The 74LVXC3245 is a 24–pin dual–supply, octal configurable voltage
interface transceiver especially well suited for PCMCIA and other real
time configurable I/O applications. The VCCA pin accepts a 3V supply
level; the A port is a dedicated 3V port. The VCCB pin accepts a 3V–to–5V
supply level. The B port is configured to track the VCCB supply level. A 5V
level on the VCCB pin will configure the I/O pins at a 5V level and a 3V
VCCB will configure the I/O pins at a 3V level. The A port interfaces with a
3V host system and the B port to the card slots. 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. The Transmit/Receive (T/R) input determines the
direction of data flow. Transmit (active–High) enables data from the A port
to B port. Receive (active–Low) enables data from the B port to the A port.
Bidirectional Interface Between 3V and 3V/5V Buses
Control Inputs Compatible with TTL Level
Outputs Source/Sink Up to 24mA
Guaranteed Simultaneous Switching Noise Level and Dynamic
Threshold Performance
Available in SOIC and TSSOP Packages
Flexible VCCB Operating Range
Allows B Port and VCCB to Float Simultaneously When OE Is High
Functionally Compatible with the 74 Series 245
