54F 74F245
Octal Bidirectional Transceiver with TRI-STATE 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
Y Non-inverting buffers
Y Bidirectional data path
Y A outputs sink 24 mA (20 mA Mil)
Y B outputs sink 64 mA (48 mA Mil)
Y Guaranteed 4000V minimum ESD protection
