SN54F240, SN74F240 OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS SDFS061A – D2932, MARCH 1987 – REVISED OCTOBER 1993 • SN54F240 . . . J PACKAGE SN74F240 . . . DB, DW, OR N PACKAGE (TOP VIEW) 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers Package Options Include Plastic Small-Outline (SOIC) and Shrink Small-Outline (SSOP) Packages, Ceramic Chip Carriers, and Plastic and Ceramic DIPs 1OE 1A1 2Y4 1A2 2Y3 1A3 2Y2 1A4 2Y1 GND description These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Taken together with the ′F241 and ′F244, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs, and complementary OE and OE inputs. 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 2Y4 1A1 1OE VCC SN54F240 . . . FK PACKAGE (TOP VIEW) The ′F240 is organized as two 4-bit buffers/line drivers with separate output enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. 1A2 2Y3 1A3 2Y2 1A4 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 1Y1 2A4 1Y2 2A3 1Y3 2Y1 GND 2A1 1Y4 2A2 The SN74F240 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area. 2OE • The SN54F240 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74F240 is characterized for operation from 0°C to 70°C.

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) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
