UNISONIC TECHNOLOGIES CO., LTD U74LVC125A CMOS IC QUADRUPLE BUS BUFFER GATE WITH 3-STATE OUTPUTS DESCRIPTION The U74LVC125A consists of four bus buffers with 3-state output controlled by enable input ( ΟΕ ), when ΟΕ 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. FEATURES * Operation Voltage Range: 1.65~3.6V * Low Power Dissipation * Input Accept Voltage to 5.5V ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC125AL-S14-R U74LVC125AG-S14-R U74LVC125AL-P14-R U74LVC125AG-P14-R www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd Package Packing SOP-14 TSSOP-14 Tape Reel Tape Reel 1 of 5 QW-R502-182.C U74LVC125A CMOS IC PIN CONFIGURATION FUNCTION TABLE (each gate) INPUT ΟΕ L L H A L H X OUTPUT Y L H Z LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-182.C U74LVC125A CMOS IC ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~6.5 V Input Voltage VIN -0.5~6.5 V Output Voltage(active mode) VOUT -0.5~VCC+0.5 V Input Clamp Current(ViN<0) IIK -50 mA Output Clamp Current(VO<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 °С Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
