74F2245
Octal Bidirectional Transceiver with TRI-STATE Outputs
General Description
The 鈥橣2245 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 Transmit Receive
(T R) 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
eliminate the need for external resistors
