74F2245
Octal Bidirectional Transceiver with TRI-STATE
Outputs
General Description
The ’F2245 contains eight non-inverting bidirectional buffers
with TRI-STATE outputs and is intended for bus-oriented
applications Current sinking capability is 24 mA at the A
ports and 12 mA at the B ports The TransmitReceive
(TR) input determines the direction of data flow through
the bidirectional transceiver Transmit (active HIGH) en-
ables 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
The 25X series resistors in the outputs reduce ringing and
eliminate the need for external resistors
