DESCRIPTION
The P54/74FCT245 contains eight non-inverting bidirec-
tional buffers with 3-state outputs and is intended for bus
oriented applications. The transmit/receive (T/R) input
determines the direction of data flow through the bidirec-
tional transceiver. Transmit (active HIGH) enables data
from A ports to B ports, and receive (active LOW) from
B ports to A ports. The output enable (OE) input, when
HIGH, disables both A and B ports by placing them in a
High-Z condition.

Notes:
1. Operation beyond the limits set forth in the above table may impair
the useful life of the device. Unless otherwise noted, these limits are
over the operating free-air temperature range.
2. Unused inputs must always be connected to an appropriate logic
voltage level, preferably either VCC or ground.
