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 blank pullup resistor; the minimum value of the resistor is blank determined by the current-sinking capability of the driver. blank ORDERING INFORMATION TA PACKAGE(1) ORDERABLE PART NUMBER TOP-SIDE MARKING FBGA – GRD SN74ALVCH16244GRDR Tape and reel VH244 FBGA – ZRD (Pb-free) SN74ALVCH16244ZRDR Tube SN74ALVCH16244DL SSOP – DL ALVCH16244 Tape and reel SN74ALVCH16244DLR SN74ALVCH16244DGGR –40 °C to 85°C TSSOP – DGG Tape and reel ALVCH16244 74ALVCH16244DGGRE4 SN74ALVCH16244DGVR TVSOP – DGV Tape and reel VH244 74ALVCH16244DGVRE4 VFBGA – GQL SN74ALVCH16244KR Tape and reel VH244 VFBGA – ZQL (Pb-free) 74ALVCH16244ZQLR (1) Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
