This device is intended to replace the conventional driver in any speed-critical path. The small propagation delay is achieved using a unity-gain amplifier on the input and feedback resistors from input to output, which allows the output to track the input with a small offset voltage. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides true outputs and symmetrical active-low output-enable (OE) inputs. 1 48 2 47 3 46 4 45 5 44 6 43 7 42 8 41 9 40 10 39 11 38 12 37 13 36 14 35 15 34 16 33 17 32 18 31 19 30 20 29 21 28 22 27 23 26 24 25 2OE 1A1 1A2 GND 1A3 1A4 VCC 2A1 2A2 GND 2A3 2A4 3A1 3A2 GND 3A3 3A4 VCC 4A1 4A2 GND 4A3 4A4 3OE ORDERING INFORMATION SSOP – DL –40°C 40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA TSSOP – DGG TOP-SIDE MARKING Tube SN74ALB16244DL Tape and reel SN74ALB16244DLR Tape and reel SN74ALB16244DGGR ALB16244 ALB16244 TVSOP – DGV Tape and reel SN74ALB16244DGVR AV244 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
