Low Voltage Bidirectional Transceiver with Bushold
74ALVCH245 Low Voltage Bidirectional Transceiver with Bushold September 2001 Revised February 2002 74ALVCH245 Low Voltage Bidirectional Transceiver with Bushold General Description Features The ALVCH245 contains eight non-inverting bidirectional1.65V 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 ALVCH245 data inputs include active bushold circuitry, eliminating the 3.6 ns max for 3.0V to 3.6V V CC need for external pull-up resistors to hold unused or float- 4.2 ns max for 2.3V to 2.7V V CC ing data inputs at a valid logic level. 6 ns max for 1.65V to 1.95V V CC The 74ALVCH245 is designed for low voltage (1.65V to Uses patented Quiet Series noise/EMI reduction 3.6V) V applications. CC circuitry The 74ALVCH245 is fabricated with an advanced CMOS Latchup conforms to JEDEC JED78 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 74ALVCH245WM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 74ALVCH245MTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
