UNISONIC TECHNOLOGIES CO., LTD U74AHCT1G126 CMOS IC SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT DESCRIPTION The UTC U74AHCT1G126 is a single bus buffer gate with 3-state output controlled by enable input (OE), When OE is LOW and the output is disabled. FEATURES * Operation Voltage Range: 4.5~5.5V * Low Power Dissipation: ICC=1μA (Max.) @25°C * Inputs are TTL-Voltage Compatible ORDERING INFORMATION Ordering Number U74AHCT1G125G-AF5-R U74AHCT1G125G-AL5-R Package SOT-25 SOT-353 Packing Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-096.E U74AHCT1G126 CMOS IC PIN CONFIGURATION VCC 5 1 OE 2 A 3 GND FUNCTION TABLE (each gate) INPUT OE H H L Y 4 A L H X OUTPUT Y L H Z LOGIC DIAGRAM (positive logic) Logic symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw IEC logic symbol 2 of 5 QW-R502-096.E U74AHCT1G126 CMOS IC ABSOLUTE MAXIMUM RATINGS (unless otherwise specified)(Note 1) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7 V Input Voltage VIN -0.5~7 V Output Voltage VOUT -0.5~VCC+0.5 V Input Clamp Current IIK -20 mA Output Clamp Current IOK ±20 mA Output Current IOUT ±25 mA VCC or GND Current ICC ±50 mA Storage Temperature TSTG -65 ~ +150 °C Notes: 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.
