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: 1.6V ~ 5.5V * Low Power Current: ICC=10μA (Max.) * ±24mA Output Drive (VCC=3.0V) * Power Down Protection ORDERING INFORMATION Ordering Number U74LVC1G17G-AE5-R U74LVC1G17G-AF5-R U74LVC1G17G-AL5-R Package SOT-23-5 SOT-25 SOT-353 Packing Tape Reel Tape Reel Tape Reel MARKING 5 4 3A7G 1 2 3 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-080.H 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.H U74LVC1G17 CMOS IC ABSOLUTE MAXIMUM RATING (TA=25°С, unless otherwise specified) (Note 2) PARAMETER Supply Voltage Input Voltage Output Voltage SYMBOL VCC VIN TEST CONDITIONS Output in the high or low state Output in the power-off state VOUT RATINGS -0.5~6.5 -0.5~6.5 -0.5~VCC+0.5 -0.5~6.5 UNIT V V V V Continuous VCC or GND ICC ±100 mA Current Continuous Output Current IOUT ±50 mA Input Clamp Current IIK VIN<0 -50 mA Output Clamp Current IOK VOUT<0 -50 mA Storage Temperature Range TSTG -65 ~+150 °C Notes: 1. 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. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
