74LVXC3245
8-Bit Dual Supply Configurable Voltage Interface
Transceiver with 3-STATE Outputs
Features
■ Bidirectional interface between 3V and 3V-to-5V buses
■ Control inputs compatible with TTL level
■ Outputs source/sink up to 24 mA
■ Guaranteed simultaneous switching noise level and
dynamic threshold performance
■ Flexible VCCB operating range
■ Allows B Port and VCCB to float simultaneously when OE
is HIGH
■ Functionally compatible with the 74 series 245
General Description
The LVXC3245 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 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 respec-
tively. 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. The A Port should interface 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.
