The ’AHC240 devices are 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. 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 SN54AHC240 . . . FK PACKAGE (TOP VIEW) To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 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 1A2 2Y3 1A3 2Y2 1A4 2OE D D ORDERING INFORMATION PDIP – N SN74AHC240N Tube SN74AHC240DW Tape and reel SN74AHC240DWR SOP – NS Tape and reel SN74AHC240NSR AHC240 SSOP – DB Tape and reel SN74AHC240DBR HA240 Tube SN74AHC240PW Tape and reel SN74AHC240PWR TSSOP – PW –55°C to 125°C TOP-SIDE MARKING Tube SOIC – DW –40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA SN74AHC240N AHC240 HA240 TVSOP – DGV Tape and reel SN74AHC240DGVR HA240 CDIP – J Tube SNJ54AHC240J SNJ54AHC240J CFP – W Tube SNJ54AHC240W SNJ54AHC240W LCCC – FK Tube SNJ54AHC240FK SNJ54AHC240FK † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
