1 / 10 page SN74ALVC162834 18-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS SCES172A – DECEMBER 1998 – REVISED FEBRUARY 1999 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Member of the Texas Instruments Widebus ™ Family D EPIC™ (Enhanced-Performance Implanted CMOS) Submicron Process D Outputs Have Equivalent 26-Ω Series Resistors, So No External Resistors Are Required D ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) D Latch-Up Performance Exceeds 250 mA Per JESD 17 D Package Options Include Plastic Shrink Small-Outline (DL), Thin Shrink Small-Outline (DGG), and Thin Very Small-Outline (DGV) Packages description This 18-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. 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. 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 outputs, which are designed to sink up to 12 mA, include equivalent 26- Ω resistors to reduce overshoot and undershoot. The SN74ALVC162834 is characterized for operation from –40 °C to 85°C.
