The SN74ALVCH16244 is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE) inputs. 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. 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 blank blank blank ORDERING INFORMATION PACKAGE (1) TA FBGA – GRD FBGA – ZRD (Pb-free) SSOP – DL –40°C to 85°C SN74ALVCH16244DL Tape and reel SN74ALVCH16244DLR Tape and reel TVSOP – DGV Tape and reel VFBGA – ZQL (Pb-free) SN74ALVCH16244ZRDR Tube TSSOP – DGG VFBGA – GQL (1) Tape and reel ORDERABLE PART NUMBER SN74ALVCH16244GRDR Tape and reel SN74ALVCH16244DGGR 74ALVCH16244DGGRE4 SN74ALVCH16244DGVR 74ALVCH16244DGVRE4 SN74ALVCH16244KR 74ALVCH16244ZQLR TOP-SIDE MARKING VH244 ALVCH16244 ALVCH16244 VH244 VH244 Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
