SN74BCT2241 OCTAL BUFFER AND LINE/MOS DRIVER WITH 3-STATE OUTPUTS SCBS035D – SEPTEMBER 1988 – REVISED MARCH 2003 D D D D D DW, N OR NS PACKAGE (TOP VIEW) Operating Voltage Range of 4.5 V to 5.5 V State-of-the-Art BiCMOS Design Significantly Reduces ICCZ Output Ports Have Equivalent 33-Ω Series Resistors, So No External Resistors Are Required 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) 1OE 1A1 2Y4 1A2 2Y3 1A3 2Y2 1A4 2Y1 GND description/ordering information 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC 2OE 1Y1 2A4 1Y2 2A3 1Y3 2A2 1Y4 2A1 This SN74BCT2241 is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the ’BCT2240 and ’BCT2244 devices, this device provides the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs. This device features high fan-out and improved fan-in. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver. The outputs, which are designed to source or sink up to 12 mA, include 33-Ω series resistors to reduce overshoot and undershoot.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check 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 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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
