74FR9245
9-Bit Bidirectional Transceiver with 3-STATE Outputs
General Description
The 74FR9245 contains nine non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus-ori-
ented applications. Current sinking capability is 64 mA on
both the A and B Ports. 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; 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.
