UNISONIC TECHNOLOGIES CO., LTD U74LVC1G17 CMOS IC SINGLE SCHMITT-TRIGGER BUFFER DESCRIPTION The UTC U74LVC1G17 is a single Schmitt-trigger buffer, it provides the function Y=A. The device have different input threshold levels for positivegoing (VT+) and negative-going(VT-) signals because of the Schmitt-trigger action in the input. This device has power-down protective circuit, preventing device destruction when it is powered down. FEATURES * Operation Voltage Range: 1.65~5.5V * Low Power Dissipation: ICC=10µA (Max) * 24mA Output Drive(VCC=3.0V) * High Noise Immunity ICC=10µA (Max) * Power Down Protection ICC=10µA (Max) ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC1G17L-AE5-R U74LVC1G17G-AE5-R U74LVC1G17L-AF5-R U74LVC1G17G-AF5-R U74LVC1G17L-AL5-R U74LVC1G17G-AL5-R Package Packing SOT-23-5 SOT-25 SOT-353 Tape Reel Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-080,F U74LVC1G17 PIN CONFIGURATION FUNCTION TABLE (each gate) INPUT A L H CMOS IC OUTPUT Y L H LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-080,F U74LVC1G17 CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified)(Note 1) 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 Output Voltage(power-down mode) VOUT -0.5~6.5 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 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.
