When OE is low, the device passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the SN54AC240...FK PACKAGE (TOP VIEW) high-impedance state. To ensure the high-impedance state during power Y4 A1 OE CCOE up or power down, OE should be tied to V 2 1 1V 2 CC through a pullup resistor; the minimum value of 3 2 1 20 19 the resistor is determined by the current-sinking 1A2 4 18 1Y1 capability of the driver. 2Y3 5 17 2A4 1A3 6 16 1Y2 2Y2 7 15 2A3 1A4 8 14 1Y3 9 10 11 12 13 1 D 14 2 Y N AY A 2 G 21 2 ORDERING INFORMATION ORDERABLE TOP-SIDE TA PACKAGE† PART NUMBER MARKING PDIP − N Tube SN74AC240N SN74AC240N Tube SN74AC240DW SSOOIICC − DDWW AACC224400 Tape and reel SN74AC240DWR −4400°CC ttoo 8855°CC SOP − NS Tape and reel SN74AC240NSR AC240 SSOP − DB Tape and reel SN74AC240DBR AC240 Tube SN74AC240PW TTSSSSOOPP − PPWW AACC224400 Tape and reel SN74AC240PWR CDIP − J Tube SNJ54AC240J SNJ54AC240J −5555°CC ttoo 112255°CC CFP − W Tube SNJ54AC240W SNJ54AC240W LCCC − FK Tube SNJ54AC240FK SNJ54AC240FK †Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. 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 <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
