VHiTCLCX245-2Y
This IC is a low voltage (3.3V) CMOS 8bit bidirectional transceiver. When setting the
transmission direction change input DIR to “H”, the A bus is switched to input and the
B bus is changed to output; if the DIR is set to “L”, the B bus is switched to input and
the A bus is changed to output. When setting the enable input OE to “H”, both A and
B buses enter the high impedance state. In this equipment, it is used to switch bus of
the data from CI-CARD.
