The Intersil HCTS245MS is a Radiation Hardened Non-
Inverting Octal Bidirectional Bus Transceiver, Three-State,
intended for two-way asynchronous communication between
data busses. The HCTS245MS allows data transmission
from the A bus to the B bus or from the B bus to the A bus.
The logic level at the direction input (DIR) determines the
data direction. The output enable input (OE) puts the I/O port
in the high-impedance state when high.
