Low Voltage Bidirectional Transceiver with Bushold
74VCXH245 Low Voltage Bidirectional Transceiver with Bushold June 1999 Revised August 2003 74VCXH245 Low Voltage Bidirectional Transceiver with Bushold General Description Features The VCXH245 contains eight non-inverting bidirectional1.2V to 3.6V V supply operation CC buffers with 3-STATE outputs and is intended for bus ori- Bushold on data inputs eliminates the need for external ented applications. The T/R input determines the direction pull-up/pull-down resistors of data flow. The OE input disables both the A and B Ports t PD by placing them in a high impedance state. The VCXH245 data inputs include active bushold circuitry, eliminating the 3.5 ns max for 3.0V to 3.6V V CC need for external pull-up resistors to hold unused or float- Static Drive (I /I ) OH OL ing data inputs at a valid logic level. ±24 mA @ 3.0V V CC The 74VCXH245 is designed for low voltage (1.2V to 3.6V) Uses patented Quiet Series noise/EMI reduction V applications. CC circuitry The 74VCXH245 is fabricated with an advanced CMOS Latchup performance exceeds 300 mA technology to achieve high-speed operation while main- taining low CMOS power dissipation.ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Order Number Package Number Package Description 74VCXH245WM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 74VCXH245MTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
