Configurable Dual Supply
Octal Transceiver
with 3State Outputs for 3 V Systems
The 74LVXC3245 is a 24pin dualsupply, octal configurable
voltage interface transceiver especially well suited for PCMCIA and
other real time configurable I/O applications. The V
CCA
pin accepts a
3.0 V supply level; the A port is a dedicated 3.0 V port. The V
CCB
pin
accepts a 3.0 Vto5.0 V supply level. The B port is configured to
track the V
CCB
supply level. A 5.0 V level on the V
CCB
pin will
configure the I/O pins at a 5.0 V level and a 3.0 V V
CCB
will configure
the I/O pins at a 3.0 V level. The A port interfaces with a 3.0 V host
system and the B port to the card slots. This device will allow the
V
CCB
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 (activeHigh) enables data from the A
port to B port. Receive (activeLow) enables data from the B port to
the A port.
Features
Bidirectional Interface Between 3.0 V and 3.0 V/5.0 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 V
CCB
Operating Range
Allows B Port and V
CCB
to Float Simultaneously When OE is High
Functionally Compatible With the 74 Series 245
