SN74AVC8T245 8-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS

SCES517H – DECEMBER 2003 – REVISED FEBRUARY 2007

DESCRIPTION/ORDERING INFORMATION (CONTINUED)

The SN74AVC8T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable ( OE) input can be used to disable the outputs so the buses are effectively isolated.

The SN74AVC8T245 is designed so the control pins (DIR and OE) are supplied by V The SN74AVC8T245 solution is compatible with a single-supply system and can be replaced later with a '245

function, with minimal printed circuit board redesign. This device is fully specified for partial-power-down applications using I

preventing damaging current backflow through the device when it is powered down. The V To ensure the high-impedance state during power up or power down, OE shall be tied to V

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

isolation feature ensures that if either V

CC

input is at GND, both ports are in the high-impedance state.

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS

WWW.100Y.COM.TW WWW.100Y.COM.TW WWW.100Y.COM.TW

compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
