General Description
The ’AC’ACT245 contains eight non-inverting bidirectional
buffers with TRI-STATE outputs and is intended for bus-ori-
ented applications Current sinking capability is 24 mA at
both the A and B ports The TransmitReceive (TR) input
determines the direction of data flow through the bidirec-
tional transceiver
Transmit (active-HIGH) enables data
from A ports to B ports Receive (active-LOW) enables data
from B ports to A ports The Output Enable input when
HIGH disables both A and B ports by placing them in a
HIGH Z condition
