74F245 Rev. 1.4.0
January 2008
74F245
Octal Bidirectional Transceiver with 3-STATE Outputs
Features
■
Non-inverting buffers
■
Bidirectional data path
■
A outputs sink 24mA
■
B outputs sink 64mA
General Description
The 74F245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus-
oriented applications. Current sinking capability is
24mA at the A Ports and 64mA at the B Ports. The
Transmit/Receive (T/R
) input determines the direction
of data flow through the bidirectional transceiver. Trans-
mit (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.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.
