74F245 Octal Bidirectional Transceiver with 3-STATE Outputs
April 1988
Revised April 1999
74F245
Octal Bidirectional Transceiver with 3-STATE Outputs
General Description
The 74F245 contains eight non-inverting bidirectional buff-
ers with 3-STATE outputs and is intended for bus-oriented
applications. Current sinking capability is 24 mA at the A
Ports and 64 mA at the B Ports. The Transmit/Receive
(T/R) input determines the direction of data flow through
the bidirectional 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.
