74LVXC4245
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 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 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.
Features
s Bidirectional interface between 5V and 3V-to-5V buses
s Control inputs compatible with TTL level
s Outputs source/sink up to 24 mA
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Implements patented EMI reduction circuitry
s Flexible VCCB operating range
s Allows B Port and VCCB to float simultaneously when OE
is HIGH
s Functionally compatible with the 74 series 245
