74LVX245 Low Voltage Octal Bidirectional Transceiver April 1993 Revised March 1999 74LVX245 Low Voltage Octal Bidirectional Transceiver General Description A and B Ports by placing them in a high impedance condi- tion. The LVX245 contains eight non-inverting bidirectional buff- ers and is intended for bus-oriented applications. The Transmit/Receive (T/R) input determines the direction of Features data flow through the bidirectional transceiver. Transmit s Ideal for low power/low noise 3.3V applications (active-HIGH) enables data from A Ports to B Ports; s Guaranteed simultaneous switching noise level and Receive (active-LOW) enables data from B Ports to A dynamic threshold performance Ports. The Output Enable input, when HIGH, disables both Ordering Code Order Number Package Number Package Description 74LVX245M M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 74LVX245SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74LVX245MTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
