Octal Bidirectional Transceiver with TRI-STATE
é
Outputs
General Description
The ’F245 contains eight non-inverting bidirectional buffers
with TRI-STATE outputs and is intended for bus-oriented
applications. Current sinking capability is 24 mA (20 mA Mil)
at the A ports and 64 mA (48 mA Mil) at the B ports. The
Transmit/Receive (T/R) input determines the direction of
data flow through the bidirectional transceiver. Transmit (ac-
tive 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.
