Low Voltage Octal Bidirectional Transceiver
74LVX245 Low Voltage Octal Bidirectional Transceiver April 1993 Revised September 2003 74LVX245 Low Voltage Octal Bidirectional Transceiver General Description Features The LVX245 contains eight non-inverting bidirectional buff-Ideal for low power/low noise 3.3V applications ers and is intended for bus-oriented applications. TheGuaranteed simultaneous switching noise level and Transmit/Receive (T/R) input determines the direction of dynamic threshold performance 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 impedance condi- tion.
