UNISONIC TECHNOLOGIES CO., LTD U74AHC1G125 CMOS IC SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT DESCRIPTION The U74AHC1G125 is a single bus buffer gate/line driver with 3-state output. When OE is high, the Y output are in a high-impedance state. When OE is low, the device passes noninverted data from the A input to the Y output. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. FEATURES * Wide supply voltage range from 2V to 5.5V * Max tPD of 6 ns from A to Y at 5V * Low power consumption, ICC = 1μA (Max) at 5.5V * ±8mA output driver at 5V ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHC1G125L-AF5-R U74AHC1G125G-AF5-R U74AHC1G125L-AL5-R U74AHC1G125G-AL5-R Package Packing SOT-25 SOT-353 Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-683.A U74AHC1G125 PIN CONFIGURATION GND 3 A 2 4 Y CMOS IC OE 1 5 VCC FUNCTION TABLE INPUT A H L X OE L L H OUTPUT Y H L Z LOGIC DIAGRAM (positive logic) OE A 1 2 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 Y 2 of 6 QW-R502-683.A U74AHC1G125 CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Range VCC -0.5~7 V Input Voltage Range VIN -0.5~7 V Output Voltage Range VOUT -0.5~VCC +0.5 V Input Clamp Current (VIN<0) IIK -20 mA Output Clamp Current (VOUT<0, or VOUT>VCC) IOK ±20 mA Output Current IOUT ±25 mA VCC or GND Current ICC ±50 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.
