UNISONIC TECHNOLOGIES CO., LTD U74LVC2G240 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 shou.

UNISONIC TECHNOLOGIES CO., LTD U74LVC2G240 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 °C * Typical VOHV (Output VOH Undershoot) > 2V, VCC = 3.3 V, TA = 25 °C  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC2G240L-SM1-R U74LVC2G240G-SM1-R U74LVC2G240L-P08-R U74LVC2G240G-P08-R Package MSOP-8 TSSOP-8 CMOS IC MSOP-8 TSSOP-8 Packing Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-433.B U74LVC2G240  MARKING MSOP-8  PIN CONFIGURATION TSSOP-8 CMOS IC  FUNCTION TABLE (Each Buffer) INPUTS OE L L H A H L X OUTPUT Y L H Z  LOGIC DIAGRAM (Positive Logic) 1 1OE 1A 2 6 1Y 7 2OE 2A 5 3 2Y UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-433.B U74LVC2G240 CMOS IC  ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~6.5 V Input Voltage Output Voltage (any output in the high-impedance or power-off state) VIN VOUT -0.5~6.5 -0.5~6.5 V V Output Voltage (any output in the high or low state) VOUT -0.5~VCC+0.5 V Input Clamp Current IIK -50 mA Output Clamp Current Output Current IOK -50 mA IOUT ±50 mA VCC or GND Current ICC ±100 mA Storage Temperature TSTG -65 ~ +150 °C Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.  THERMAL DATA PARAMETER Junction to Ambient MSOP-8 TSSOP-8 SYMBOL θJA RATINGS 220 190 UNIT °C/W °C/W  RECOMMENDED OPERATING CONDITIONS PARAMETER Supply Voltage High-Level Input Voltage Low-Level Input Voltage Input Voltage Output Voltage High-Level Output Current Low-Level Output Current Input Transition Rise or Fall Rate Operating Temperature SYMBOL VCC VIH VIL VIN VOUT IOH CONDITIONS Operating Data retention only VCC = 1.65V to 1.95V VCC = 2.3V to 2.7V VCC = 3V to 3.6V VCC = 4.5V to 5.5V VCC = 1.65V to 1.95V VCC = 2.3V to 2.7V VCC = 3V to 3.6V VCC = 4.5V to 5.5V High or low state 3-state VCC=1.65V VCC=2.3V VCC=3V VCC=4.5V VCC=1.65V VCC=2.3V IOL VCC=3V tR / tF TOPR VCC=4.5V VCC=1.8±0.15V, 2.5±0.2V VCC=3.3±0.3V VCC=5.0+0.5V MIN 1.65 1.5 0.65× VCC 1.7 2 0.7×VCC 0 0 0 -40 TYP MAX UNIT 5.5 V V 0.35×VCC 0.7 0.8 V 0.3×VCC 5.5 V VCC 5.5 V -4 -8 -16 mA -24 -32 4 8 16 mA 24 32 20 10 ns/V 5 85 °C UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 6 QW-R502-433.B U74LVC2G240 CMOS IC  ELECTRICAL CHARACTERISTICS (TA =25°C , VCC = 3.3 V, unless otherwise specified) PARAMETER High-Level Output Voltage Low-Level Output Voltage Input Leakage Current (A or OE inputs) OFF-State Current High-Impedance State Current Quiescent Supply Current Additional quiescent Supply Current Input Capacitance Output Capacitance SYMBOL VOH VOL TEST CONDITIONS VCC=1.65V~5.5V, IOH=-100μA VCC=1.65V, IOH=-4mA VCC=2.3V, IOH=-8mA VCC=3V, IOH=-16mA VCC=3V, IOH=-24mA VCC=4.5V, IOH=-32mA VCC=1.65V~5.5V, IOL=100μA VCC=1.65V.
