Number Package Number Package Description fac
