VHITCLCX245-2Y
This IC is a low voltage (3.3V) CMOS 8bit bidirectional transceiver. When setting the trans-
mission 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 used to switch bus of the data from CICARD.
