The control-function implementation minimizes external timing requirements. These devices allow data transmission 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 device so that the buses are effectively isolated. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC OE B1 B2 B3 B4 B5 B6 B7 B8 A2 A1 DIR VCC OE SN54AHC245 . . . 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 B1 B2 B3 B4 B5 A8 GND B8 B7 B6 A3 A4 A5 A6 A7 ORDERING INFORMATION PDIP – N SN74AHC245N Tube SN74AHC245DW Tape and reel SN74AHC245DWR Tape and reel SN74AHC245DBR Tube SN74AHC245PW Tape and reel SN74AHC245PWR TVSOP – DGV Tape and reel SN74AHC245DGVR HA245 CDIP – J Tube SNJ54AHC245J SNJ54AHC245J CFP – W Tube SNJ54AHC245W SNJ54AHC245W LCCC – FK Tube SNJ54AHC245FK SNJ54AHC245FK SSOP – DB TSSOP – PW –55°C to 125°C TOP-SIDE MARKING Tube SOIC – DW –40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA SN74AHC245N AHC245 HA245 HA245 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
