MC74LVXC3245
Configurable Dual Supply
Octal Transceiver
with 3–State Outputs for 3 V Systems
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
3 V supply level; the A port is a dedicated 3 V port. The VCCB pin
accepts a 3 V–to–5 V supply level. The B port is configured to track
the VCCB supply level. A 5 V level on the VCCB pin will configure the
I/O pins at a 5 V level and a 3 V VCCB will configure the I/O pins at a
3 V level. The A port interfaces with a 3 V 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 3 V and 3 V/5 V Buses
Control Inputs Compatible with TTL Level
Outputs Source/Sink Up to 24 mA
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
