| UNISONIC TECHNOLOGIES CO., LTD U74LVC1G17 SINGLE SCHMITT-TRIGGER BUFFER DESCRIPTION The U74LVC1G17 is a single Schmitt-trigger buffer, it provides the function Y=A. The device have different input threshold levels for positive- going (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. 4 3 2 1 CMOS IC 5 SOT-25 2 1 3 5 4 FEATURES * Operation Voltage Range: 1.65~5.5V * Low Power Dissipation: ICC=10A(Max) * 24mA output drive(VCC=3.0V) * High Noise Immunity * Power Down Protection SOT-353 *Pb-free plating product number: U74LVC1G17L ORDERING INFORMATION Order Number Normal Lead Free Plating U74LVC1G17-AF5-R U74LVC1G17L-AF5-R U74LVC1G17-AL5-R U74LVC1G17L-AL5-R Package SOT-25 SOT-353 Packing Tape Reel Tape Reel U74LVC1G17L-AF5-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel (2) AF5: SOT-25, AL5: SOT-353 (3) L: Lead Free Plating, Blank: Pb/Sn MARKING 3 2 3A7 4 5 1 Lead Plating www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-080,A U74LVC1G17 PIN CONFIGURATION GND 3 A 2 NC 1 CMOS IC 4 Y 5 VCC FUNCTION TABLE (each gate) INPUT A L H OUTPUT Y L H LOGIC DIAGRAM (positive logic) A 2 4 Y A 2 4 Y UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-080,A U74LVC1G17 ABSOLUTE MAXIMUM RATING (unless otherwise specified)(Note 1) PARAMETER Supply Voltage Input Voltage Output Voltage(active mode) CMOS IC SYMBOL RATINGS UNIT VCC -0.5~6.5 V VIN -0.5~6.5 V 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 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.
