1 / 6 page  UNISONIC TECHNOLOGIES CO., LTD U74LVC2G240 CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2010 Unisonic Technologies Co., Ltd QW-R502-433.A DUAL BUFFER/DRIVER WITH 3-STATE OUTPUTS DESCRIPTION The U74LVC2G240 is a dual buffer or driver with 3-state outputs. It is designed for 1.65V to 5.5V operation. The U74LVC2G240 is composed of two 1-bit buffers/drivers with separate output-enable (OE ) inputs. When OE is low, data passes from A (input) to Y (output). 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 pull-up resistor, and the minimum value of the resistor is determined by the current-sinking capability of the driver. The U74LVC2G240 is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs and prevents damaging current backflow through the device when it is powered down. FEATURES * Wide Supply Voltage Range from 1.65V to 5.5V * Max tPD of 4.6 ns at 3.3V * Up to 5.5V Inputs Accept Voltages * Low Power Consumption, ICC = 10 μA (Max.) * ±24 mA Output Driver at 3.3V * Typical VOLP (Output Ground Bounce) < 0.8V, VCC = 3.3 V, TA = 25 ℃ * Typical VOHV (Output VOH Undershoot) > 2V, VCC = 3.3 V, TA = 25 ℃ TSSOP-8 ORDERING INFORMATION Ordering Number Package Packing U74LVC2G240G-P08-R TSSOP-8 Tape Reel (1) R: Tape Reel (2) P08:TSSOP-8 (3) G: Halogen Free U74LVC2G240G-P08-R (1) Packing Type (2) Package Type (3) Halogen Free |
