Octal Bidirectional Transceiver with TRI-STATEÉ Outputs
General Description
The ’F245 contains eight non-inverting bidirectional buffers
with TRI-STATE outputs andis intendedfor bus-oriented
applications. Current sinking capabilityis24mA(20mAMil)theA ports and64mA(48mAMil)attheB ports.The
Transmit/Receive (T/R) input determinesthe directionof
dataflow through thebidirectional transceiver. Transmit(ac-
tive HIGH) enables data fromA portstoB ports; Receive
(active LOW) enables data fromB portstoA ports. The
Output Enable input, when HIGH, disables bothAandB
portsby placing themina HighZ condition.
Features Non-inverting buffers Bidirectional data pathA outputs sink24mA(20mAMil)B outputs sink64mA(48mAMil) Guaranteed 4000V minimum ESD protection
