Configurable Dual Supply
Octal Transceiver

voltage interface transceiver especially well suited for PCMCIA and
other real time configurable I/O applications. The V
3.0 V supply level; the A port is a dedicated 3.0 V port. The V
accepts a 3.0 V−to−5.0 V supply level. The B port is configured to
track the V
configure the I/O pins at a 5.0 V level and a 3.0 V V
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
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.
