74LVX245

74LVX245 Low Voltage Octal Bidirectional Transceiver April 1993 Revised March 1999 74LVX245 Low Voltage Octal Bidirectional Transceiver General Description The LVX245 contains eight non-inverting bidirectional buffers and is intended for bus-oriented applications. The Transmit/Receive (T/R) input determines the direction of 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 condition. Features s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance Ordering Code Order Number 74LVX245M 74LVX245SJ 74LVX245MTC Package Number M20B M20D MTC20 Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
