UNISONIC TECHNOLOGIES CO., LTD U74AHC1G126 Preliminary CMOS IC SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT DESCRIPTION The U74AHC1G126 is a single bus buffer gate/line driver with 3-state output. When OE is low, the Y output are in a high-impedance state. When OE is high, 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 GND through a pull-down 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 = 1 μA (Max.) at 5.5V * ±8 mA output driver at 5V ORDERING INFORMATION Order Number Normal Lead Free Plating U74AHC1G126L-AL5-R U74AHC1G126G-AL5-R www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package Packing SOT-353 Tape Reel 1 of 6 QW-R502-782.a U74AHC1G126 Preliminary PIN CONFIGURATION FUNCTION TABLE INPUT OE H H L A H L X CMOS IC OUTPUT Y H L Z LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-782.a U74AHC1G126 Preliminary CMOS IC ABSOLUTE MAXIMUM RATING 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 θJA °C /W Package Thermal Impedance 250 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.
