SN74ALVCH16244 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS www.ti.com SCES014K - JULY 1995 - REVISED OCTOBER 2005 FEATURES * * * * * * * Member of the Texas Instruments WidebusTM Family Operates From 1.65 V to 3.6 V Max tpd of 3 ns at 3.3 V 24-mA Output Drive at 3.3 V Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors Latch-Up Performance Exceeds 250 mA Per JESD 17 ESD Protection Exceeds JESD 22 - 2000-V Human-Body Model (A114-A) - 200-V Machine Model (A115-A) DGG, DGV, OR DL PACKAGE (TOP VIEW) DESCRIPTION/ORDERING INFORMATION This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation. 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. 1OE 1Y1 1Y2 GND 1Y3 1Y4 VCC 2Y1 2Y2 GND 2Y3 2Y4 3Y1 3Y2 GND 3Y3 3Y4 VCC 4Y1 4Y2 GND 4Y3 4Y4 4OE 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 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 TA FBGA - GRD FBGA - ZRD (Pb-free) SSOP - DL -40C to 85C TSSOP - DGG TVSOP - DGV VFBGA - GQL VFBGA - ZQL (Pb-free) (1) PACKAGE (1) Tape and reel Tube Tape and reel Tape and reel Tape and reel Tape and reel ORDERABLE PART NUMBER SN74ALVCH16244GRDR SN74ALVCH16244ZRDR SN74ALVCH16244DL SN74ALVCH16244DLR 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.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder Addendum-Page 1 PACKAGE OPTION ADDENDUM www.ti.com 30-Mar-2007 temperature.
