UNISONIC TECHNOLOGIES CO., LTD U74LVC1G14 CMOS IC SINGLE SCHMITT-TRIGGER INVERTER 3 2 1 5 4 DESCRIPTION SOT-25 The U74LVC1G14 is a single Schmitt-trigger inverter, 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. 3 2 1 5 4 SOT-353 *Pb-free plating product number: U74LVC1G14L FEATURES * Operation Voltage Range: 1.65~5.5V * Low Power Dissipation: ICC=10µA(Max) * 24mA output drive(VCC=3.0V) * High Noise Immunity * Power Down Protection ORDERING INFORMATION Order Number Normal Lead Free Plating U74LVC1G14-AF5-R U74LVC1G14L-AF5-R U74LVC1G14-AL5-R U74LVC1G14L-AL5-R Package Packing SOT-25 SOT-353 Tape Reel Tape Reel U74LVC1G14L-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 1 3A4 Lead Plating 4 5 www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-081,A U74LVC1G14 CMOS IC PIN CONFIGURATION GND 3 A 2 NC 1 4 Y 5 VCC FUNCTION TABLE (each gate) INPUT A L H OUTPUT Y H L LOGIC DIAGRAM (positive logic) A 2 4 Y A UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 4 Y 2 of 5 QW-R502-081,A U74LVC1G14 CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified)(Note 1) PARAMETER Supply Voltage Input Voltage Output Voltage(active mode) 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(VOUT<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.
