UNISONIC TECHNOLOGIES CO., LTD U74LVC2G125 CMOS IC DUAL BUS BUFFER GATE WITH 3-STATE OUTPUTS DESCRIPTION MSOP-8 The U74LVC2G125L consists of two bus buffers with 3-state output controlled by enable input (nOE), when nOE is high, the output is disable. Inputs can be driven from either 3.3V or 5V devices, so the device can be used in a mix 3.3V/5V system. This device is full specified for partial power-down protective circuit, preventing the backflow current through the device when it is powered down. FEATURES * Operation Voltage Range: 1.65~5.5V * Low Power Dissipation * Input Accept Voltage to 5.5V TSSOP-8 Lead-free: U74LVC2G125L Halogen-free: U74LVC2G125G ORDERING INFORMATION Normal U74LVC2G125-P08-R U74LVC2G125-P08-T U74LVC2G125-SM1-R U74LVC2G125-SM1-T Ordering Number Lead Free Plating U74LVC2G125L-P08-R U74LVC2G125L-P08-T U74LVC2G125L-SM1-R U74LVC2G125L-SM1-T www.unisonic.com.tw Copyright © 2008 Unisonic Technologies Co., Ltd Halogen Free U74LVC2G125G-P08-R U74LVC2G125G-P08-T U74LVC2G125G-SM1-R U74LVC2G125G-SM1-T Package Packing TSSOP-8 TSSOP-8 MSOP-8 MSOP-8 Tape Reel Tube Tape Reel Tube 1 of 6 QW-R502-136.B U74LVC2G125 CMOS IC PIN CONFIGURATION 1OE 1 VCC 1A 2 7 2OE 2Y 3 6 1Y GND 4 5 2A FUNCTION TABLE (each gate) INPUT nOE L L H 8 A L H X OUTPUT Y L H Z LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-136.B U74LVC2G125 CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified)(Note 1) PARAMETER SYMBOL RATINGS UNIT VCC -0.5~6.5 V VIN -0.5~6.5 V Enable mode VOUT -0.5~VCC+0.5 V Output Voltage Disable mode VOUT -0.5~6.5 V Power-down mode VOUT -0.5~6.5 V Input Clamp Current(ViN<0) IIK -50 mA Output Clamp Current(VOUT<0) IOK -50 mA Output Current IOUT ±50 mA VCC or GND Current ICC ±100 mA Power Dissipation PD 500 mW Storage Temperature TSTG -65 ~ +150 ℃ 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.
