SN74ALVC16334 16-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS SCES128C – FEBRUARY 1998 – REVISED FEBRUARY 1999 D D D D D D D DGG, DGV, OR DL PACKAGE (TOP VIEW) Member of the Texas Instruments Widebus Family EPIC (Enhanced-Performance Implanted CMOS) Submicron Process Ideal for Use in PC100 Register DIMM Designed to Comply With JEDEC 168-Pin and 200-Pin SDRAM Buffered DIMM Specification ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) Latch-Up Performance Exceeds 250 mA Per JESD 17 Package Options Include Plastic Shrink Small-Outline (DL), Thin Shrink Small-Outline (DGG), and Thin Very Small-Outline (DGV) Packages OE Y1 Y2 GND Y3 Y4 VCC Y5 Y6 GND Y7 Y8 Y9 Y10 GND Y11 Y12 VCC Y13 Y14 GND Y15 Y16 NC description This 16-bit universal bus driver is designed for 1.65-V to 3.6-V VCC operation. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CLK) input is held at a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE is high, the outputs are in the high-impedance state. 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 CLK A1 A2 GND A3 A4 VCC A5 A6 GND A7 A8 A9 A10 GND A11 A12 VCC A13 A14 GND A15 A16 LE NC – No internal connection 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. The SN74ALVC16334 is characterized for operation from –40°C to 85°C.
