74VCXH245 Low Voltage Bidirectional Transceiver with Bushold June 1999 Revised April 2005 74VCXH245 Low Voltage Bidirectional Transceiver with Bushold General Description The VCXH245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B Ports by placing them in a high impedance state. The VCXH245 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 74VCXH245 is designed for low voltage (1.2V to 3.6V) VCC applications. The 74VCXH245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation. Features s 1.2V to 3.6V VCC supply operation s Bushold on data inputs eliminates the need for external pull-up/pull-down resistors s tPD 3.5 ns max for 3.0V to 3.6V VCC s Static Drive (IOH/IOL) r24 mA @ 3.0V VCC s Uses patented Quiet Series noise/EMI reduction circuitry s Latchup performance exceeds 300 mA s ESD performance: Human body model ! 2000V Machine model ! 200V Ordering Code: Order Number 74VCXH245WM 74VCXH245MTC Package Number M20B MTC20 Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel……
