Low Voltage Octal Bidirectional Transceiver
General Description
The LVX245 contains eight non-inverting bidirectional buff-
ersis intendedfor bus-oriented applications. The Transmit/
Receive (T/R) input determinesthe directionof data flow
through the bidirectional transceiver. Transmit (active-
HIGH) enables data fromA portstoB ports; Receive(ac-
tive-LOW) enables data fromB portstoA ports.The Output
Enable input, when HIGH, disables bothA andB portsby
placing themina HIGH-Z condition.
Features Idealforlow power/low noise 3.3V applications Availablein SOIC JEDEC, SOIC EIAJ and TSSOP
packages Guaranteed simultaneous switching noise leveland
dynamic threshold performance
